Turbo mounting questions

[FST4RD]

Hi all, had a thought about mounting a turbo... but thought it's worth checking out.

Can you mount your turbo with the compressor housing facing straight up? This would mean that the exhaust would exit straight down, the pipe between the exit of the compressor housing and the intercooler could be perfectly straight (as long as you mounted the turbo and intercooler in the right place), The you would have a 90 degree bend between the filter and the intake.

Maybe there's a flaw in my logic somewhere though?

good luck getting oil to drain from the turbo it its at 90 degrees to the ground

[FST4RD]

Yeah that was my only thought about the whole thing...

I'm sure I've seen it done on a few Subies, so there must be a way around it?

make sure the drain is not sticking straight out for too far. Maybe even redrill it at an angle. Surely the oil pressure is enough to move it a little to get it flowing

but why?

Pretty sure Garrett recommend no more than 15degrees tilt otherwise oil restricts in the drain and they pop the oil seals

[jaypines]

maybe you can do that but you need a scavenge pump for the oil drain.

[FST4RD]

but why?

Well my thoughts behind this were that instead of your dump pipe doing a 90 degree down and then anouther 90 degree under the car, you could do away with one of them making a slightly less restrictive exhaust. Same goes with the intercooler piping, you could do away with the 90 degree straight off the turbo to the intercooler meaning less restriction all round.

Does this sound right? Or am I just smoking too much crack

Just because there is a bend doesn't mean there is a massive restriction

[FST4RD]

Fair enough... then it could be potentially cheaper, saving on a mandrel bend or 2 then
