either the STi short block, but I want the VVT heads, and in teh end it would be cheaper and easier to get a front clip for 6k with the new ecu, harness, and 6speed w/ new drive shaft rear diff, and the brembos + all the little goodies, still thinking building the block as a 2.2 stroker with JUN heads and an APS S50, but while Im aquiring parts Im sure something will change somewhere, Ryan do you have the HKS CF/Ti exhaust?? what DP do you have with it???
