I think you just answered your own question.

Benm109

Yeah, yeah. I know.

Not everybody's looking for all-out performance in their cars, though. Flame me if you want, but I'm actually having fun with my little 305. It takes to mods just like any other V8 and is pretty easy to work on. I know it will never be considered "fast", but at least it won't be as slow as stock.


All that aside, I've got other projects in mind for a real HP/TQ monster.

RS1992

Nothing exactly is wrong with it. I am going to give it a full tune up tonight. The only thing that I can think of that is of any concern is the high idle, but I do have some vacuum lines loose and the heater core hoses off right now.

What do u have done to your 305, benm109?

Purple 92 SS

well life with a 305 is new to me too..

I know that the car is a dang on turd when it comes to speed though.. Ive driven faster 4 cyls.

What mods can be done to 305's that wont kill gas milage, but will at least perk it up a good bit.. Im not looking for an all out horsepower beast, cause Ive got that in my 92, and my 01 ls1, but i'd like to be able to at least get off the line faster than a 1972 VW Beetle.

Besides exhaust of course and removing smog..

Benm109

Sounds like you've got the right plan. Do a full tune-up, look for anything hacked or disconnected while your at it and fix any problem you find, drive the car around for a while and then go from there. Always start with easy stuff first.

Anyway, as far as the mods on my motor, I really haven't done too many performance mods, yet. It took me a while to get all the problems and bugs figured out. So far, I have:

-14"X3" open element air cleaner w/K+N air filter
-Ultimate TBI mods (basically it's like porting the TBI unit)
-Adjustable fuel pressure regulator
-Edelbrock Performer TBI intake manifold
-Flowmaster muffler

That's about it motor-wise. I've been working on the drivetrain, suspension, and chassis so engine mods were put on the "back burner" for a while. Next mod is full exhaust. 1 5/8" headers (ceramic coated), 3" y-pipe, 3' test pipe, 3" cat-back. I'll have this done in a couple of months, and this is going to be the best mod yet.


Well, if you want to keep good gas mileage but pep the motor up some, this is what I would recommend:

-Open element air cleaner or a custom CAI: No one makes cold air kits for our cars, but there are plenty of options out there for some awesome setups.
-Ultimate TBI mods: Just helps the engine breathe a little easier. It also makes the stock FPR adjustable, which helps out a lot. I'd also suggest adding an injector spacer while your doing the ultimate TBI mods [Jegs, TurboCity, and XtremeFI (on Ebay) sell TBI injector spacers].
-Full exhaust: Headers with a matching y-pipe, a test pipe or high flow cat, and a 3" catback. Exhaust is the worst restriction on these cars.
-1.6 roller rockers: Increases the lift of the stock cam and is a pretty cheap mod. Well under $100 for stamped steel 1.6s.
-TBI intake manifold: The stock manifold is supposedly restrictive, but I'm not 100% sure on that. Anyway, Edelbrock, Holley, and GM Performance Parts all make TBI intake manifolds, but the Edelbrock is the only direct-replacement. Of course, you can also just put a carb intake of your choice on and slap a TBI adapter plate on it.
-Camshaft: There are a lot of good roller cams out there, and a lot of them will supposedly work with the stock computer. Although, considering you still want decent gas mileage, I would suggest just sticking with the stock heads/cam, especially if your not interested in burning your own custom PROM/chips.

That's all I can think of at the moment, but I'm sure I'm forgetting some mods. And, of course, there's other mods that help wake up these 305s that aren't motor-related, like shift kits, better gears like 3.23s or 3.42s, etc.


Of course, there's also nitrous.

Purple 92 SS

Ben,

So far Ive done the following since I posted origionally.

Open Air Cleaner by Edlebrock, havent gotten the K&N yet, but its on the list.
De-smogged.. no more pump, and even unbolted the lines from the manifolds and plugged them.

New Bluestreak Cap & Rotor Button Kit.
New AC Delco Coil.
New upper Radiator Hose
New Heater Hoses.
Autometer Silver Tach 5"
Undercar Neon
MP3 Player
Seat Covers
Re-Mounted rear spoiler.

