i am looking for shots from you guys with turbo 12a's of your hosing setup. aka... oil feed, return, and coolant feed and return. PALEEEZE

You can kinda see how I ran my oil lines in this pic. As for coolant lines...what are those? I don't run coolant in mine and there's never been a problem with it.

Oil feed comes from the oil pressure sender. Return is tapped into the front cover.

 

coldy; did you pull the front cover off and take it somewhere? i am probably just going to tap the oil pan for now. also, did you use the racing beat oil block thing? if not is it possible to snap a shot of how you tee'd off your oil sending area? ROCK!

that front cover looks like it has a pretty phatty oil leak going on there,

 

what is the thread size on the turbo for the oil in/out?

 

Nope, didn't take the cover off. Drilled and tapped while still attached to the engine. Then drained the oil and poured about 4 gallons of diesel through the oil system to clear out the shavings.

As for the feed, well, I didn't T off it. My pressure gauge never worked right, so I just took the sender out and screwed this in. I'm pretty sure the fitting is 1/8" NPT.


HormBM: Yeah, there was a very small leak out the front cover gasket. But I didn't bother to fix it because I was going to build a different motor soon anyway. And now that new engine is in it and it will be running again in a couple days

 

rock on coldy! thanks! one last thing though. where on the front cover did you drill?

 

feed is 1/8" npt thread, -4 stainless braided

drain is 3/4" heater hose and fitting

 

On mine there was a nice indentation to the left and down from the OMP. Just drill and tap right in the middle of it. If you have the other style front cover with just the flat spot I think you just gotta guess.

 

the most common place on the front cover is on a GSL-SE front cover. Below the metering oil pump there is an indentation that is the perfect size for a turbo oil return.

My bet is mazda used that spot for a turbo oil return on the 12aTurbo in japan.

 

WOOHOOOO! so i take it you used a 3/4" fitting for the piece tapped in the front cover?

 

coldy. i got the 1/8" npt to -4an fittings, but.. on the turbo there are no threads. how did you get yours in??? EDIT::::::


ok, i need a flange or something dont i? god i'm a fuggin idiot. where can i get this?
