Sorry Dark for posting in advanced, wasnt really sure where that would go, but my question is a little more in depth than that. What I am really trying to get it, whats is going to be faster/more reliable in the long run. I planned on getting the rebuild (approx $2000.00, and the Stage II Hahn (approx $3200.00). Is that going to be any better than doing the whole 4G63 swap? I read the thread in "things we've seen before", and I know it will be a PITA, but I dont care. My friends all have VR-4's, a GSX, and a frickin Taurus SHO. I want decimation, I want to destroy them - Just for around $5000.00 :) So whats going to be the best route, cause my current engine has 140k, definitely is gonna need a rebuild soon.

Dude, just rebuild your engine and put a freakin turbo on it. It's faster than a GST.

And it's not just a PITA, it's a fire hazard. This board knows of one dude who did it and it burnt his car down.
