I have been looking around and doing a lot of reading on third gens. i want to buy one soon. After all my research, I think that i WANT to go with a TBI engine over the TPI. From what i understand it is cheaper and easier to mod. Anyone have any comments? I just wish they put TBIs in GTAs.WANT

I love TBI, my 4200 pound 89 truck, will destroy a stock 89 TPI Iroc. But with mods the TPI is awesom.

I know this is the TBI board, but if I knew the difference between TBI and TPI when I was looking for a car I definitely would have gotten a TPI.

I like the Reliability and the Low Maintenance cost of the TBI but, I like the Looks and the performance of the TPI engine even though it has some drawbacks ( high cost of stock and aftermarket parts, high labor rates for repair work and ease of maintenance). If I had to do it over again, I'd probably get the TPI because it looks so Cool when you open up the hood.

I like the challenge of making this car fast (it's not particularly hard through). I like saying that I have a 305 tbi when I beat people

i would hope so with the mods you got. tell me again, i forgot, which induction system was used in the corvette and which was used in trucks? people say i like the driveability and reliability of TBI, GUESS WHAT - TPI is an EFI system to, it starts cold w/o pumping the pedal also guys.........


just my opinion from a CARB guy

My roomate has TPI, so I do have a pretty good understanding of it. But it has some downfalls like a sevre power drop off after 5000rpm, thats why he is switching to the LT1 intake. TBI can be found at most pick a parts, so its cheap and easy. I will admit that given to equal motors will slight modding, TPI will make more power than the TBI.

Not to rag on this much, but yesterday I was racing a similar 305 TPI with identical mods to mine save for a 3" cat back for his car and we were running neck and neck for 12 straight runs.

I'd always have him on the line and 60ft and he'd edge me at the end by a nose...

Slade,

Just for sh!ts and giggles, what kind of times were you guys running?

All day 15.6 avg for him and 15.8 for me...

It was kinda fun though since I started the day at mid 16's then we went serious and dropped rear air pressure and got the ice out.

At that point he had 0.5 on me then I looked at his hood and noticed his base timing was at 6 advanced and mine was 0.

One of the other members of our board noted that too since mine was a TBI and timing is a snap just like a carb we went 6 advanced too on mine. Instantly had a 15.8 on the next run and we were neck and neck for the next 7 runs.

I always had him off the line, my 60 ft as low as 2.204 where he couldn't break 2.3 but he always had me after the 330 ft mark and our 3rd shift he pulled slightly to get a nose ahead of me.
It was really weird though noting the differences, I always finished the 1/4 mile with a higher trap mph than him. I got 89 mph and he never got past 87 mph on the traps. The midrange torque of the TPI is what's edging me. With some minor work mostly exhaust I could easily have him. He has a 3 inch cat back where I got the stock tubing...

I had a TBI 305 and did a lot of research trying to find parts for it. I found out that it would cost me quite a few dollars just to bring it to the stock HP and torque outputs of an L98 TPI engine. I sold my anemic TBI which could only muster mid 16s with minor mods (thermostat, open element) for an L98 IROC which I've gteched a 14.6 with my dynomax catback and shorty headers. The TBI peaked much lower than my TPI which revs happily up to 4500 rpm (and can be tweaked to make serious gains at 5000 rpm). It's a much more versatile engine and can get better HP/$ gains. Don't get me wrong, the 305 itself can be made to make very good amounts of power, but TBI just doesn't cut it for me.

If all you care about is what is cheaper and easier to mod, then get a carbureted car. Those of us who want real power and a great all-around package will stick with TPI.

I hate to say this but its the cubes that give the l98 its major advantage...

At the track there was a 355 with carb on top and it was edging out a l98 with 10.1 compression, heads, porting, headers... 14.6 Carb vs 14.8 TPI

Virtually identical 305's at the track were running neck and neck the whole day... I was not smoked by tpi by much 0.2 tenths of a sec which can easily be attributed to exhaust (3 inch cat back) + 8 injectors... I got nailed by a carb 305 though... he had cam and true dual exhaust so knew where he got me...

