Is this to small?

Are you boosting the engine with stock compression or lowering it and what type of tuning?
That turbo will work good for 8psi on stock compression.

I would like to lower the compression with a .120 mls maybe even a .140. What are the benifits of running stock compresion over the lower the compression. I'm using miller for the tuning. Do you think the s52 is too much for this snail? Could you fab up a down pipe for this turbo? The max on stock comp is 8psi before you need to get a thicker gasket right?

I'd be looking at a .86 or even a 1.06 AR Turbine housing for that turbo on a 3.2L

A split T4 1.06 would be my choice.

If your lowering the compression then you can run 15psi easily and that turbo would be way too small.
A GT35R would be an all around good turbo and put you in the 450whp easily.
What do plan on using the car for?

Daily driving, autox, every blue moon the drag strip. And Otis do you make down pipes? And what about the 6262 turbo?

I make down pipes for the 60-1 and GT35r.
I know on bf.c their suggesting the 6262 and will be good for highway pulls but a bit laggy around town, that's my opinion though.
