To start off I'm already in the process of purchasing a GReddy tuner turbokit , BOV, evo3 catback exhaust, map sensors, EcuTek when the time comes, and of course gauges.

The only questions I really have are:

Clutch
What is the limit to the stock clutch? I'm going to be making around 290-300 whp without changing pump/injectors (later project) what's a good clutch that I should look into? I noticed that clutches are rated for torque not whp though. So I thought the torque would be about the same numbers.

Fuel injectors/pump
. Has anyone had to do anything about this yet? GReddy and AVO said they did their testing on stock pump/injectors and was still making +93 whp (GReddy) +50-70 whp (AVO) with just turbo and exhaust added. Should I think about updating them aswell?

And this isn't really a question, but I've done a lot of research on the compression and I'm looking for personal opinions on this. For smaller turbos high compression is good for less turbo lag and more power through out, but 12.5:1 is ridiculously high nonetheless. Anyone got some good input on that?