I have to ask though, is the pain of 8 injectors worth it? (2 members on the ontario board had injectors die on them this year, my father lost 2 sets in 1 year back in 85)

My injectors are 14 years old now...

The same thing that will wake up a TPI, (headers + cam) will do the same for a TBI so is there a real advantage?

Those TPI parts intake, plenum, injectors will run you much more than the 670 TBI + intake upgrade, so where's the advantage?

I have proven it on track now that a TPI injection system holds only a very small advantage over a TBI setup... even that may not be true though that they could be very well... equal...

on top of that my tbi is much more reliable... 30 mpg (I thank my father for his "kind" experiences on the matter)

Slade two slow *** cars racing each other doesnt prove a thing. If you want factual proof then ask Kevin91z what his dads car dynoed at before and after a TBI-TPI swap(only the induction systems changed). You might be surprised.

I'll save you the trouble of asking. My dad gained 17 RWHP and 70 RWTQ from swapping his stock 305 TBI to a TPI intake. He kept everything stock TBI, including the cam, heads, exhaust manifolds, etc. He also gained 2-3 miles per gallon with the TPI swap, as well. After swapping in an LT1 cam, he had a best run of 14.94 . There are no times with the TBI cam, because it would be too embaressing.

I'd like to point out the gains from a tpi intake aren't as big as oh say the gains from a 350 drop or cam install...

At the track another member happened to have a 305 tpi with dual cat 350 cam option... he pulled in 15.1 over the other tpi car with the same cam exhaust as me.. the 350's were well into the 14 range (carb/tpi) as well so I'm willing to bet more money on cubes and cam than I would on tpi intake.

On top of that, an old lg4 305 with dual exhaust and large cam and a 355 carb with cam and headers pulled in the more impressive times than the efi's for the day showing full well that cubes and cam are more important to power than intake alone...

I was sure I could get the tbi into 15's without touching the engine and I did it on a hot humid day too, I'm sure if I just dab into the engine a little I can get it into 14's...

Now how's that for a car that's still 100% emissions friendly with a comfortable a/c system still working? (smog equipment intact)

On top of that I have 183 000 + miles on it and its winter driven...

I'm not saying tpi is a bad system, I'm just saying that if you know a bit about what you're doing, you can achieve anything... simply dropping in a carb or tpi will not get you miracle numbers...
I gained as much as 30 rw tq and 20 rwhp since my initial dyno 2 years ago went from 230 rwtq to 255 rwtq and gained from 140 rwhp to 150 rwhp from a simple pulley, cat and flowmaster install... that was with a stock ignition coil, 14 years old, stock wires 7 mm and 4 years old and plain old delco plugs and base timing...

Considering that I've done a tuneup with blaster coil install that did give a significant boost to performance, I'd have to say I'm close to acheiving the full stock flywheel numbers at the rw... but I'll let the dyno tell me that in a month...

Kevin, was the dyno done before or after the cam swap??? I know full well the times he's pulling is a direct result of the cam more so than the intake...

Yup, what he said. Except, carbs make good power too.

Carbs are so much cheaper to mod than TPI and yes, they ware cheaper to mod than TBI.

Letr me get this straight you are sayig that Cubes will make more power than a simple induction swap? Ya' Think!
That has nothing to do with anything.

He had a 305 and he switched induction systems and picked up 17 hp and 70 ftlbs at the rear wheels period. TBI is not on par with TPI pr Carbs and members times and before and after dyno runs have shown that agian and agian and agian.

TbI's them selves can be hogged out to become decent for performance, TBI intakes suck. TPI is a good performer stock, or it can get new runners and a port job and perform pretty good.
Not to mention TPI is multi point fuel injected. Put I think that a really good carb intake with a hogged out TBI, or 670 tbi, can hands down make more hp (probably less tourque) than a modded TPI.

