Hey. I got a 305tbi and have a goal of just 300hp (crank). can that be done with just bolt ons?

Yes..




Hey, it's technically a bolt on.

But really, just find yourself a decent 350. Or drop in an LT1 or LS1.

CM Engines has a nice 9.0:1 compression pump gas-friendly 350, 325 HP street engine for just over $3,000.

Where does bolt-on stop for you?

For 300 hp without nitrous, and keeping the TBI unit you´ll need to replace quite a few parts.

You will not get there without replacing the stock camshaft, stock ECM, stock fuel pump and stock fuel regulator, so these will all have to go.

Apart from that consider heads. Porting might do although I´m not 100% certain they will get you any further then 300 however. But swapping for different heads makes the job far easier.

Also, intake, exhaust, some kind of cold air induction, be it cowl or some ram air kind of setup helps.

The usual I´d say. Just read the stickies and learn.
In the end you will have spent the mentioned $3000 you would also have spent on a new engine I guess.

yes it can be done

camaronewbie

Yes, but not without heads and MAJOR chip modifications. To me, not worth the trouble on a 305 - for the cost of the bolt-ons and trouble, you could do an LS1 swap!

Dougie91

Just sucks I can't use what I got and not spend a fortune lol. I just want my bird to have in the 300s and not spend mad $$$

Well do you have a goal E.t. wise? Or you just want the car to feel better?

Dougie91

Id love to beat my friends stock 05 mustang gt

camaronewbie

Yeah, it does suck. It's hard to double your hp without spending big bucks for anyone. 305TBI has 170hp stock, 300 is almost double!

But, until you get the big bucks, take solace in the fact that 1) the car still looks cool, 2) if you go too fast we can't see how cool the car is, 3) your getting 30mpg (Honda mileage) when gas prices are closing in on $4 a gallon!

I might have 300hp (I doubt it), but I have to run 93 octaneand I only get 17mpg. It's not often I ever 'open her up' anymore with gas prices the way they are. Just keep reminding yourself that big hp numbers are a compensation for 'smallness' in "other areas" - it's not necessarily true, but it works for me

Any pencil-***** can buy a Mustang! Takes REAL kahones to drive a F-body!

Dougie91

Well wouldd a lightly modded 350tbi make that?

UnderCover89TBI

iTrader: (25)

to be an 05 4.6 2 valve mustang? 350 tbi, heads, cam, headers, chip tuning, upgraded tbi, upgraded fuel system, 3.42 gears, nice stall converter. you can do some weight reduction steps and may be close!

thomas1976

Sounds like a 300rwhp 350TBI engine.

Dougie91

Yeah annd like 6 grand lol

torque_is_good

05 is when the 3 valve came out. if it's an automatic then he put down about 240-250 RWHP stock. A manny tranny put down about 265 RWHP stock.

your 3rd gen, even with the 350 tpi isn't going to run with the S197 unless it has a cam change and all of the bolt ons. My 4th Gen LT1 with long tubes, 93 octane tune, CAI, 3.23:1 and 1.6 rr's beats my 07 stang from the dig (when it hooks) but it can't pull on it once we're rolling.

stang- CAI/tune/axle backs

camaronewbie

Nah. Should get a 350 TBI motor cheap from a wrecked truck/van/Caprice (like $1000 max and that's for the entire wrecked vehicle). Cam not too expensive. $300 headers/Ypipe, $100 fuel pump, $300 stall. Then swap in a $300 4th gen rear with 3.42 posi and LS1 brakes, and your set. Maybe $2500 max assuming you do the work.

But ... LS1 can be had almost as cheaply. Have larger install cost (headers, etc.), but that'll EASILY spank Mustangs. Should be able to find a complete wrecked 1998+ f-body for $2000 easy! Hell, my 1997 Z28 not wrecked with only 95,000 miles on it I only paid $2800 for, and that was 3 years ago!

so it sounds good then huh? haha.

thomas1976

Yes it sounds good, with some properly matching aftermarket parts, 350-400rwhp 350 TBI should be possible too.

So, I'm a pencil-***** with REAL kahones...?

Yeah, the one mentioned, a stock 05-10 3V 4.6. Question though, how many bone stock Mustangs are left out there? Especially my generation of Mustang, the 99-04 GT. I bought my '01 GT in great condition, with leather interior, 5 speed, 3.73 gears, less than 100,000 miles, for only 6,200. Pretty soon, I'm going to have more in mods than what I paid for the car.

Just this weekend I dropped about $2,200 on my built T56 with a 26 spline input shaft, billet keys, carbon synchros, plus a Fidanza flywheel, Centerforce DFX clutch, 03-04 Cobra aluminum driveshaft, Steeda Tri Ax shifter. Know what's coming this winter? On 3 Performance single turbo build. They have made 440 RWHP 496 RWTQ on an otherwise completely STOCK, stock internal 2002 GT. Needless to say, 400+ RWHP and nearly 500 RWTQ backed by a 6 speed, and 3.73 gears would be VERY tough to beat.

