I have an evo VIII, I have a fuel pump, megan o2 housing, perrin 2.75 dp and 3 inch from that point on, injen intake, injen intercooler piping and 272 cams. I made around 320 whp on the mustang dyno. I am looking into upgrading my turbo, exhaust manifold and intake manifold (if I have to, would a ported a polished one be best?). Anyways I am looking for the BEST response possible, not really on peak hp but quick spool and sustained power. I am looking for a modest 450whp.

 

get full bolt on's with a fp green + E85 tune. It will be a street monster with very quick spool
