i made over 400awhp on just 92 with 22psi on a 35R,90degree heat.and stock bottom end,stock intake mani,head,clutch etc etc...

i dont see why you cant make that with a 37R...oh and your gonna need bigger injectors

 

My daily driver has a simple set-up: Stage 1 IX + 2.3 and i trully am happier then i ever was with a large turbo.... i think you would be wise change your goals (( unless your a drag racer))- the fact of the matter is: adding a larger turbo lowers your throttle response and simple is not a fair trade off..

 

I hear if the meth/alchy messes up wave goodbuy to your engine. that just what i heard tho correct me if im wrong. and honestly i have no clue what meth/alcy does or how it works havent even looked into it. i just heard that if it messes up than your engine is gone so i stay away. If you feel like it explaing what it does go right ahead.

 

I made 422 whp on pump with a GT35 @ 22 psi and I make over 500 whp on 91 + Meth daily driving. So far 6000 miles @ over 500 whp and no problems except my stock clutch went out :P.
