turbo question

[blacksupra]

I have the stock ct26 turbo but I was thinking of getting a 60 trim or 57 trim which one is better? what else do i need if i go with any of those turbos?
One more question
Which one is faster stock 1jz 5 speed or 7mgte with 3' cat back, DDp, cai?

Depends on what you want - fast spool, better reliability, and lower potential power limits = 57 trim.

Slower spool (tho not by much), slightly shorter lifespan, and higher potential power = 60 trim.

As for which one is faster, that's anyone's guess. Try 'em both.
