Re:Which T3 for D16??
 

More info since I am leaning towards a T3 as well for my D16. I will probably spending a lot of money on a brand new turbo so I want to make sure I understand it as well as the guy who designed the turbo.

What will different trim wheels on the compressor/turbine do to performance? I am guessing bigger will produce more top end and lag? Are most T3 housings interchangeable? Like if I buy a .42/.48 T3 and decide I want more top end can I just change the housings to .60/.48 or .60/.63 or whatever? Is there a general rule on what specs to buy or do you just use trial and error and see what fits you best?

There's like 50 million different combonations of trim and A/R's you can get for a T3 though .42, .48, .60, .63, .70, 50 trim, 60 trim, 68 trim, 76 trim, different stage wheels blah blah blah.

I just ordered Maximum boost by Corky Bell also so I am hoping that book will clear a lot of my questions up.
