Need some help putting a garrett housing on an HX40.

[Kevin TSI]

Hey everyone, I have a 6 blade HX40 which I am going to use for my current project. I am looking to make over 600hp and bought a .70 t3 BEP housing. Unfortunately, the angle of the flange on my top mount is set up for a garrett turbine housing which is a different angle than the BEP. I was thinking about trying to shoehorn the HX40 into a gt35r turbine housing. I have searched forever but have found nothing. Does anyone know how close they are to eachother.

Also, does anyone know the bolt pattern for a gt35 turbing housing, the diameter of the area where the wheel goes, the diameter of the wheel, and the diameter of the mating flange where the CHRA bolts into the turbine housing?

The garrett housing i'd like to use is the T3 with the 4 bolt 3" outlet since that is what our downpipe is flanged for already.

I do have access to a lathe. Also for the hp level I am shooting for, would a .82 or .63 A/r Be better for the HX-40?

It's been done, but you'd be better off with FPs version of the casting that's designed for non-BB CHRAs (the one they used for the original 3575). It's got a thicker area where the CHRA attaches which will give a more correct offset for the wheel to align with the scroll. I'd still try to make the .70 housing work though.