Well members times , dyno slips and exprience has proven that quite wrong. TBI"er keep saying it but I hasnt happened.

There are a lot of very fast TPI cars out there, thats for sure. But put my tbi motor in a third gen with some slicks on the back, it might go high 12s.

STOP ALL THE BS AND READ THIS POST AGAIN

How about one of these for $500. The TB was homemade so it cost nothing. Is that expensive? How much power do you think can be made?

hectorsn

Thats my next plan, I'm going to get injectors, fuel rails, and new computer, then tap out my intake for multipoint. Then just mount a 1000cfm open trottle body on top.

I know we're getting off topic here but take a look at the pic. Like I mentioned before it was free. Ugly, but free. The 4 Franklins are better looking, in my opinion, and I got to keep them.

I think its common knowledge that the tbi intake is a clunker.
With a good intake and the U. TBI mods. Would you think it added about 10hp? If so then I would think the difference would be more like 7hp difference.
I agree that TPI makes more power, but how much more if the intake has been replaced and the TBI was modded?

Does it matter? If you really want to compare apples to apples, you compare stock to stock. If you want to throw a modded TBI and a different intake manifold on there, I'm gonna siamese the base and port the plenum (both free) and put the difference right back.

I dont understand all the arguing here about dyno numbers. If you dont like the results, I tell you what... go do your own back-back comparo and tell me what you get. Maybe you'll get lucky and get the results you want to see but I kinda doubt it. I know Don and looking at the change he got I think its impossible.

0 celcius? Gtech? I know stock 89 Irocs that'll run that number on that instrument in that temp. Destroy? I think not.

Since you are harping on the he said-she said thing... With a different cam (ditched the peanut), hypercrap chip, and dynomax muffler+tailpipes, and K+N, I ran a 15.2 with my 305 TPI. No other mods. Auto trans, 3.27 rear diff, stock cat, no underdrive, no fancy coil, non-ported heads, same size tires. You ran a 15.8? My car has never been that slow, not even when it was totally stock. And its an 86, so it had a peanut cam and lousy programming.

Thats pretty pathetic. My stock 89 350 convertible ran a 14.96 a month ago, and its totally stock and in need of a general tuneup.

Ummm, what difference does 8 injectors make? I thought A/F ratio was A/F ratio. Especially on such slow cars, fueling shouldnt be an issue.

You really think dual exhaust does anything?

Dont know where you shop or what your friends do to their cars, but currently my injectors on my vert are 13 years old and havent been replaced. They're fine too. The ones on my 86 I replaced because I was chasing another problem and I just needed to eliminate all variables. So happens those injectors still havent been cleaned or anything, and they are on another car right now. 16 years old and over 160k miles. Besides, a set of SVO injectors is cheap anyway, couldnt be much more than $300CDN. Here, they are 200, a pair of TBI injectors costs almost that much. I'm not feeling any pain here.

17hp, 70tq. Is it worth it? Not up to me to decide, I dont have TBI and dont have to worry about thinking about it.

I'm thinking not. Either you can siamese the base and pick up 20+ hp or get a stealth ram for ~$400 which cant be any more than a new 670TB and a new intake manifold.

.2 of a second is, arguably, about 20hp. Kinda matches Don's dyno info, no?

This is just a bunch of crap. I've had a TPS go bad (from a jerkoff mechanic who diced one of my spark plug wires and as I found out, that kills TPS sensors.. along with water from a hose (thats a warning to the clean freaks)). My 85 TPI I got 29.4MPG and it was faster than your car. Even Glenn was getting more than 30mpg with his 350TPI, and I have no doubts his car is faster. I cant say much more than that.

