I have a turbo garrett from 6-8L diesel Iveco truck.
cold side:
A/R 0.72
trim about 55
wheel diameter- 91 mm-67mm
in.-67
ex-55
Hot side:
A/R 1.34
trim about 90
wheel diameter 83mm-78mm
ex-80mm
what do you think about this, is it good for 350?
Thanks for any reply.

 

Im not claiming to be an expert, but from what Ive heard, that;s going to be way too huge on the exhaust side. The compressor side is big, but doable. I'd imagine if you can find a smaller a/r turbine housing for that it would work pretty decently.

 

I’m not sure that I’m following the numbers you’re listing, but if you mean that the minor diameter of the compressor wheel is 67mm, that could be worth a bit of power (most in that range are good for somewhere between 500-1000hp), but the 1.34 turbine A/R isn’t really the hot ticket for a street car, or even a short distance car. For a land speed car or something that spends longer periods at WOT or near it it could be a nice turbo.
