Only on the interenet you can get away with showing descriptive pictures.
that adaptor Marty talks about looks like this http://carcraftinc.com/images/20259.jpg

hey marty and muffler mike...could u guys help me find info on the other holes(which marty suggest are for water...i do too)...to see if i could just plug them up...
also...on picture 4 u could get a good view of the way the turbo is arranged(where the exhaust and intakes and everything else go's)...i was just looking at it and it occured to me that i might not be able to use the turbo because of where the intake is in contrast to the exhaust hook-ups are. any feed back would be great...

ps i put a pic in of what kind of turbo it is in case you need to know(#5)...

COOL PICTURES HUH...(THOUSAND DOLLAR CAMERA BETTER TAKE GOOD PICTURES...LOL)

THAKS A LOT!!!!!!!!!!!

for running oil to my turbo, ive been told to take off the oil pressure switch, and run a fitting from that to the turbo. the run the oil return to the fuel pump block off plate. will this create good enough oil pressure. or would i be better off using a oil pump with the fitting to run out, and the pump plugged?

That is the way it is done on most cars. you do not need a lot of oil feed to the turbo, which is why you use such a small line. Just make sure that your discharge is large enough.

trey, i've always heard that turbo's require gravity drainback for the oil... so your idea would not work if the turbo was located underneath the rear apron, for instance.

Electric pump would work.

turbo will be put up top. im not too worried about the oil return. just wondering if id be better off plugging the oil pump and running it out of there.

The turbo needs a good supply of oil. It spins a hell of a lot faster than anything else in the engine bay.
The return must be either gravity or by pump. If the return isn't big enough (usually atleast twice the size of feed), the oil will back up into the turbo and blow the oil seals. There must be nothing in the line at all for it to get blocked with, the oil comming out of a turbo ressembles the froth you get on the head of a Beer more than oil!
I would make sure that you use an uprate oil pump for the turbo.
If you run the turbo's down low, the return must be lower or (like Porsche use) you must use an extra oil pump.

>>>Electric pump would work.<<<

that's been tried before by someone on this forum, and it didn't work because the pump was junk... it's just something else to break down.

but if you do happen to have a real-world source for a cost effective scavenge pump for turbo use, please share it with us.

Would a 3psi fuelpump from a mini be suitable?
or must it be an oil pump (what with fuel being much more viscous than oil)?

the problem i can forsee there is will that pump take the tepmerature?
Like dan said, the best way would be to use a real scavenge type pump. For that matter, maybe use a real dry sump pump with one stage of scavenging and then plumb the pump in like a wet set up and problem solved.

As for the top question, i pulled the plug on the top of the case right above where the oil pressure sensor goes, used 1/4 npt tap.
This is where i got my oil feed to the turbo. Same galley, 6 of one, half a dozen of the other. on the return, it was the standard turbo to fuel pump block off plate.
but my first version, i wanted to be slick and use braded hose. Well after the fittings, there was no room to flex what little hose was left. I then used two Long radius 90's and then looped the braded hose. (all in -8) It looked cool, but didnt work worth a sh_t. because of those two high dollar 90's, it would not drain fast enough. after a few minutes of running, i was noticing oil being pumped out the exhaust. I then went to a strait shot piece of radiator hose, 5/8 id, black, ugly with hose clamps, but worked great. so make sure it drains back freely. Unless you have a turbo that has the right seals to prevent this issue and can run under oil pressure. Im sure they make it but dont know what kind of seal this would be. All i know is a to4b will not take pressure.

Sorry, I do not have a source. I might look around though...

yeah, I had problems running a Mocal electric oil pump, specifically (allegedly) designed for the application of returning spent oil from a turbo. It worked for about a couple of weeks...
Mocal then suggested running a red Holley fuel pump, as they run this pump as a transmission cooling pump. I was extremely sceptical, but tried one out and it is still working to this day. I know it's not designed to pump hot oil - but it works. That's all I gotta say 'bout that (Forrest Gump)... matt

Hi
Apperently VDO do an electic oil pump, they may be more reliable.
