Well i've seen the miles thread, but i haven't seen a thread for specs and all that good stuff, i'm bored!
88 Formula 305 TBI *135k miles*
Flowmaster 80-Series Cat-Back. *Cat Delete*
Hypertech 160 Stat / Fan Switch.
Edelbrock Open-Element w/ K&N Filter.
Brand new paint job, all rust removed, new fiberglass wrap around replacement wing added, and Ram Air II hood. Bright Red along with some 16" Torque Thrust II's.
Throwing some headers on it soon, probably Hookers, lol it already sounds like a beast just from removing the cat.. huge difference.
It acutally burns the tires impressively from a stop, even with a non-posi 2.73 rear end, some of my friends tbi's cant do that haha, i hope to get a posi rear end soon with some 3.73's, maybe an engine swap in the future lol.
Just read my sig, it tell you basically everything.

I have a powertrax locker I need to put in. I put polly urethane engine and transmission mouts in, working on getting the rest done for the suspension.
Has shorty headers, 2'' y pipes to 3'' high flow cat and a flowmaster muffler.
Still working on it.
Buying back my ol' 89 RS from a friend, on wednesday.
Its going to be my project for this year. My goal is to reach 13s by spring, and maybe 12s by the end of this year, with the 305. And believe me, It will happen

Yes, I know its "Just a 305." "Why bother?" Because im curious as to what i can get out of the 305. This will be a fun experience. Im not buying all of this stuff brand new either. I am on a budget. If i want to go low 11's or faster this year, I will hop on my sportbike. I will document my gains as far as ET and MPH with each mod that i have done. I will also try to get the car weighed to document that as well. another thing I will do is list how much i paid for each part or list if i already had it sitting here.

i have a 92 Camaro RS with a stock 305 tbi with 288,000 mile on it (still has original engine and trans) the onley mods are a flowmaster exhaust and a k&n air filter othere than that the hole cars stock for now
but i eventually want to swap the 305 out to a 350 or 383 i dont plan to modify the 305 cause well it a 305 with 288,000 miles so im just going to save for a better engine. and i want to get a posi rear end for it. i also plan on get it repainted and get some of the chrome iroc rims for it

The best ET I've gotten in it was 10.00s @ 67.84mph in the 1/8th. I've gotten up to 67.99mph but I believe that was in 10.04 seconds. So yeah, it's slow. But it is slowly getting faster. I've got some 416 heads that need port work, a ZZ4 cam, an edelbrock Performer manifold w/TBI adapter, and a BBC throttle body waiting for it, but I have neither time nor money to put that stuff in yet. I'll be getting an EBL Flash to go with it so that is another $400 or so right there. Not to mention this car has gone to the way way back burner right now since I have big block ford project going for my wife's Mercury Montego.

Next year's projects....

3) 3.73 posi rear
4) Replace bushings as needed
After that, just cruise it and enjoy it for years to come I bought this car to drive, not to race. I have the Z when I want to run 13s. After the rest of this stuff is done, I'll probably have $13k+ tied up in this car, and it'll be nearly mint. After the car is done, then I'll be off to find my holy grail...a G92 M5/305 or 350 IROC
88 RS LO3 TBI
only mod so far is a set of chrome valve covers and fel-pro gaskets...
planned mods-
remove AIR system

aluminum heads
haven't decided on the cam
flowmaster headers w/ y-pipe
flowmaster catback (cat will be deleted)
etc
I.E. until i swap the LO3 out for a 350, haven't decided on an LT1, LT4, LS1-2-6 or if i get a bug up my arse, id love an LS7!
lol
