I just bought a 1997 Z28. it already has a chip, cool air intake, new flowmaster, and a shift kit in it. im looking for some ideas on what else to put into it to give it that extra boost.

thanks

 

bigger throttle /body injectors /headers

 

On the contrary, the throttle body and injecters you have in it will support over 400 hp easily. I agree with the headers statement, go with long tubes and a mandrel bend Y pipe with high flow cats, that'll get you something. You could think about putting a more aggressive cam into it if you are comfortable with engine work. With what you have on it right now, and the headers, you've almost maxed out bolt-ons. The only other bolt-ons I can think of would be a 160 deg. thermostat(that can get you a little bit if you get the PCM tuned correctly) and a new housing for your throttle body(that'll get you about 7rwhp or so).

 

tie your subframes together - that will stiffen up the chassis, imrove handling& launch as well as reduce hatch rattle for about $150. torque converter will make mad improvements also.

 

Thanks for the ideas guys

 

One thing about chips. The computer on your car does not accept chips, so I think the seller of the car gave you some embellishment there.

 

that i did not know that. thanks for the heads up

 

Thats why they sell hand-held programmers to "force" the ECU into working with the chip, hence why people sell Chips for LT1's and LS1 motors with the computer.
