What kind of turbo is this? i saw it in a ebay ad at a good price so i'm wondering if its a .42/.48 or something elsE?

 

Mercedes turbo .42/.48, 4 bolt exhaust flange, internal wastegate, not adjustable...

Me and julio, installed one of these on a DOHC ZC, with an HF mani.. it spooled up good at 8-9psi.

If you buy it ... i got a spare 4 bolt downpipe flange for it.

 

so is it a 50trim or a 60? thanks a lot for the help. i might need that flange later on down the road.
