shit man, just do a 14b... were you planning onusing a straight Garrett style T25 or the 2G DSM T25 w/ the Mitsubishi turbine housing that has the round inlet?

if you were gona use the DSM T25 then you can easily bolt on a 14b in its place... the 14b's are damn good turbos and have taken DSM's to 12.0's and are breaking 11's as we speak... so you can DEFINILY use one w/o regret on your car.

if you already have a T2x sized turbine flange on your turbo manifold, you have to stick w/ a T2x turbine cuz the T3 is a bit bigger although its still the same shape.

a 14b will definitly let you reach your goals, be super efficient. its good all the way up to 1.0bar on pump gas, 20 psi if you have race gas. in fact, w/ just 7 psi, you could ALMOST hotpipe it...
