Normally I'll search this out more, but i'm in a bit of a rush. Does anybody know what size AN fittings i'd need to make new oil cooler lines? Meaning the sizes for the rear iron, the front oil cover, and both ends on the cooler itself. Thanks in advance!

 

I'm pretty certain both the turbo oil return line and the oil cooler lines will use AN-8, but I think you will need to tap your own threads anyway. Rx7.com offers plug and play AN replacements I think, but they're hella expensive.

 

It's not that much more money, if any at all, to buy premade lines from mazdatrix. Once you buy the fittings, the hose, the right assembly oil, the proper tools. etc it adds up...real quick.

Plus the fitting you need for the oil cooler at a minimum on the return line is a goofy low profile elbow. It is supper expensive to source as a single part. It's basically a -10 hose end on one side and an 18mm on the other with a square 90deg elbow, in order to fit between the cooler and the frame rail.

That being said, if you insist on assembling it yourself. You need fittings that will adapt -10AN to 18mm at the oil cooler (both inlet on top and the outlet on the side) and the rear iron. (3 total) then you need a 16mm to -10AN for the front cover.

They are made in both steel and aluminum.

 

yeah just buy a set itll come out the same with out the work

 

Oil cooler and rear iron are M18 x 1.5
Front Cover is M16X1.5.
Recommend AN-10 hose size.

 

Thanks, this is exactly what i needed to know.

 

For the record, this is in the Archives.
