hey i'm getting ready to turbo my can and need to know, is it okay if my oil inlet and drain are on a slight angle rather than straight up and down? if not what will happen? and i keep reading about these oil restricters like the stealthmode one, what does this do and do i need one?

 

Slight angle is fine.

 

oil restrictors are so the turbo wont see 100~psi oil pressure like the engine(makes it adjustable), if your turbo is worn and the seals suck they will leak at full pressure.

 

Up to 30 degrees from vertical.
