I can get a real good deal on this turbo and im wondering if a t4/t3 turbo with a .48 a/r turbine work on a maxima? Im just looking at boosting at around 5-6psi. Im afraid that the turbine may be to small and I may never see boost (turbine size may be to restrictive). thanks

 

No, that turbine shouldn't be too small for that amount of boost. Think of it this way: a KA24DE is capable of taking that turbine to 15 PSI of boost. And that's just an inline-4. Just curious, what trim of compressor is it?

BTW, what year Max do you have?

 

im not too sure of the trim, is their away to figure it out by measuring the diam
of the wheel?

 

Honestly, I'm still fairly new to the world of turbos, so I couldn't tell you how to figure out just by looking at it. I'm guessing that yours is probably like 50 or 57-trim though. A 50-trim would be good for spoolup, but I think a 57 is better for peak boost. (Anyone feel free to correct me if I'm wrong here)
