Looks like you have some fabrication to do or find a good fabricator who knows about rotarys.

What are the specs on that turbo? What kind of footprint? I used to have a 6.5 TD. The turbo looked tiny. If I were you I would take it to someone that can weld you up a manifold. That would be the easiest and best IMO.

Ah, I see that you are upgrading your GM truck to a 12A. Good for you!

Let us know how it turns out.

No way.
Diesel turbos have COMPLETELY different flow characteristics than gasoline engines.The turbine and compressor are tuned for low exhaust velocity and high CFM compressor output.A turbo is not just a turbo.Even the outside dimensions cant tell you what the CFM or spool characteristics will be.
Try a Hitachi T-18 or a TO4B with a .80 A/R

.......if you dont know this already,your not ready.........

maybe if his compression was 20:1 aaahahahahhaahhahahahaha, yea bro; listen to steve on this one. don't waste your money on building a manifold for that turbo. save the money and get the T-18 fc turbo, i'm running it on my 12a and it's awesome. pleeenty of power and it spools up instantly. buuut,


if you keep this thing, you are on your own. gonna need a completely custom manifold.

We'll see....
It wouldnt be impossible that it is all hooked up and physically running.
He'd be DAMN lucky if it actually responded correctly and flowed right for a rotary.Shear coincidence and luck if thats the case........
Me thinks not.
