In my layman's opinion:
#1 ditch the stillen kit, sell it and recoup some cash.
#2 Buy another stock motor, sell your fried blank canvas to someone going for big power to recoup some cash.
#3 Buy one of the following turbo kits:
BP Kit (Self install or far less expensive shop job)
Gamma V3 (More mechanically inclined self install or shop job)
FI or AAM (Even more mechanically inclined self install or shop job, Bigger hit to wallet for kit)
#4 Take the car (or even farm out the entire build) to a well known competent tuner that does Ecutek. JTRAN in houston is 4.5 hours away from you. Z1 in GA is only 6.5 hours away. If you can't get a base tune and drive it (or want to have them do the whole build), spend the $500-$1000 to have it transported there and then rent a car (or fly there) when its complete and drive it home knowing your tune is rock solid.
FYI I had JTRAN tune my car. Start to finish he did it in 4 hours and it feels like it came from the factory with 500+whp. He knows what he's doing.
I think these steps will get you to the most headache/hassle free 500-550whp. If you want more you can go E85 and/or build, but your wallet will need serious commitment and the stillen kit really stops making sense. Either way... ditch the stillen kit.
edit: Since your new motor is not going to be physically inside the car anyway, you can save a little on the install of an AAM or FI kit since they suggest pulling the motor for installation. BP and Gamma can be done without pulling the motor (with the BP kit being far easier to install).
