I have no idea how much HP you will make... however, I would add some transmission upgrades to that list, unless you want to have a VERY SHORT quarter-mile. The stock STI tranny is certainly capable, but 530+ HP (which you need to do 400+ HP at the wheels) is going to tear it out of the bottom of the car.

I've driven a 500HP STI tuned by Dyno-Comp here in AZ, and it had a parts list a mile long, which included upgraded engine and tranny mounts, clutch plates, front and rear differentials, entire suspension replacement and more... not to mention a nice set of brakes to stop it! :-)

 

U should do good....alot of it will depend on the the tuning.
U have a setup that not many people have tried, it will be nice to see what it does.
380-400 on a dynojet should be no sweat...
380-400 on a DD dyno a little harder...but if my car did 371hp on a DD dyno with a green and stock motor...i don't see any reason u shouldn't.