And Im wetsanding the body to get out most imperfections.

Things to do still that I have just havent had time to do:

PLugs, ACCELL 8.8 Wires, Thermostat 160*


So HP Wise I havent done much yet.


I definately want a Flowmaster, with 4th gen chrome tips.. I think the square look will go well with the back end.. I dont want it loud though unless I jump on it.. cause the purple car has liek a 1 chamber on her, and is like a baby nascar when I start it. People at the other end of the neighborhood have actually told me theyve heard me fire it up when I do...

THe Edlebrock Intake sounds like a plan too.. ive priced it at like 229.00 so thats not too bad.

What is the benefit of the injector spacer? can I do it without the Ultimate TBI Mods? Im a little leery on porting still.

As for the rest of the exhaust.. ive had some issues with the headers on 2 fbods now.. my purple car has cheapo flow-techs,and im not impressed.. the edlebrocks that we used on a buddys gta sucked too.. entirely too hard to work with... I dont know if they were meant for an 82-92 camaro/firebird though. Ill have to research the header option alot before I do anything of that nature to the car. As for size of pipe, Ive got 3inch on the 92, and it seems to do well, but I dont know if that much will be necessary.. Ill probably go 3 inch just to do it anyways, but either way, its a while down the road thats for sure.


Is there that much gain from 1.6 Roller rockers? if so, im in, but if not, then I'ts gonna be somethign down the road from now.

Cam and heads will probably stay for now.. if not forever, I dont know. Im not really wanting to tear into this motor unless I have to.. it seems to run well.. but if I do have to go into it, you'd better believe itll not be stock, if I even keep it the motor in the car.. I do lust after doing an LS1 conversion in a 3rd gen like everyone else.


The Ultimate TBI Mods interest me, but like I said Im nevous on porting anything. How hard is it? how long does it take ? etc.

thanks.
-steve

Benm109

Took the words right out of my mouth. I've had some 4th gen-style stainless steel tips just sitting in my garage for the past year just waiting to go on. Hopefully I can finally put them on when I get a new catback in the next month or so.

The ultimate TBI mods are actually pretty easy. It took me about an afternoon with a dremel tool and sandpaper to do it. I've actually been meaning to do a write-up with pictures of how to do the ultimate TBI mods for a while now, but I've been slacking off on it. I've got 2 complete spare TBI units just waiting for some porting. But, you can do without the ultimate TBI mods. Doing those mods are just to help get every bit of airflow that you can out of the TBI unit, but it's not really necessary unless you've swapped heads/cam or a bigger motor. I would suggest an adjustable fuel pressure regulator though, by either modifying the stock one or buying an aftermarket adjustable one. It just helps fine tune the car a little.

The injector spacer just spaces the injectors up more, of course. It allows more airflow to come in through the sides of the whole TBI unit. I would definitely recommend an injector spacer, though. It's really easy to install, you don't even have to unbolt the whole TBI unit, just the injector pod. And they're really cheap, $10 on Ebay and $20 at Jegs.

They also make throttle body spacers for TBIs, just like most other FI vehicles, but I would not recommend one. If it's thicker than 1/2" (which most are), you will run into throttle cable and TV cable problems. Sometimes the fuel lines will not want to thread in anymore, either. All sorts of little problems come up and it's just not worth the trouble.

I've heard some very good things about certain Hedman headers and Hooker headers. Hooker headers seem to be the most popular choice on the Exhaust board, especially the 2055s. They are 1 5/8" shorty headers with a 3" y-pipe included. Match that up with a 3" test pipe or high-flow cat of your choice, and a 3" catback, and you will be good to go.

I'll be able to tell you just how good, or bad, they are in about a month or 2.

Honestly, you won't gain a lot, I've seen dyno results of between 10-15 HP on a basically stock 305 TBI. It's not much, but it's still a gain, and it's not that expensive. You can get 1.6 stamped steel rockers for about $60. Even roller tip rockers go for as low as $100.



