I don't think high drive pressure is going to be a problem with the size exhuast housing I'm running. A HX35 wont spool well with the huge exhaust housing. I had thought about a HE351 or the VGT option, but the T3T/4 is working well and pushing a couple pounds of boost into it will help it make a good 35psi. The T3/T4 I have is only rated to push 20lbs of boost efficiently. I'm already at that boost level. Yes the HE351 would do everything I want, but the compound turbo setup will look and sound cool. Its more for the wow factor. This is just a fun time car for me. I enjoy messing with the local diesel truck guys...