Am I picking on you Slade? I guess so. The amount of ludicrous BS you are spreading here I just couldnt ignore. If you want to wave the TBI banner, thats your choice. Spreading a bunch of misinformation and rumors because your pride and closed eyes are getting in the way is something I just cannot and will not ignore. Induction pride is nice and all, but pretty stupid I think when you have to resort to bending the truth to make your induction system look better.

Want? Hmmmm. I dont know anyone here, if they had the choice, that would pick a lower output motor over a higher output one. The TBI heads are junk, they belong in a trashcan if you want to make any serious power. Same goes for the intake, at least most people agree with that. The stock exhaust is garbage... if you are going to all the trouble of replacing most of the power making components on the car, why even bother getting a TBI? Why not just get a V6 or 4 banger (they're cheaper) and drop a 400 small block in there with a carb? I'd bet you could do that for less than you could pick up an entire TBI car for, and it'd be alot faster. If you really wanted TBI, go rob one off a junkyard car and use it. Seems pointless to me to run a 305 with a bunch of low performance parts on it and try to make it fast, when there are much better choices to be made.

If you happen to have found a TBI car for $500, please disregard the previous remarks.

Ok, dunno why the tpi people love jumping into a TBI forum to put down us tbi owners, but I guess its their way of putting themselves up. I don't go parading a TBI, I responded to a member that said he wanted tbi and I gave him real world info, not some blown up bs I pulled out of my ***.

You did a real number on a fellow TPI member by smashing his stock tpi and saying it was slow and had no relevance when IT WAS A TPI that had identical parts like my car and had the 3 inch cat back advantage making the only real difference the injection system. Making that comparison quite valid that I had a TBI setup running well with a TPI all day. No ultimate TBI, no fuel pressure no radiusing/siamesing. It was stock for stock. We both had pulley's, both had flowmaster's, both had Ram air, both had 6 degrees timing. That in itself says a lot for a lowly tbi that runs in pure stock 16-17 secs. You say that you ran 15.2 WITH A CAM. Well yeah, so did Palric, he knows he has a 350 cam and dual cat from stock, he did buy a formula with the special 230 hp/325 ftlb setup... So we know the peanut cam sucks, this TPI and this TBI both had the same cam... Identical... shall I say it again I-freaking-dentical setups.

I'd never go and smash a tpi saying it was slow, I simply stated it was overrated. If I were to adore an injection system, its the SFI system as that is in essence the best of the best injection systems hands down. The stock tpi intake was designed for a 305, we all know that well.

Another matter is that you smashed even more of this forums members by dissing up their engine's without even taking into conditions like weather and such... if their cars were having issues... we were running in 100+ degree weather with 70% humidity all day, so obviously the runs weren't the best of the best but it was a good comparison of the cars that were there and the mods that differentiated between them. The 355 carb can pull an easy 100+ mph trap time, but due to lack of traction he pulls those times.

You totally disregarded my statements that other members of this board went through costly injector swaps just recently. The multecs are crap. Try and preach that multecs are the best and I know a lot of members will disagree. My father was one of the early tpi owners in 85 and he hated its initial design. TPI injectors here cost cost at minimum $500 cdn for stock lbs... don't tell me that is cheap... I haven't had to replace my injectors, 14 years old and 180 000 miles on those injectors AND winter driven.

I never attacked you or said that TPI is slower than TBI. I just said that TBI isn't as bad as people make it out to be. READ THE TOPIC OF THE POST FIRST BEFORE YOU SHOOT YOUR MOUTH OFF.

You did 15.2 with a cam? If you can pull 15.8 on a 14 year old 180 000 mile car that supposedly runs 16.5-17s with the peanut cam, then brag. What exactly did your car run with the peanut cam hmmm??? Could it be that it runs 15.6 avg with the peanut cam??? Guess what, that is what changing the cam DOES. The peanut cam is bad, hence the great increase. With a peanut cam I don't imagine a TPI305 making 15.2's... that cam hurts any engine. 0.2 sec does not equate to 20 hp. If that were true the 14.6 stock l98's should be running 120 more horse than me, dyno numbers say they only run 220 avg hp which is not the 0.2:20 hp ratio by a long shot...