Also, as you've probably figured out, I'm changing out the entire exhaust system on my car in the next month. If you want, I can post my experiences and thoughts on it. I'm installing some brand new, ceramic coated Hooker 2055 headers (with AIR tubes cut off and holes welded shut), 3" test pipe (until I can find a good high-flow cat), and Hooker 16823 3" Aerochamber catback exhaust system. Right now the car has an all-stock exhaust except for a Flowmaster muffler and tips. It sounds pretty good, but I'm getting tired of the "drone" of the Flowmaster, and the fact that I sound like every other truck around here with a Flowmaster on it. I can also post before and after sound clips and videos.

Purple 92 SS

Yea, thats what i'd like to do for mine. Where'd you get your tips and how much were they? I wonder how expensive they'd be for me.

I think ill be a smart *** and wait for you to do the write up that way Ill not get in over my head. Im just now getting used to the idea of polishing wheels, so internal parts done by me to my motor will wait a bit i think Besides, im not going with heads/cam or bigger motor yet on this one.. how do you tune your fuel pressure regulator? how do you modify the one youve got? I thought the amount of fuel was computerized to an extent..


Now, that sounds liek a better deal there. quick and easy.. im in.. just gotta get off my **** and buy it. Does summit carry them? i was going to order a pillar pod for my guages so I guess I could do both at once.

Yea, if its that much trouble, I think ill go with your advice and say its not worth the trouble.

That sounds like a good setup. Hooker seems to be a good one overall from waht Ive heard. I guess I should spend more time on the exhaust board!

Sounds good. I look forward to it.

10-15 hp for under 100 bucks is not too bad in reality. I may just have to do that. Have you done it yet? anything to make this thing get up a bit better. she's a bit lathargic.

yea, Im very interested in this. I'd really prefer to find the equivilant of the 2055's without the air tubes having to be welded off though. I wonder if they make them. If so I may get those then. I do agree ceramic is the way to go though.

I dont mind the drone of a flowmaster, especially since in this thing there is no drone at all.. *** i miss some noise.. even my stock ls1 z28 is louder than my 89. its SUPER quiet.

I look forward to hearing the clips and finding out your successes with the new exhaust setup.

-steve

Benm109

I got mine from a friend with a 4th gen (97 Z28). He went to true duals with turndowns so he didn't need them. I bought them for $50, and started to polish them, but never finished. I've seen many companies sell new stainless rectangular exhaust tips for $100.

You are correct, the computer does adjust for the amount of fuel per say, but you can still kinda tweak the fuel pressure for wherever you want it. To modify the one you have, all you have to do pretty much is just take it off of the back of the injector pod, drill out the center weld in it, cut a slot in the head of the screw, and then reinstall it. It doesn't really make a lot of sense though unless you can look at one and see what I'm talking about.

Exactly how to modify the stock fuel pressure regulator is detailed pretty well in the one of the ultimate TBI mods tech articles, I think it's the second one.

No, they don't. Jegs is the only large supplier that sells them, and it's under there own name of parts. The only 3 places that I know of that sell them are XtremeFI (on Ebay), Jegs, and TurboCity (they want $30 though )

No, I have not done this yet. And honestly it will probably be a while until I get around to doing it, too. After swapping out all the exhaust, I think I'm going to be done with the motor for a while. I'm really wanting to lower the car soon, first.

Hooker does make some headers that are very similar to the 2055s, the 2460s, but there is a catch. They are still 1 5/8" shorty headers, no AIR tubes, with a 3" collector, but no y-pipe is included. For a while Hooker never even made a y-pipe for the 2460s, but now they do (part number 16767 I think, I'll double-check). Problem is, it necks down to a 2.5" y-pipe, which sucks. It wouldn't be too hard to just cut the 2.5" pipe off and get a 3" pipe put in.

