My future evo 1 is standard. I want some grunt from it and a simple power gain so zorst and de-cat is first on the list. What do you guys think is best 2.5" or 3"? I want best sound and best power. Will I need to mod anything else if I fit a full turbo back system? Fueling mod? Induction kit? I don't want to go crazy with it as they have 250BHP as standard. It has a bov, leads, toga uprated fuel pump and race bearings getting fitted with an evo 8 crank as it suffered "crank walk" also lowerd 10mm with gab shocks and front and rear strut breaces, boost guage, turbo timer with rev counter. Just needs the zorst :-) I hear that with petes full 2.5" system and ram air kit that it will bring it up to 300BHP without doing anything else.
What do you guys recon 2.5" or 3"? Does 300BHp sound right for just a zorst and induction kit? Any other precautions I should look into first?
Cheers in advance
