I'm looking at one and it seems perfect for my power goals. But turbine wheel specs aren't listed, and it seems like a relatively uncommon turbo. All I can find is ".58a/r exhaust, .60a/r compressor, 45 trim, up to 350hp, great low end." Anybody know what the turbine specs are for this turbo? I'm running a DOHC ZC and I need to know if the turbine wheel will even flow enough for 300hp on a d-series. Thanks ladies.

 

No one? Someone out there has to have used one of these things.

 

the ebay "57 trim" turbos are .50 AR 44 trim compressor housings, with a .63 AR turbine housing.

it should be pretty close to what u are looking at.

 

nice, thanks for that tip. Anyone got any specs on the turbine wheel?

 

I did some more digging and found that the turbine wheel is a stage II 69 trim. What would you guys say are the limits of a stage II wheel with a .58a/r housing? I'm thinking that it seems like a good compromise between good spool and decent top end somewhere around 300whp. I don't plan on going any higher than that.
