The '85-'92 pumps all have the same displacement. They are infact the same pump except for the pickup feed and exterior changes.

Are you sure about this? There was a discussion about this back on the yahoo list, and if I recall correctly it was determined that the mk2 & na mk3 pumps were high pressure/low volume and the mk3 turbo pumps were high volume/low pressure. I'm not positive on this, just asking.
If you're right I definitely may go that route and just get an '85 pump and pan. Might end up being more expensive than modifying the 7M pickup I have though.

One of the members (cant remember who) said his dad is a machinist and they pulled both apart and measured everything and they were identical internally.

Cool, now all I have to do is find an '85 pump and pickup. Will the '85 setup work with earlier oil pans or is the '85 pan special?

Thanks,

Well, I got my new oil pump in the mail yesterday. It's an application for 82-88 5mge. It looks exactly like the one I used to compare to the 7mgte unit (and found they were basically identical). I checked the clearance with my 85 pan and it had ~5mm clearance. Looks good and I'm going to use it. pre 85, post 85, i don't know, but it works.

Where did you get this pump and how much was it? Did it come with the pick-up too? PN?

Thanks,

Christian,no worries as long as it's a good shaft,10 gte's with 5m pumps,gear/shaft not a problem.

So just to verify, a 7M shaft with a 5M pump will work? I'm putting my 7M back together so this is pretty important.
