305 TBI

Hi everyone, I have a 89' 305 TBI RS camaro and i was wondering what you all think about that engine. I have had a lot of issues with it in my 10 years of owning it. What would you do, sway to carburetor or what. Right now the engine isnt getting the gas necessary to run and am confused. I love the car but damn its a pain in the butt.

Have you put a fuel pump on it?

TBI was great for me. With a crane compucam 2030, 1.6 roller rockers, k&n, 3.42 rear end it beat 350tpi with a shift kit. You can fit 265s on the back. Holley makes an upgraded tbi intake and throttle body if you wanted to go that far. Mine had an issue with the accel coil burning up the wire that runs to the cap.

Or add tpi. Depend on your budget. PM if you have any q's.

The 3.42 gears will give you the most butt dyno improvement. I wouldnt go more than that. Youll shift pretty often with those gears and the 5 speed. The 265 tires will get you hard launches.

The car was a rocket off the line but fell flat after 4k. I dont think the stock heads or throttle body were flowing enough to pull hard on the top end. I still had the stock manifolds also. It all depends what your budget is. Parts are cheap for those motors.

Its alot easier to gain performance in those cars due to the lower curb weight. I had an L98 sitting in the garage so i was trying to blow the 305 and i couldnt. Did redline burnouts all the time . Ended up selling the L98 with a T5 for 1200 and built another 305. Still miss that car.

iv put my 305 through a lot of abuse and at over 170000 miles she still runs like new. every once in a while itll have a lil rough time but other than that she is amazing. with the right gears, full exhaust cam and tune they are totally different. oh and i kno u can fit at least 295's cuz thats what im running on mine. the tune is the most important part on these cars. check out thirdgen.org amazing website
