and these

OBX Turbo Manifold Header Chevy Big Block Down & Forward with V-Band Flange | eBay

 

the TV8101's came standard with 1.39, 1.60 and 1.84 turbine sides. You can hybrid them with TV8102's and drop down into a 1.08-1.23 sizes. The TV 7* series go as small as .96 All TV series turbo's utilize a T6 flange.

The TV8101's move enough air to put down over 1000rwhp

 

so i must have a tv8102 housing currently because it is a 1.23, it did come with a 1.6 initially. I bought 2 new tv7 series turbos but they have 1.23 housings as well after the guy told me they had .95 housings but it was a good price so i cant complain

 

Many TV series turbo's have .95 cast into the compressor housing even though many different wheels are used. From the exhaust side if you had a 1.6 it almost has to be a TV8* series turbo unless it was swapped at some point. 81, 82, 83 . They are the ones that utilized the larger Turbines. In some configurations several were used on the same piece of large equipment. Think earthmovers.

 

Yeah I figured that much out after explaining in great detail where to look etc to the guy. No biggie

Do you happen to know where i could find parts for these turbos?

 

Detroit Diesel and big truck repair stores that service them. Many turbo companies rebuild them as well. Some will do stockers while others will mix/match to get the turbine and compressor combo you are looking for.

 

Well lil update i swapped my 8101 with a 7101 and found some .96 exh housings

truck spools much better now

 

 

and working on the new engine for it...

 

Have you had a chance to make a dyno or 1/4 pass with the current engine combo as a baseline?

Keep up the good work.
