i have access to a freshly rebuilt t3 with cold side .60 and hot side .63 wastegated to 10 psi. would this be too big to use on stock d16y7? i'm currently installing td04 from 02 wrx with safc and 450's, but now thinking about possibly using the t3. when would the t3 start boosting and hit max boost? if this would work probably would save it for a later project since i would definately need to ditch my ac.

 

the .63 is a bit big, but in a goood way. Id say 2500> building boost, and 10psi by atleast 4500.
I'd take it over the WRX turbo.

 

im thinking of putting a turbo of that size on my B16 when i get it...

 

you will get some lag, but I would go with the T3

 

Sounds like a Tbird turbo, I use these all the time and I love them. The lag wont be that bad if you run a 2 1/2" downpipe and a free flowing exhaust. If the .63 A/R exhaust bothers you, you can always swap it for a .48 A/R unit. It will interchange with the SAAB 900 and 9000 units, or a Tbird unit that came off a automatic car, these are .48 A/R.This is almost as big as a T3/T4 unit.
