The T-5 should be able to handle the torque if you are not drag racing it all the time. As far as I know, the best T-5s are not really rated for that much torque, though. (If you make about 360-380 lb-ft). You can beef them up with aftermarket rebuild parts if you are worried, I think you can make it good up to 500 lb-ft, but then at that point you are spending as much as a TKO. Advantages are that the T-5 is still lighter and smaller.

The stock T-5s with a short shifter also shift nicer than a TKO with a short shifter. I don't know how the beefed up T-5s shift. Google G-Force.

What other tranny options do you have? Can you use a TKO-500?

I'm not familiar with your bellhousing options, but I am partial to the hydraulic throw-out bearings. I like the theory behind them, and I like how mine works, but setting them up is kind of a pain. It's definitely more work than a cable clutch, and will cost more.

Got any pics?
