Doesn't list actual wheel sizes..
To shift the amount of air it says..
It will do the job you want..
May pay to port the wastegate alittle bigger ??

I personally believe that will be way to small.

A rear A/R of .7 means it will spool up real quick but run out of puff up the top. same with the front a/r of .84, it will produce boost early but a limited amount and again not much up top. It would be perfect for a skyline as they are not after the kind of cfm our big 4ltr's are after, and are quite responsive revving engines, ours aren't (think torque not hp). I think you would lucky to see 5psi with that one, and possibly over spool it and bang... no more turbo.

You would be better off with a rear housing around a a/r of 1 or bigger (not too big), and around 0.6 on the front.

My 2c.
