My car has the following turbo:

Model: Mitsubishi TD04H-14C
Part. No.: 3517646
Serial Number: 216066

A long time ago, I placed an order from FCPGroton, for the oval gasket that goes where the oil return line mounts to the bottom of the turbo. The first time I ordered, the part number they indicated was 1378680, but the part that arrived was the wrong dimensions. About that time they posted an exploded parts diagram, and this diagram indicated that the correct part number was 3514546 (#15 from the diagram below)





Today I went to install this, and although the cutout oil port on this one is a different size (smaller), it appears that the bolt hole dimensions on this new part are identical, so I suspect it won't fit either.

The exploded parts drawing above, from the time of my second order (they don't have one now), shows that the turbo has a CBV diaphram housing that points directly to the front of the car, in the same orientation as the wastegate diaphram. This is a different model of turbo than the TD04H-14C I have, where the CBV points at a 45 degree angle off to the front right. I suspect that my turbo requires a different gasket.

Does anyone have information on what the correct gasket for the TD04H-14C is?

Thanks,
