I think I'm going to log back pressure just to see and let you guys know. Hopefully it won't be bad

Isn't this turbo the replacement for the 71HPQ? I would think that it would be a quick spooling turbo on a stroker TA motor. Plus I have heard of some TSM guys that have run 8's with 68 series turbo so it appears to be quite capable on the right combo.

I decided to go with the bigger exhaust housing 96 and the new v band in and out exhaust side.

I'm kind of curious why you would use a 3 bolt on a motor like that. Are you class racing? The reason I ask is, I have a TA aluminum stroker motor and I would never use a 3 bolt on it. I want to move as much air through it as possible.

The outlet is 3 1/2 inlet I will go out and measure it I know it was bigger than the opening on the header I had a gap around the V band that I welded on to the header

Can you take a side by side with both housings centered to see if the flange extends further down?
I would my friend but I already sold the 3 bolt housing this is the closest picture of comparison I'm going out to my shop to measure the inlet like you asked I will report back

What size is the v-band on the inlet and outlet?
Inlet and outlet. And a side shot of my dirty ass exhaust headers can't wait to get all this stuff TIG welded and then powder coated but I have to wait till the TA engines in so I can mock up my wastegate pipe off of the header just waiting waiting waiting for the engine
