Default twin turbo 5.3.?

doin a 5.3 swap into a bmw, we planned on using 2- 40mm garrets. was wondering if anyone had any input as to how well these would do. we are going for INSTANT spool. Its not a track car, a street car. 5.3 is gonna be BONE STOCK. flipped manifolds, ls1 or ls6 intake, and front mount. planning on 12psi.


THANKS

EDIT: THE TURBOS ARE OFF OF A 1990 300ZX. HOW DO U THINK THESE WILL DO ON THE 5.3?

I have a set of T04b's mounted out back and the 5.3L I had in my truck before spooled them almost seemlessly when ya got on it! I pushed the ringlands on #3 cylinder at 20 psi and had a blast doin it! It was bone stock except for upgraded injectors! I would say your setup would work great!

a zo6 cam swap, good set of vlave springs, and a single 76mm turbo will get you your goal and then some.

I think 15 psi would be safe. Just check the tune and make sure it's spot on and you have good gas
