Practically same turbo as in my setup, except my turbo uses the 5-bolt ford style turbine housing.
Not to hijack the thread, but I have a few questions.
Ben, Just out of curiosity. How was the backpressure in the turbine with a .63 A/R? I've always wondered why AMS went with such a small housing on thier 37R kit. So far, I haven't noticed much of a drop off in power all the way up to 7300 RPM.
I was a bit curious as to what your findings were. I suspect going with a .82 housing would definitely benefit this turbo. Unless you've found the P-trim wheel in a .63 housing to be sufficient up to the compressor's limits. How high were you guys revving to during testing?
