Recently there was a club started at my school for people who enjoy street racing. The only qualifications are that you must have bought your car and mod your car with your own money (no financial help from parents or anyone). Anyways, right now at the top of the food chain is an Acura Integra VTEC 5 speed. I have a practically bone stock 1986 Firebird 305ci auto LG4. Will he completely embarrass me? or will i give him a good run. if he is going to embarrass me, what should i mod to my car to give him a run?

if your fully stock I would think the integra would prolly win but it should be a fairly decent race

there are some things you can do though that should help you out a big like getting a header, catback, slightly larger cam (don't want to go too big cause the stock heads) just as some basic things

I'm sure though that other ppl would be willing to give you some input as well

BigErns90IrocZ

Hmm do what RX7 said, that should help a bit. I think you might be able to squeeze an LT1 cam in an LG4, not sure though. I would say that the Type R would be landing low 15's or so. Mid's if the kid is not that great of a driver.

I would say get exhaust, headers, and a cam, not sure on the cam though. I am not an expert on the carbed F-bodies so input from someone with more knowledge would help.

He would rape you on the highway cause of the V-TEC, but stoplight to stoplight, or roughly 60 mph you should take him if it is from a stop, and the kid probally wont do a 3k drop. I saw a turbo Caravan(minivan) pull on a stock Integra Type R at the track, held him up till about 65 or so. The Integra only won by half a car or so, ran a 14.97 to the Caravan's 15.2 or so.

the biggest reason I wouldn't go with a larger cam on the stock hds is due to there flow ,or lack thereof, if you st art getting into larger lifts the air flow could and would reduce and you would lose performance,

plus with everything else being stock just a mild hop up cam should work great


I would say nothing more then maybe 212* @.050

but again listen to other people here on this being that they prolly know a little more

I raced an Acura Integra VTEC. Wasnt a Type R, but had Vtec stickers all over it. Raced it with a 1986 Camaro 305. Stock except an edelbrock LG4 cam [cam spec's 194 214 .398 .442] and Accel Super coil. Took him off the line for about 30ft then he started catching up. His nose got to about the back of my door when we matched out. Stayed matched untill he appeared to of hit his govener as he just stopped acelerating quite suddenly but didnt slow down. So i eased back to play abit. Now i have beat some other LG4 cars with that car but never tracked it. So u should be able to give him a decent run if your car's running good and with a few small upgrades.

Your stock LG4 cam is 177 194 .350 .385

I raced a m8's Type R with my 1992 5-Speed G92 and it couldnt really be called a race. But he did take me off the jump, was too busy showing off my tire spinning abilities. He kept telling me he could smoke any 305 camaro so i finaly lined him, he now knows better. He gives me the "Wait till i get my Turbo" line now.

rx7speed

read the sig and wait till I get mine

lg4's are the quickest trust me i know, i had one. but you can give some cars a run for their money. does he have any mod's done to his car, if so it's gonna be a raping but if not it would be semi close maybe, stoplight to stoplight. but like everybody else said headers, catback, and a very mild cam on stock heads would have a nice seat of the pants difference, you wouldn't be runnin with lt1's or anything but you could probably take this kid. good luck

one more thing, if your stock when you race, if you do, dont put money on it. unless your just a rich kid who like's losing money.

No4NJunk

Nope. The Lg4 has a flat tappet cam and an Lt1 cam (hyd roller) can't work in his application.

My LG4 was pretty slow, and one thing that made a noticeable difference was an open element air filter, and this can be done for pretty cheap. I dont know what a difference exhaust made, as I lost power when I added it as the car originally had an open y-pipe. I swapped the 305 out after driving it 2 months, but had a motor lying around ready for a swap. Some mods I can suggest, def go with the cam (comp cams XE256 maybe, Ive got a XE262 in my 350, pulls to 5500, whereas my LG4 305 would only pull hard to like 4000, then it felt like it ran out of steam), and exhaust as that y pipe and exhaust manifolds totally suck. I have them in my basement and cannot beleive they were serious when they put them on the car at the factory, its like they tried to detune it. Oh and the carburetor. Read on tuning the CCC, and get new rods and hangars. These made a difference, and were quite cheap. You can find these in jeg's. I use a B hangar and DR rods myself. Defintely made a noticeable SOTP difference on my 350. If you can find one cheap, perhaps an intake manifold, but I hear these make little difference over stock.

Given better air cleaner setup, cam, exhaust, perhaps gears if yours suck I see you having no problem with this integra. Of course, drop a 350 and you will be the king of this street racing club. I had the fastest car at high school when I dropped the 350 in my firebird, but then again maybe 2 people were faster than me when I had the LG4. I hope you take the acura down.

