Gt35 is way to big and wouldnt spool well imo. I dont know much on corvair engines tho, how much rpm they can turn. That sized turbo on late model 4 cyl cars make many hundreds of hp. But can be a touch laggy. A good 61-62 mm compressor wheel can make 800 hp on a small engine. That turbine size 62/67 mm or so is a size that would be better on a higher rpm higher base hp 4-6 cylinder imo. It be ok if you had a built engine that could handle 400-700 hp or so.

Thanks Orr89rocz

'how much rpm they can turn'

I would say 5500-6000 RPM.

Corvair engine would be what we can run and test turbos on right now.

What about the T3/T4 Hybrid Ebay $100 turbo on the stock 80hp Corvair engine?

Found out from watching a few 'Unboxing Ebay Turbos' Youtubes to ask sellers if it is a Max Speeding Rods turbo.

Have found a couple of the T3/T4 turbos and they have offered a little off and say two year warranty.

Cool.

Okay.Then that is the plan.

Be neat to put all the gauges on it and see what is going on.

Litlle Corvair engine on a test stand and T3/T4 turbo.

Good thing about test stands and Corvairs is they are air cooled.No muss no fuss!