I am in the process of putting together a TBI with the same parts of a TPI in order to get a true comparison. The TBI came with everyone agrees the crappiest parts available... crap heads, peanut cam, low flow intake, log headers, crap differential.. the list goes on... what if a TBI got the same parts as a TPI what is the true difference there? I'm doing this one piece at a time and so far I'm impressed how well the TBI injection system itself IS not the limiting factor of the performance of these cars by a long shot.

I'm not trying to convince people that they should drop tpi for a tbi, no in fact I made my friend buy a tpi camaro because he wanted instant power. Don't f around with the intent of my post because not once did I attack tpi or push tbi over tpi. I responded to the topic of the post.

Well gee a mechanic f-ed up your car bohoo that doesn't equate to it failing on its own... I'm not waving no tbi banner, I'm making an observation based on running with a TPI all day at a track. On top of that I rechecked my latest milelage with my last highway run a day ago, I pulled 34 mpg highway AND some partial city 1 hrs worth of city driving. That 6 degree egde the tpi runs really does wonders on a tbi setup too...

The TPI doesn't have a 6 degree edge, that just happens to be the base timing. The PROM calibration holds the timing numbers and they take into consideration the base timing. So what you did was add 6* of timing everywhere in the timing calculation since you didn't program the PROM with the change. If you changed the setting in the PROM for 6* base timing and mechanically put the timing to 6* then no extra timing would have been added. Maybe the reason it ran better is because the damper has slipped and you were actually running less timing than you thought.
And you're right about one thing, you can't compare numbers from one track to another just like you can't compare dyno numbers from two different dynos. You can only compare side by side racing. But he still did beat you by two tenths. And maybe he doesn't have 20 more *peak* HP than you but he might have 20 more *average* HP than you. That might explain why you took off on him and he chased you down although you had a higher trap speed in the end. Too many factors to try and theorize what happened.

I had more I was going to say, but its kinda pointless, for the following reason and statement:

You dont really believe this statement, do you? Reread what you wrote again please, you'll find that you did. Read it more than once if you have to. I really dont care about if you attack TPI or not, it has its faults and none of which you addressed. All you did was say how bad it is and use others opinions to support your argument, none of which are facts.

in a nutshell... TBI=SLOW. if you want the car as daily driver, go for it. Otherwise... save your money for a good TPI or another car.

I guess all of us TBI owners should do that. Seems like TBI is the worst form of induction ever made. Might as well throw it all in and forget about owning a Firebird too.

Might as well buy one of those new 2002 NHRA Firebirds. Hell, who needs a crummy thirdgen TBI?

Why bother with TBI?

I'm SLOW.

Maybe I'll save up for that or one of those lightning-fast Honda what-are-they-called? NSX, yeah one of those. Nothing like having one of those. Turn traitor because I love my car?

This useless arguing only closes threads. It doesn't matter. I'm happy with what I have and have no intention of anything except making my car all that more pretty.

oh, g0d... lemme rephrase that... TBI works pretty decent on the street. Mine has great pickup and gets ~23-25 mpg to boot. TBI induction just isnt that spectacular 1/4 performance wise. Some of the cfi's do pretty well but our pickup truck gone car induction system just wont wow the crowds at the track without dumping some $$$ or getting an aftermarket induction system.

oh, and as for an acura nsx... oooohhh yeah!

Mad max,

By the way I'm running at 4200 feet altitude (if you correct for alt the time goes high 13s), I would like to see a stock TPI run faster than 15s. Again I destroy stock TPI's, I smear them on my toast in the morning!. But really this number racing were doing proves nothing, A TPI 350 with porting work, headers and exhaust, stall, stock cam would probably beat my truck.

