if you are staying all motor the GSR trans isnt what you want, youll want the B16 Tranny much shorter gears.

WHat are you spending $2000 on? jesus.

If you have a b20 already, then my advice is

1) Buy a USED GSR head for like $400 (i know where one is)

2) Buy a Rage/Hytech header from me $350 (best header out right now proven 10whp gains)

3) Buy a GE LSVTEC kit so you can put your head on

4) Buy and ECU or chip your existing one (pm me i can do it)

5) Buy a Skunk2 Intake Manifold

6) TUNE TUNE TUNE

that setup should make around 175whp/120-125 TQ. Its about $2000 if you do the head swap yourself.
