Clutch options for turbo setup

I'm in the process of beginning my turbo project. My first step is to upgrade the clutch and throw in a lightened flywheel. My question is regarding people's feedback on which clutch to use. I decided to go w/ an ACT clutch but am trying to decide between two different clutches. The two clutches are:

Clutch Kit Number: NX9-HDSS
Torque Capacity: 241
Pressure Increase: 45% Over Stock
Price: ~$420

Clutch Kit Number: NX9-XTSS
Torque Capacity: 323
Pressure Increase: 95% Over Stock
Price: ~$480-500

The turbo setup I was thinking of is ~230hp

JWT ECU
HKS BOV
Walboro Fuel Pump
Cobra MAF
370cc injectors
T25 turbo
Bluebird DET Manifold
Custom Downpipe
Hotshot Intercooler
GReddy SP 2.5 exhaust
Some sort of manual boost controller

So....couple of questions, first of all, how much torque would this setup create? Secondly, both of these clutches are designed for street use but I want to know the difference in the engagement. Third, I plan on doing minor tweaking to the turbo but nothing extreme (staying under 300hp), for people who have used the 241 rated clutch, did it hold up to mods. to your turbo?

Finally, (last question) the cheapest I could find these clutches was from Options Auto for about $400, have you guys found anywhere cheaper? Thanks for your help.
