Okay, you don't make much sense is your motor in there right now a REAL* 7m-GTE because if it is, then you should have a oil return, if not you can return it to the oil pan, you'll have to create it though.

Another thing is you need a turbo wiring hanress, it sounds like you don't even have that?

You need a turbo engine harness (same year as the 86.5...an '87-'88 should work though), assuming you are going to use the turbo electronics. You can't use a NA harness due to differences like the AFM.

This diagram shows the oil feed/return line:

The following pages from the link above show how to remove the turbo (and it's connections). The oil return attaches to the block just aft of the oil filter...the feed attaches to the block just aft of the oil pressure sensor (Page TC-11...bottom pic).

Thread moved to the 7M-GE Tech Section...that's the place for swap info like this.

Sounds to me like the poster doesn't know the differences between a 7M-GE and a 7M-GTE... and it sounds like he's trying yo drop everything right on top of the GE.

Yes, the user really is not confirming anything for us to help him on. This is hard because we can only guess what he has, and I can tell you, I am not about to do that, so until ( Better ) information is available for this, I am not suggesting anything.
