wow thats a lot of steps  |
Based on all the reading I do at work all day
if/when I get an STi the mod path will be:
Step 1: Turboback + custom dyno tune
Step 2: Fuel Pump + injectors + turbo + custom dyno tune
I believe that the STi topmount intercooler is as good as any out there. I would only replace it if I was going to go to a frontmount intercooler. Higher lag but more power potential and no more heatsoak worries. Also, I believe that upgrading fuel rails is overrated, but then again I only have 8 hours a day to do research
Powerwise I don't think it is worth going beyond those 2 steps unles you are going for an all out built block == $$
Honestly a custom suspension setup will make more difference on the track.
