Well, if you are only going to run say 15 psi, then you will not need the open track kit.

The street kit will easily do that. And your block will handle 7-8 psi daily with that setup for a long time.

You would be suprised how much power you will gain on 8 psi over stock. I would say for 250whp you will have to run in the 14psi range for that turbo.

The setup I am working on getting money for right now is Pauter Rods, CP Pistons, Sleeves, headgasket, and ARP Studs.

Let me know if you have any questions, I have become pretty knowledgable about this stuff in the last couple of months, and you also may want to check out turbod16.com
