As I understand, 8/8.5:1 compression may be boost friendlier but it will effect my low-end torque more. I think our more technical members could better explain why than myself. I want more power and higher-end torque without sacrificing a lot of my low-end torque. OT, Shaun, and a couple of STI (one EVO) guys seem to agree that dropping to 9:1 is a good medium for our engines. It will only decrease the stock 230bhp by ~4% (or ~9bhp) and I probably will not notice since the block will be bored, have head work, etc to improve flow.

Water injection, no intercooler.

Thanks, I have been trying to plan this out carefully so I don't get slapped with too many surprises. The most difficult was deciding what I wanted to ultimately accomplish and then look at how I should go about it. Watching cost has also been important as it sure builds up and it's easy to get carried away - I try to reality-check myself periodically. I will post my costs as they arise to better help others plan their own build. I think what eats my budget the most is the hydra. While conveniently awesome, its a good portion of my projected $6k cost (not including another $2k+ for the turbo setup). I wanted to try and setup my own engine management system but with projects/work, finishing my masters, etc it's like: "what free time? oh you mean sleep!"
I am considering meth injection but am holding off that decision until I am actually in the process of the turbo. Will you also be installing a tank that includes a level sensor, or installing a water pressure gauge?

Yup, I don't plan on ever making this a track/race car just use as daily driver. My goal is to hit maybe 300whp if I make a little +/-, I don't mind.
