Just to get 300 HP, you won't have too hard of a time. Your 88 350 iroc is TPI (tune port) not TBI like other guy said.





Long tube hedman headers, aftermarket Y pipe, single 3'; pipe to high flow cat, then a good cat back exhaust system.





Aftermarket computer chip





Port your throttle body or buy an aftermarket one





Port your intake runners or buy aftermarket ones





Aftermarket intake base





Larger fuel injectors





K%26amp;N air filter and a cold air setup





Aftermasrket cam with around 210/220 @.050'; and a 112 or 114 LSA..





That should be a good true 350 HP comboWhat Do i need to buy for a 1988 I roc Z to get more Horses? =]?
Hedders and exhaust would be a good start. Next you could get some 1.6 roller rockers. Might get you close to 300hp.





If it were me, i'd have the heads ported or get new aftermarket heads.you can up the compression ratio with lower cc heads. a cam with 1.6 rockers, hedders and full exhaust would put it in the 350+hp range
If you have to smog or emissions testing in your area it will be tough but doable. It also will cost more to keep it smog legal.





First thing is to help it breath better. New headers and exhaust system first, aftermarket intake manifold (reuse your TBI), underdrive pulley system, cold air intake, and just a good tune up. It will get you probably around 260-270 horsepower without major work done. You are limited by the cam and TBI injector sizes mainly. The computer will only work with what it can do, an aftermarket TBI Holley ProJection system will alllow you to tune and adjust engine power as you make changes. The number one thing that will help you after all this is done, is to install aluminum heads. It will unlock you past the 320hp mark for sure.
