First things first not bad mouthing ETS as I have almost exclusive built my car around their products. With that being said I’m installing a 6262 turbo kit and was getting the turbo oil drain flange ready. I noticed the mating plates do not match, I’m worried about oil collecting around the lip this will cause and eventually start to bake and leak. Is there any better option out there for this? I have attached some pictures to help with the visual.

 

The only options I know of are:

you can port that flange and give it some taper

or

you can use this. That fitting would require a complete custom drain and I can tell you from testing on my car it made no difference in how the turbo drained.

The flange that Precision themselves use has a round hole on it as well though.

Someone else might have another idea on this. These are just the things I found when I looked for my personal car.

It works fine. No reason to spend a bunch of time trying to use different parts.

If that's a ball bearing turbo put a .035" restrictor in the oil feed line.

 

Thank you for the responses, this puts me at ease.

 

I've always port matched the return flange to the gasket to help with oil draining. Precision ball bearing turbos have built in oil restrictors.

 

Nice work
