hey guys i got a 305 tbi on a 92 rs. all thats done now is a flowmaster exhaust and a high-flow cat. i was planning on putting a lot into the car engine wise. so how much horse do u think ill gain from the 200 i have now with these mods: edelbrock headers, edelbrock tbi intake, matching edelbrock heads and cam,new chip, spark plug wires, cap and rotor, shift kit, electric fan, new tbi throttle body, and a 75 shot dry nitrous system. thanks

 

Need specs on the heads & cam.

With a stock 305 TBI with just an exhaust you'll be lucky to put down 175rwhp.

 

im sure u dont need the exact specs to give an approximate estimate. i was just wondering, very roughly.

 

Heads vary radically, and like I said before, don't waste your money on that intake. It's crap. You need something with more flow. If you get a new throttle body, you'll want to get a 2" bore, dual injector, since they really aren't that much more than the stock 1 11/16" piece, and flow ALOT more. Get yourself a dual plane 4bbl carb intake from the same series as you were gonna get the TBI intake from, and get an adaptor plate with a 2" bore. The stock bore size on the intake bone you in the long run, it's the biggest thing stopping your L03 from making good power.
