3.2 turbo height
I have turbocharged my 3.2 and am having turbo drain trouble. I am draining into drain plug hole and it wont drain enough even at idle. There is a definite slope from bottom of turbo to drain plug but if i remove line from turbo it starts to drain sump at that height which tells me it is below oil level in engine. My question is how high compared to say the rear engine mount are you guys running your turbo to utilize gravity drain. thanks

Stock 930 (low) location here and I have no oil drain issues.

What size oil feed are you using? You might be over-supplying the turbo? Typically, -4AN is used for larger turbo's (T4's etc) and -3AN for the smaller ones (like T3's and GT28's etc).

you are draining into the sump/drain plug?? If it is not keeping up you have way to big of feed or way to small of a drain.. I use 3/4 inch ID drain for my car

Im using a 3/4 id drain line and a -4 supply, maybe i'll go to a -3 and try that. I'll also swap turbos but im confident theres nothing wrong with the one thats on it. thanks
