GroceryGetter83 would it have been possible to have the return feed a little higher?

I think any higher and it won't drain back from the turbo. Usually people drain to the pan, but I thought this would work.

It will work, you just need a 90° instead of a straight....

Ok, because I was thinking about going that exact route you took. But since I haven't done my front cover yet, where in the pan would the fitting be put?

Looking for one now!

Is that a weld on 90° or a screw in?

Weld on. I can't take credit though. I bought an ICT billet one. If one drain is good, two must be better, 😏....

Did you already tap that cover to pipe thread?

If you did you can get a -8 (or whatever size that is) to 3/8 NPT 90

OR, get a -8 to ORB (o ring boss) 90 which has straight cut threads and an o ring with a nut to adjust o ring squeeze. That allows you to put the fitting where ever you want and tighten the o ring. They are used in industrial hydraulics and are good to 2000+PSI so they are good here for return for sure.

The cover is tapped for 1/2" NPT. I will see if I can bend the 90* fitting I have to clear. I don't want to take the balancer off again if I don't have to. I will look into this fitting too. Thanks!
