Looking for one to swap around and modify for my jetta. Just need to be in rebuildable condition.
I know where some are Tom if you don't find one.
What years are you looking for? Do you think one of those monsters can fit into a Jetta?
All Merc T3's were the same. It fit in my Wife's 86 Golf, it will fit in a Jetta.

I did have to persuade the brake line on the passenger side, that's with an ATP manifold.
Oh, and the Merc T3 cold side is the same AR as the Volvo T3, the Merc turbo I picked up had a wanged compressor wheel, I swapped the Volvo cold side over and it was fine. (my machine shop guy just happened to have a tired Volvo T3 laying around)

I'm not sure on the years i know some had a funny valve on the compressor housing i'd rather not have that. I have read that they are a 50 trim compressor. I have been doing some math and it should move the air i want to move. I may get a .36 turbonetics turbine housing and run an atp manifold and an external gate. But probably gonna see how she acts with the stock hot side and a merc cold. Might also try the merc hot side but that too would requre a different mani or an adapter.
Found a merc comp housing and a 50 trim wheel seperate on ebay.
