Building the motor is the costly part. It is possible, definitely. Justanothermp5 has a lot of experience with where youcan spend your money to reach your goal. It's not going to be easy. All I can say is build a motor and go from there. Do it right the first time and have the peace of mind. These motors can easily go boom 10psi+. It's the weak internal that make the motor unreliable (rods and pistons). Even with my setup I don't think I'll hit 300whp. XD
The main piece to the build that will give you big numbers are to:
Upgrade to fmic for better air flow
Bigger turbo ( need to build motor, unless you plan to run under 10 psi)
Upgrade to 505 intake manifold (quoted a 34whp gain)
Ssafc or anything better ( can add 30whp)
Upgrade to 440cc for higher boost
Wideband for tunning purposes.
Exhaust system preferrably 3" ( down pipe, and mid-pipe till the end)
Others can add to the list or subtract. That's my experience at the moment. Of course there's other small things I'm missing, but it's a general list.