This argument has gotten way out of hand, you came to the tbi board, not the other way around. If we had come onto the tpi board and started preaching you are well within your right to defend the good points of tpi.

So what in fact were your 1/4 mile times before the cam change?

What does an auto 305 tpi with the peanut cam and log headers run in the 1/4 mile?

Answer mid 15's. The low 15's tpi had stick and the larger cam.

What does an auto 305 tbi with the peanut cam and the log headers run?

Answer mid 16's

What can an auto with 305 tbi with the peanut cam and the log headers with the same fortifications as the tpi car run?

Mid 15's. All it took was 3.23 gears, a pulley, 6 degrees timing and ram air.

I would say that almost a second gain in time is the advantage of having 3.23 gears and a 6 * advance timing alone. What did the tpi's get from stock? 3.08 gears? Those 2.73 stock gears on a tbi are murder in the 1/4 mile.

Even you changed the cam on your car knowing full well that the peanut cam is not a performance part.

In pure stock form I had this tbi car running 40 mpg, there's no way a 350 can pull that mileage unless the gears are really low sub 3 ratio. A 350 has the same stroke as the 305 and it is a fact that a 350 will displace more air therefore more fuel than a 305 at the same RPM. RPM for RPM a 350 will make more power than a 305, at a cost of more fuel being used.

305 tpi getting 30 mpg? Really? And its pulling significantly (>0.5s) faster times to boot? I'll take that challenge anyday. From the guy that equated 0.2 sec to 20 hp that's amazing...

This has turned into a TPI/TBI War. The same stupid p!ssing and moaning the MUSTANGS do with us all. Guys, we are all F-Bodys, ok? Both the tbi and the tpi have thier advantages.

To put into perspective the REAL QUESTION on a real comparible car.
the stock89 tbi injected camaro had 20 "PEAK" hp less than a 305 tpi of that same year....important word "STOCK" This guy wants to know STOCK, when he buys the car, its probably not gonna have the exhaust, heads, intake, porting and all the other sh!t you guys are using as a basis of arguement. 20hp BOTTOM LINE STOCK, that is IT.

The TPI is more adjustible and friendly than a TBI for high performance applications, but the TBI is more foregiving on strictly "street cars" (I shouldn't have said that 'cause I'm gonna get the idiot who says "I drive my 400horse 10:1 compression Z28 to work every day" ---> Thats not a street car thats a street legal car" The intakes on the TBI are not good at breathing, I have experienced a 4,500 severe drop off in power on a stock manifold.
The tune-port is a lot more torquey like 70ft/lbs. It'll snap you back in the seat more.

Generally speaking a tune port has a lot more parts and sensors to it than a TBI and are generally harder to diagnose problems on if your not a knowledgible mechanic. You could buy a code scanner to read the codes, but that's not what we're talking about.

TBI is nice for daily driving, can be rather cheaply modded for slight hp gains, and has decent power to it.
Now if your gonna be racing this car or want high performance, go TPI.

I hope this gave you a factual look at the basic differences. I am pro TBI, but I have a great respect for the TPI too. In my experiences the TPI has been more costly for me since I have a 89 IROC 350TPI and a 92RS 350TBI ( I just swapped the old 305 for a 350) If there is anything you have questions on reguarding the two you can email meRSCamaroGuy92@yahoo.com Let me know what you decide.

Madmax, I have a 89 IROC and you are right, stock I'm be .5 tenths quicker than that at 5 degrees Celcius, I don't have a track time for 0, but I do for -4 13.89@106mph This is my ACTUAL times, not any G-Tech crap

Damm those disccusion get pretty old very quick.

Im always learning from everything is said in this board even if it look like not.

I will move from my country In December to Spain, The gas price is very high, and still Im considering having a 3th gen over there over other sport cars.

The engine is not really important, less the EFI system. (I would not go to carb with all the seassons and gas price) I dont like 4th gens looks. I would like to put a LS06 engine on my future car with time.

