I was wondering about a few things, maybe you guys can help me out here.

oil drain : what is some of the easiest ways to do this?
from what i've read you have to drain the oil into an unpressurized location.

external wastegate downpipe : which would be better running the downpipe from the wastegate into the downpipe for the turbo or just having the wastegate dump into the atmosphere with say a 24 inch downpipe.

wastegate springs : I know what "bar" means but in relations to what does the w/g spring have to do with? so I want to boost 10 psi into the engine what spring would the w/g need?

 

1- Gravity Drain= if ur turbo sits high in the engine bay, just have a drain line go down to the upper oil pan, and there

2- Depends

3- 1Bar= 14.5psi, you're a smart dude, figure out the psi you want to run, convert into Bar, and there you go

 

do it like the S/C peeps...drain back plate....

 

Has anyone one done it that way? I'm planning to do mine soon, just trying to figure out the easier way.

 

dont jack my thread

 

I'm sorry, I forgot you own this website. 2 of the same questions in the same forum does make sense.

 

LOL I 2nd this motion. Just disregard it.

Just to reply to what you said, a drain back plate wouldnt seem logical on a turbo, as it would still need to be gravity fed (correct me if Im wrong). Not only that but mainly the fact that most people sit their turbos on the driver side, and thus u'd need to have -10AN line going from the turbo over there, across the back of the rad, then somehow route it bet'n the frame and the accessories into this plate. Makes for a pretty long hose when it can just be made ~10-14" long by draining into the upper oil pan at an angle.

On a S/C yes it would make sense, since its a straight down drop, but for a turbo thats on the other side of the engine bay its just a hassle

 

would it be cool if let's say an oil cooler is place after the turbo then the drain back plate?....or will it result in oil starvation...sorry if it is a stupid theory...
