And a downpipe, bellmouth design.
Hopefully you've already though of all of this or you just added about $2k to your build
And maybe new pistons...the stock ones suck.
The main thing for me is getting the car back on the road, so I'll be keeping the shortblock stock - from what I've read so far about the 2010+ STi shortblocks its strong enough for what I want to do. As for the turbo I talked to Bryan and he says I can run the upgraded VF40 as a normal stock VF40 until I get supporting mods as you mentioned.