But for Street use I would buy TBI over TPI, As I would learn more quickly to mood it and the horse power I could get with it would be enought While I save for the LS06.

About the Look of the TPI over the TBI... that depends on pure taste I like the carburator look on those cars. But that is just me.

My Dream Would be To have a car with those lines (Camaro RS 92) very light ( at least 950kg) with something like a high reving mottor with 350-475hp, Very good suspenssion and excelent brakes. I think I can Make it happend with time and Knoweladge.

(Thanks for the Knoweladge to all thirdgen members)

Carb vs TBI vs TPI... Its just a matter of taste in a street car... on a race car you put what you can afford or the fastest thing if money allow. But How many of us have pure racing cars... That our motnhly income depend on a .5 hp difference?

RSCamaroGuy92,

Anyway is that time at 4200 feet, didn't think so. Just went to NHRAs site for time corrections http://www.gnttype.org/techarea/misc/altitude.html
and my time turns into 13.44s @ 107.6mph @0deg celcius(looks like i destroy you). Theres no way your peanut 230 horse motor could be my truck (no dyno yet but it must be very close to 400). Any way your probably driving a stick, I have auto and should have said I would destroy an auto tpi. Also I'm not here to run anybody down at all, I just wanted to make the point that a TBI in a 4200 pound truck can be made to beat a stock tpi setup in a 3000 pound car. I said this because tbi seems to have this rep of being allright but not really capable of going over 300horse.

alright... getting back to the topic at hand, which is this guy wanting to buy a tbi... I d say go with an L98. My reason is this: Lets face it, most of us dont have loads of time or money to sink into our cars. I dont... if i could do it over again i wouldve just gone and bought a 350 TPI... plain and simple. I didnt know how slow the tbi cars where in the stock form when i purchased mine. My only saving grace is that i paid 1800 dollars so even with a new motor im still below 3500 dollars which isnt too bad, considering that i have a semi-decent car that fulfilled my goal of having a sporty daily driver with a V8. If you dont want lightning performance then the tbi isnt bad. Its reliable, gets good gas milage, easy to work on, and, above all, its simple. A tbi'd camaro offeres a good sporty alternative to all those booring budget 4 and 6-cyl. cars. Can a tbi be made to perform, you bet... But you can get more by jsut buying a tpi and working with that. All the induction systems have their merits, as well as drawbacks and you have to work with each system accordingly.

well after reading all of that im gonna have to say screw making any kind of decision about what i want before i buy. im just gonna buy a thirg gen when i find a deal. i dont care what engine(well not a V6). Finding one here just isnt happening... =(

be careful and do some reaserch on the car your gonna buy. MAke sure its not salvaged or anything like that. The one i have went for an off road excursion witht he previous owner that cost it its fenders and messed up the front nose and gfx.

That's all that matters. Just get a V-8 with a decent running engine thats to your looking. A camaro is a camaro, a firebird is a firebird, wheather it be carbed, tbi or tpi. It still will be a fast fun car to drive, and in my opinion look good too. That's all that matters, wheather your happy with what you get. Its all good, its all american, and face it, its not a FORD, haha.
Good luck to you man.

:lala: :hail: :hail: AMEN ! :hail: :hail: :lala:

Look at it like this:

A STOCK TPI305 will be slight;y faster than a TBI305.
BUT the TPI305 has better heads and cam.
IF you put the TPI305's heads and cam into the TBI305, the TBI305 will have very similar power.

TBI is cheaper then TPI when it comes to mods and matainance. Trust me, I KNOW, I have BOTH! My RS has a TBI305 and my GTA has a TPI350.

They are both good systems.

The problem with the TBI cars is not the TBI itself, only what's it's on top of and the exhaust system it's stuck with.

So there, it's all said and done! No more arguing, it's giving me a headache!

If you call 17 hp and 70 rwtq similar power then I guess you are right.
