can someone help me find the part numbers for the pipes which connect to the oil and water turbo lines. I highlighted them in this picture.

Well, one is listed right in your picture.

1) Pipe, oil: 14-290: N370-14-290A or N370-14-290B

The other would be on the previous page of the parts fiche (pg. 1-C5 of the '89-'90 fiche)

2) Pipe, water in - turbocharger: 13-530A: N319-13-530A

The water outlet and oil inlet pipes are listed on the same page.

I'm actually looking for the pipes which connect to the parts I've circled. Not those exact parts..

And I gave you part numbers for two pipes. The oil drain pipe and the coolant feed pipe.

The coolant feed pipe just bolts onto the LIM, and the oil drain connects to another short metal pipe connected to the front cover. Is this additional metal pipe what you actually need?

The short pipe connected to the front cover is:

Pipe, Oil Outlet - Front Cover: N370-14-260A or N370-14-260B

Page 1-J7, and referenced on page 1-M3.

Thanks, that's the oil pipe I need.

As for the water pipe, I'm not after the water pipe which connects to the turbo, but the water pipe which connects to that pipe. In my picture I've circled white space next to that pipe to indicate that the part would be there if it was shown on that page.

Also, what's the difference between the parts which have B on the end instead of A?

As I said, there isn't one. The water feed pipe bolts directly onto the LIM. Water comes through the block where the freeze plug is missing on the rear housing.

The PN probably just changed at some point.

in the mazda part numbering system (which is similar to mercedes actually), the letter suffix on the end of the part number is for revisions.

so in theory if there is an update to a part, the letter will change to reflect this.

the problem with this is that the revision is not always to the part, it can be, but it could be a vendor change, it could have been a price change. occasionally the part changes and the part number does not too.

the dealership will receive the latest part number revision ONLY, unless there actually is a difference in the parts.

I can't be bothered with trying to remove the gaskets off the old parts that's why I'm chasing these pipes.
So for the coolant feed I'd have to get a new LIM?

What are you trying to do here?

My turbo was leaking oil so I bought a rebuilt one from someone off a forum, and when I installed it there was oil leaking from the oil drain and feed because I didn't replace the old gaskets.
So I'm going to purchase new gaskets and pipes to fix the problem, instead of just getting new gaskets and removing the old gaskets from the old pipes (i heard they're really hard to get off).
On an unrelated note, when I took my turbo off (the new one) there was a huge amount of burnt oil in the turbine side and I don't know if this is because of oil leaking into the exhaust intake of the turbo by seeping through past the turbo gasket that's connected to the manifold or if there's a problem with the oil seal inside the turbo. I used an old gasket for the turbo to manifold so maybe the seal wasn't perfect.
