More specifically I need to know what thread pitch I need on the 12mm to -4AN adapter...is it 12x1.25 or 12x1.5?

1.25 sounds bout right iirc also..... are we talking about the adaptor to the block for the feed or the adaptor on the turbo for the feed?

I'm guessing it's for the feedline off the block...judging by the listing 935 has for the kit.

Yeah just found a part number for a 12x1.25 to 6AN adapter...then I'll just use a reducer to 4AN.


Also, is the 935 site correct for oil drain fittings? 1/2NPT to 5/8 Hose adapter?

Or do you have to drill/tap the oil pan for the 935 kit? It's what I'm basing my oil line setup off of.


I'm looking to order these tomorrow:

12x1.25 to 6AN adapter
6AN to 4AN reducer
24in of 4AN oil line
1/2NPT to 5/8 hose adapter
24" of oil compatible high-temp silicone hose

Anything else I'll need?


I've never seen what the OEM oil return setup looks like on the 7m...so I'm trying to get everything together BEFORE I take it all apart. :p

It's 12mmx1.25mm to -4 adapter. Those are harder to find, so many people will run a more available 12mmx1.25mm to -6, then -6 to -4. It works just as well, just more hardware.

If you want me to send you any pieces, let me know. I have them all now.

How does your kit hook up to the OEM oil drain on the engine? I haven't seen what it looks like so I can't even take a guess... :(

Get in touch with Jon (MDC), he supplies them. I'm getting a set from him.

We use the same flange everyone else does. It has a stock type flange for the block, welded to a -10AN male to accept the drain line.

Same as MDC and others.
