M35 New Turbo

It won't be a 76mm turbine.

If it is a 56mm or 60mm turbine with a 71mm compressor then it will be a GT3071 hybrid. So about 425 to 450hp.

GCG have machined a massive turbine into the back, (you could be right with 71mm) which is why I didn't go for one as the rear housing can't handle the flow that size wheel requires.

I dont think you could go much larger than 60mm compressor wheel either without breaking through the compressor housing. Mine is 56mm.

I would say that Craig's comp is 71mm or 76mm

That's what I wanted to hear Glenn, thanks for the impressions of the turbo

Can I ask why your mechanic decided to go with ~60mm tube for the suction pipe instead of staying with 76mm all the way through?

I rang the mechanic earlier today, and his thoughts were that going bigger than 60mm would make a very small difference if any. He said something about the pipe being the same size as the intakes on GTRs.

I also enquired about getting other pipes made up. He said a rough quote would be about $500 to make and fit. He's going to talk to someone later this week about getting a run of exact duplicates made from mine to see if a run of 10 would be possible if the demand is there. I'll let everyone know when I find out about that.

Don't the GTR's have two intake pipes that size?

Cam, if Craigs compressor is really that big and he's running the standard intake, that could be the source of his backfire problems...
