Supporting Mods

Hello, i have looked back a little ways and may have missed something and im sorry if i did but i would like some help on a GTP. What supporting mods does it take to run a 3.4 pulley? And how much power can this total setup make? Or any information on a 3.5 pulley? Thank you for your help.

I believe I read somewhere that each .1 inch decrease in pulley size adds about an extra pound of boost. Can't tell you what supporting mods are needed though, I haven't walked down that road yet...

For a 3.4 inch pulley, you'll need colder heat range plugs, a reprogrammed pcm, and a u-bend delete minimum.

A high-flow cat would be highly adviseable also. It would be strongly advised to keep an eye on KR (knock retard) with a laptop and a monitoring program to prevent piston damage.

Don't even think about being cheap and buying less than 91 octane fuel.