Oh, and I read your other post on the tech section about mileage, I get 13 around town and 17 on the highway with my 350, but I have a HEAVY foot. I got like 15/20 with the 305, but I also had a heavy foot then. Your car sounds like it desperatley needs a tune up with your mileage. A tune up may wake it up quite a bit depending on how much out of tune it is.

D Stroy H8

Definitley. Tune it up, a real tune up not a lube shop "tune up".
Race him in bone stock form with your car freshly serviced and tuned. Come back, tell us how badly you lost to him, and then by that we can better judge how much you'd need to mod to beat him.

Or if you want to mod first and try:

Open air element.
You have a carb right? Get a 1" spacer.

These are two extremely basic mods that should noticeably effect your vehicles throttle response off the line and throughout your revs. IF you got a little more cash ...

Aftermarket muffler. Try to get a warlock, so you can uncap it for races! That'd be an innovative/cheap way knock off loads of backpressure. Or just get a better muffler.

IMO these three mods are CHEAP for the gains they'll provide.

Hawk92z-TDZ

U didnt paste your sig there

My friend raced a RX7 with his 95 Formula and they were basical neck and neck the whole way down the street with the RX7 comming out a little ahead at the end. No idea on mods for the RX7 but my friend was quite upset, he thought it was gunna be an easy win. haha "he's very arogant"

Dingley I would suggest the XE250 cam 206 212 .432 .444 it will more suit your stock motor. Keep to a cam with a larger exh Dur to help with your restictive exhaust system, defenitly get some headers asap or if u cant aford them grab some TPI exh manifolds from from the reckers, they flow better then the stock ones and u might as well grab a TPI cat as it also out flows your stock cat and the rest of there exhaust from the reckers too, since ods are your 2.5" and the TPI's are 3". Not as good as headers and a high flow cat with the 3" but way better then u got.

does anyone else find it sad that a club started with a "play with your own cash" qualification lands an integra at the top of the chain? hehe spend a few hundred bucks and whoop his *** good.

dans82bird

man you can be running circles around this integra, wtf is that anyway...ahh who cares... its sounds slow

Port your stock heads - free + cost of tools
exhaust - 200?
headers - 120
cam - 100
aftermarket manifold - 150
open element - 30


so for around 600 bucks you'll be running circles around 'em

fast86z28

U sure about that? myt car unfortunately housed an lg4 between its fenders before i put the 350 in and the stock exhaust was a 2.25, i really dont think that the tpi cars had 3" from the factory, i thinks its 2.5 otherwise there wouldnt be such a big aftermarket for 3" catbacks, every1 would just go to a junkyard and grab one of a stock car

HOMESTAR RUNNER YEAH!!!!!!!!! love the avatar

rx7speed

oops here is my sig

Hawk92z-TDZ

It is a shad under 3" not sure exact specs, gunna look it up, just dont got time at this moment. All of my LG4's had 2.5" on them stock[have own'd 10 F-Body's now], but maybe yours was different, I have never seen the 2.25" on a V8 before but thats NOT saying they didnt do it. The cats on the Dual cat set up are 2.25" I think. Look up the book"Camaro Performance HandBook" by David Shelby, says right in there to replace the LG4 exhaust with the TPI's from a scrap yard for a better flow if u cant aford after market.

D Stroy H8

Great book. I ate it up in a matter of minutes!

fast86z28

damn if thats true hell im gonna go lookin for a tpi cat back, i have edelbrock tes headers and y pipe and a flowmaster muffler, but still got that stock i pipe lol

Matt86t/a

Yea dingley, definitely get a free flowing exhaust, like some nice headers, y-pipe, and cat back. Also, do not get a huge cam with a stock engine. Take it from me, it will destroy your low end, but your top end will be great. If highway racing is for you, go like me with 2.73s and a big cam. To take the Integra, you have to get out of the 16's, and with a stock 86 t/a, that is where you are.

School sponsored??? I hope not

no, not school sponsered..... haah.... yea right.... this is more of like a clique of people who do it, but its pretty well known...

rx7speed

wouldn't big cam and 2.73's kinda work against each other being the 2.73 would keep you out of the powerband a little more then maybe a setup of 3.23 -3.73

D Stroy H8

Highways are nice and all, but isn't this about the 1320? Get some a 3.42 posi gear off of another fbody. That way you'll launch way better and still maintain a decent gas mileage if you are concerned with the highway. If you aren't concerned with the highway, get some 3.73's!

Matt86t/a

The 2.73s only hurt you off the line. Once you are already doing 60 mph and you punch it, the cam takes over, and your topend is better than with higher gears. True, 3.23 or 3.42 gears would be much better in both low and medium end, and that is why they are in my list of things to do Definately get bigger gears Dingley, I was just saying that if you were going to race on the highway, to keep up with his 4 cyl topend, don't go too steep in the back.