It's really a toss up. You either have to cut/modify the y-pipe with the 2460s (or have a totally custom y-pipe made), or cut and weld the AIR tubes on the 2055s. I did alot of research between the 2 headers, and I personally decided it was easier to just cut off and weld the AIR tube holes shut.

Me too. I've been wanting to do full exhaust for so long now on this car, and it should really wake it up performance-wise. I'm not sure how my wallets going to feel though, I'm ordering over $800 of stuff from Summit on Saturday, and that's not even everything I need/want. It will all be worth it in the end though:

Benm109

Just a little update, I got the parts from Summit Racing in on Tuesday. Everything is coming together very nicely! The Hooker headers look pretty good right out of the box, but I've already started modifying them, cutting off the AIR tubes and opening up the collectors on them a little bit. The Hooker catback is awesome. Full 3" mandrel bent pipe to the muffler and dual 2.5" tips out. Best part is that the 4th gen tips fit perfectly on them, too. Although I have to admit, dual duals wouldn't look too bad either.

No pics just yet, I need to find my digital camera first.

RS1992

I just ordered a crate engine from summit and charged it to your account, if thats ok with you.

Purple 92 SS

cool... sounds great. you got the ceramic coated headers or no? cause that's what I'd want if i were to run with them. of course, then I'd have to send them back out to have them re-coated due to the fact that I'd cut off the tubes and re-welded but oh well.

-steve

Benm109

That's exactly what I'm doing. Since I knew I was going to modify them, I just ordered them uncoated. Once I'm done, I'm sending them to a TGO board member (TPI383 has his own coating business, www.cecoatings.com ) to be ceramic coated. I've also heard some mixed reviews about the ceramic coating that Hooker offers on it's own headers.

Purple 92 SS

oh cool.. well then it may be worht it for me to go that route then.

Lemme know how the whole bolt up goes on the car, cause thats the part i'd hate if it was a big pain..

I am in Pickens and currently trying to restore a 91 GTA When finished I would love to cruise.

cool, i myself just got done rebuilding my buddy's 88 GTA 305tpi.. its a pretty good running car. Now, we also put all sorts of spohn **** in it too.. sooo..

a cruise would rock.

RS1992

I PM'ed you , I need to talk to you about my POS, lol.

fast82-Z28

i bet thats gonna sound good man!!! i'll be lloking for some good times at greer thurs. night!!!!!

they may not show much difference on the TBI 305s, but the 1.6 rockers(even the stamped steel cheapos) make a major difference IMO....i installed that and a jet stage 2 chip on a friend's car and he gained almost 4 tenths!

Purple 92 SS

yea, now i gots to do the 1.6's if it makes that much difference for that cheap.. i dont see how I couldnt do it. anyone know any factory cars that come with 1.6 rockers stock? cause then I can get em cheaper through my second job.

I wrote you back, and left my number. look to hear from you soon.

-steve

Benm109

It better sound good! I've said it before, but I am just sick and tired of that Flowmaster "drone" when cruising. Not all cars with Flows drone, but mine sure does.

I'll definitely be a Greer (drag strip) sometime soon running the car. I'm probably going to need some pointers on how to launch beforehand, though.

I wouldn't be surprised if GM put 1.6 rockers on SBCs from the factory at some point, but I honestly have no idea what cars it would be if that's true, LOL.

Purple 92 SS

yea, well alot of my projects are on hold now.

I jsut got my vert kinfed this past saturday morning.. they cut the top and stole the CD player out of it.. and then stole the CD player out of my truck. Im a bit pissed about the whole thing now..

-steve

Benm109

Wow, I really don't know what to say.

That's just totally wrong. It's one thing to just steal a CD player, but to cut the top on a convertible... I've never even thought about how vulernable verts with ragtops could be.

All I can really think of to say is sorry man.

xcelreate2maro

well i gess ill post some too...my old name was Xceleratemaro i have been around for a wile...and helped many member do all sort's of thing's just hit me up if i can help a cruse would be cool..im trying real hard to get my pos on the road ,,well see..later Chris ps this is a old pic i have a lot more done now..

