I second the .85 housing, he could have a .58 on it now. The turbo housing can be used for tuning aids also. My TE69 was totally out of control from a dig on the street until I put a .85 on it. It already had the front mount. I had a .58 and then bought a used .63 housing had 2 stripped bolt holes in it and I had to use the .85. I didn't know if it was going to fit but it turned out to be the match to calm it down. Didn't mess with my torque converter. By the way what is your turbine housing A/R?
