Hi all this is my first post, i'll try not to bore you, i have a 91 Z28 5.7, got it about 6 years ago, sat at my brothers for about the last 3 years and finaly decided to have it restored, well the engine was taken down to the bare block and all redone, only thing we added is a 3" pipes from the manifold back.

questions?
1. what headers do you all think i should get for it and what is the extra HP i might see from them.
2. throttle body, are they worth buying and again what extra hp will be seen from the change.
3. does anyone know the price of a procharger off the top of there head? and with buying and installing a procharger, is there alot of other things needed to be changed and or added to run one?
4. anyother bolt on upgrades for added HP?

not looking to change the cam and all that right at this time or any other big *** engine stuff to add hp.

thanks all for any info

Aaron

 

Well with the TB upgrade you will want the plenum and runners ported to match. We have a twin 58mm TB on ours with the ported plenum and SLP runners and the thing runs like a beast.