Purple 92 SS

i appreciate it .. I just am more pissed at knifing the top than anything else. really.. that just pisses me off. ugh.

what all else you got done xcellerate?

Purple 92 SS

yea, thats what ive been saying for a while now. I jsut dont know why no one has organized a SC upstate or sc midlands F-body club.

mustangs get all the cool clubs.
-steve

Benm109

Look what I found, Federal Mogul makes 1.6 rockers. They're not roller rockers, but they'll still work. You can get them through SDPC:
http://www.sdpc2000.com/catalog/1956...Arms-87-UP.htm

Or you can get them through a regular auto parts store. Here they are on PartsAmerica.com:
http://www.partsamerica.com/ProductL...tnumber=r1023r


If I can scrounge up enough money, after this large dent in funds from the exhaust, I'm going to throw those 1.6 rockers on while installing the new exhaust. We'll see though.

Purple 92 SS

well according to that Sdpc company the title says 1.6, but the description says federal mogul 1.5's so i wonder which is which.



hmm. if thats really a 1.6 though im gonna order them myself.
-steve

what about them?

Yeah, who are they? Id be interested in finding out some info.

South carolina f and y body...SCFYB.com

Purple 92 SS

I know what they are and ahve been a member for many years now, but they aren't a club, they are an "internet presence"

not to mentino they tend to be a bit cliqueish from my experiences, and arent strictly F-body related.

Before i had purchased my 01 z in 2003, I felt that i was the odd man out cause i had a third gen, and wasnt an owner of the almighty "LS1" car.

What i want is a true local Fbody club, like the vettes have here.. Capital City Corvette Club.. all vettes, all seem to get along well, all have fun, throw carshows, show up to meetings, and cruise ins, and shows, and what not..

Why arent there any good F-body specific clubs in SC?

GTA_JOE

Why don't we just start one ourselves? All we have to do is find a meeting place and start meeting once a month or every few weeks until we get enough of a turnout to take it to the next step.

nemanracing

I just moved out here from so-cal, i live in the lancaster area, In Cali i started a domestic muscle car club and did fairly well, we meet up every two weeks, went to the tracks once a month and had a cruise once a month, I would be interested in starting/helping with starting a similar type club out here...

85LT4Z28

hey just moved out here want to meet other 3rd genners out in the sc live in lancaster... came from cali as well as nemanracing... so hoping to meet some cool people

Purple 92 SS

well i founded and have been president of ground zero car club long before my fettish with camaros emerged... The club is a club for all cars and trucks and bikes and everything, but as ive grown older ive found that im really focusing more on the camaro. Its where my interests are.

I'd be interested in being part of a club for F-bodies, and definately would show up to meetings and the like if at all possible, but problems i have are : 1, i work 2 jobs, 2 im married and would want wifey to come with me, 3 dont think i'd really wanna be a figure head in the club. I'd more wanna be a member than a leader at least for now. Just getting people involved is the hardest part, and then, keeping the BS "highschool" mentality out of it. i'd want it to be a family oriented thing, without the backstabbing and bull that everythign else seems to incorporate with it.. if you follow me.

-steve

Superior Being

I'll be getting a 3rd gen camaro tomorrow and yeah it's my first post! Looking forward to getting to know you guys.

Oh yeah, I live in north east Columbia and am currently attending/living in Clemson.

MrDude_1

heh, when you only go online, they are just a internet presence.. lol.

but take the lowcountry crew, specificly charleston like he was refering to.

we all get along like a car club.
we all goto the track like a car club
we have regular meetings that people attend year round, rain or shine... where we all cruise and grab something to eat.
we have dyno days
we attend car shows.
98% of us drive fbodies...


sure the columbia area, upstate, and basicly the entire rest of the state suck...
but its not our fault.. its YOURS. you live there. go do something yourself.

theres noone saying we have to do any of thoes things... but people set them up and we make stuff happen.
go on the board, and make it happen, or dont complain that its not there.
its like you want someone to make a club your way for you.. lol.

no offence, just my perspective..