I absolutely love my Camaro, and Mustang, but you're way too obsessed with talking smack on them. A place called Modular Mustang Racing sells a 4 valve longblock which uses a factory 03-04 Cobra block, know what block that is? The Romeo block, I.e. the same exact iron block used in the late '01-'04 GT's, after the switch from the earlier Windsor blocks. They can handle 1,000+ HP. The internals, what the heads will flow, and the drivetrain are my only issue.

You're giving him a plan to beat a stock, auto '05 GT. Think about the other ones out there. Single turbo, Vortech and Procharged Mustangs, or even Hitech stage 2 cammed 2V GT's. All capable of low 12's with the right suspension, traction, and a good driver.

They're all good platforms. Whether it be an old school 2 piece RMS 350 small block such as what I'm running in the IROC, an LS1, something more modern such an as LS3, or a Romeo or Teksid block out of a Mustang. I know of a stock aluminum Teksid block Mustang that made 2,000 RWHP. Can't even say that for an LS1, without it being a pricey Darton sleeved block.

And since when does it take real kahones to drive a car with only 170 horsepower? A new Civic Si puts down almost 200, my Mustang in stock form made nearly 100 more horses than that, and over 300 LB-FT. Whole lot newer of a car, but this isn't the 80's or 90's anymore, and of course you could use the LS1 as an example, but it's not the car in this scenario.

We just dont like mustangs. And the new mustang engines 4.6 3 valves cant handle that much power. Car craft did a story on them a few months back. Anyway we will stay 3rd gen related. 13 second cars arent fast anymore. You wanna keep up with cars you need to run high 12's. If you want to be able to beat most street cars you need to be in the 11's.

"We"

Are you aware that there are a few members that also own Mustangs? I love this site, and most of the knowledgeable people on it, but it's people like you and camaronewbie that disgust me on here.

So high and mighty with your sub 200 horsepower third gens, and anything else is crap. Get real. If it weren't for the Mustang, GM wouldn't have the idea of the pony car to copy in the first place. I can understand wanting to beat one just in the name of some competition, or just being more of a Camaro guy, but it's just petty BS that I've seen on here lately. Everything is about insulting Mustang owners, name calling, how easily they can supposedly be beaten, etc.. Funny thing is, I don't even see much about Camaros or Firebirds on the various Mustang forums I'm on. They don't really care to be honest.

The attitude on here as of late is starting to remind me of some reject in a Civic, acting as if they have something to prove to the V8 world. Gives me a good laugh how a guy wanting good power out of a 305 to have some fun up against a friend's '05 GT turned into insulting the owners of Mustangs.

Seriously though, this self confidence issue and/or underdog attitude towards Mustangs, it's pathetic. I won't even comment on your theory that the 3 valve can't handle much power, that's funny.

BTW, the 3 valve 4.6 has been gone for almost 2 model years now. The 2012 5.0 DOHC 4V GT is coming out in a matter of months, making it two model years with the new 400+ HP 5.0.

As for your buddy's comment of any pencil ***** being able to buy a Mustang, this one is being built. Drivetrain is almost completely revamped, from the flywheel back to the driveshaft, including the 26 spline T56.

Eventually after my turbo build, and I want to run a little more boost, I'll pick up an 03-04 Cobra longblock. There are turbo 03-04 Cobras that have trapped 140+ on the stock longblock. I'll always have tons of love for Camaros since it came before my Mustang though, so don't get upset over it. I promise I'll neglect the Mustang at some point to put some cash into the IROC, since apparently everyone here dislikes Rustangs.

lol sorry man not trying to insult you one bit. I know the 4.6 3 valve has been gone but an 07 and newer is considered new for me. My first love is Dodge and my Dodge Charger so I know how you feel about your mustang. It's okay. It's just my personal preference to not like one. And we were telling the guy one how to beat his friends mustang that is somewhat stock, not all mustangs.

I should have actually learned my lesson by now. Before ninetyone and I spoke on a friendly basis, he swore his L98 could take a 99-04 GT, that's actually what lead to us meeting up and doing a couple quick roll races.

Not taking anything away from his car since it is pretty quick, but he just couldn't stay with me in a 50-120+ roll. Sidenote: We were both limited to a roll race. My stock TR3650 5 speed had a bent shift fork, pretty much destroyed shift keys, and synchros. I only had use of 1st, 3rd, 4th, and 5th. But that is all taken care of now, with the T56. He showed some good sportsmanship about it too, no negative comments towards Mustangs or their owners, such as someone else.

Matter of fact, this PM from that night when we got back is why he has my respect.

"good run dude! Your stang is pretty bad-***. Maybe we'll meet up again after i change my trans out and get 342's."

Anyhow, I'll end this subject, and continue to enjoy owning and liking both cars. Not being a one brand fanboy. And on another sidenote, I like Dodges too. I'm considering either a Ram 2500 Cummins next, or an SUV of some sort. Maybe an '02-'06 Escalade since they've come down in price majorly.

Right now I'm daily driving the Mustang. At least the gas mileage is awesome for having 3.73 gears, but I want to it to be a weekend or good weather only car. So, time for another addition to the fleet.

Wasn't even mainly towards you.

More or less the one who told me I'm a pencil-***** with REAL kahones, seeing as any pencil-***** can buy a Mustang, and it takes REAL kahones to drive an F body.

It is possible and I would do something like what they did just keep TBI and use hydraulic cam but I like high reving engines