Purple 92 SS

first and foremost.. No offence taken.
What you list the lowcountry crew doing sounds fun. It also sounds like a real club. That is NOT what we have in columbia by any means. *** knows I wish we did. At first, back in say 03 when i first started hanging out with the FYB down in five points it was cool.. but then we all got kicked out of there by the cops, and now no one hangs out.

Saying that its "our" fault is true to an extent. but to another it is not. Ive ran a car club for over 11 years now. almost 12.. im tired of having to organize everything.. lets face facts anyone who has ever ran a club knows it is a truely thankless job.... that being said, along with my experience with organizing and running other clubs and functions, plus working 2 jobs, etc etc etc, gives me relatively little free time to plan / organize for anything else. SO yes, Im complaining about not having a good F-body club, and yes, Im complaining about not having meetings, and yes, im complaining about not doing all the cool things you guys do, but in the same breath, I just dont have the time to do that type of Organizational tasks. I can, at most, show up when something is planned as long as i have long enough in advance to request it off. Which is what I try to do now with my other clubs and what not. Another problem is getting people to be comfortable together. to know each other, online is one thing, but personalities are not always what they are online in person.. as Im sure we have all found out one time or another.

I dont really follow you when you say make a club your way for you.. I was expressing my desire for a F-body club, and not just an internet presence. A club that does the things that seemingly your low country division of the F&Y body organization does for you all. That takes as you said "people" to "set it up" I dont know if columbia has people too busy, not interested, or what, but that doesnt happen here in columbia.. When it did, it was folks with other cars, not just fbodies. My statements were for an F-body club ONLY. No Y bodys, no J bodys, no Mustangs, Imports, or trucks, which appearntly the FYB seems to have alot of on there... or in the very least has alot of folks signed up with.

Not to mention that since the FYB is just an internet presence, there are no scheduled meetings, no events, no car shows thrown, etc. etc. Hell at last years F-body gathering, there were more in the club that I went with then showed with the SCFYB.. and we only had 9 cars.. And the year before that the FYB had one of the largest showings of clubs there.. what happened? Without a form of management, even if it was regional to the midlands, the club falls apart. (keep in mind the gathering wouldnt register you as SCFYB lowcountry, that was STATE WIDE)

Another issue that we've had as Fbody owners, is that poeple are not as interested in new fbodys, as there are NONE. So its hard to keep that interest up with the younger crowd if we dont have a new car design to tout to the masses. (even though this problem will be remedy'ed on 1/9/06) I think also another problem we have in Columbia, Is that alot of our members are Military Active Duty. While this is an admirable job, and I thank each person who serves, it doesnt help to club functions when half the "club" is deployed overseas Which happens to happen a lot it appears.)

I think in the end there is no easy answer about it. Some areas / regions are just better than others for different types of car clubs. Mustangs, just seem to be the golden child, next to corvettes, for car clubs... or at least in the columbia area they are.


I dont knwo what im asking, all i know is that i really think it is a shame that we, as the #3 most recognized GM brand name(camaro) are unable to have locallized F-body clubs that are strong presences and actually do things together.

Such is some of my thoughts... .and Like you, I hope, no offense to my thoughts.

Superior Being

So I'm having a little timing problem and getting a little back firing up the throttle body on my 88 when i give it just barely more gas than what is needed for very slow acceleration. Is there anybody near north east columbia that might be able to help me out tomorrow...the 4th? Otherwise i'll have to take it over to the shop and get it checked out when i get my alignment before I go back up to clemson friday. considering i haven't worked since last summer and i won't be working for another week i'm hoping not to have to have a shop do this.

nemanracing

I thought all 88's where fuel injected(MPI,TBI,TPI) is this a non-stock motor?

Also for those interested i posted a thread about the club on here https://www.thirdgen.org/techbb2/sho...hreadid=338799

yeah, i thought about it when i wrote it but i didn't go back and fix it. it's a stock tbi.

fixed it...
