Tapping into the sump ...

Im currently putting a turbo on my 4agte and wanted to know how some of you guys ran your return line into the sump?
Did you take the sump off and the put fitting on or did you do it on the car?
My engines in and I dont really want to have to take it out again I dont have that kind of time.
Let me know what you have experienced and what you think is the best way to run the return line
Cheers
Andrew

unless there is a port in the block that drains to the sump, then you gotta take it off and get a return line adaptor (alloy or steel) braised or welded onto the sump.
if you dont want to weld you could get threaded tube that you can wind nuts on both sides of the sump hole, but expect leaks and eventual loosening of the nuts.
either way, remove the sump - if you weld it in-situ expect to car to burn down to the wheels.
also, you want what ever is attached to the sump to be above the full oil level of the sump - if the drain from the turbo cannot breath or sees pressure, oil will be forced out of turbo bearings and seals (am not sure if this also applies to ball-bearing turbos).

i would do as above.
BUT>>>
it's possible that you could use a sump off a ae102/112 corolla, as long as you get the one with the oil cooler fittings attached... as far as orientation goes, it 'should' fit...don't quote me though.
it would look far more professional, but cost you a crap load...

Damn i was hoping there was some way to do it without taking the sump off. Oh well when I put the new head on I will do the sump as well.
Do I NEED to run an oil cooler if the car is turboed?

You don't really want to use the standard oil cooler return fitting as a drain for the turbo, as most turbos use a 1/2" or so I.D. return line. You really want to have a fitting to suite your turbo's oil drain.
As for an oil cooler, you don't have to run one, but it'd be a bloody good idea, especially considering your climate, if you live in Australia (except maybe Tasmania). It's pretty easy to get hold of a standard oil cooling system & fit it.

 you can use a hammer and punch to put a hole into the sump with-out any metal going inside. the sump will just open a hole up like when a bullet goes through metal.
then you can get the oil return pipe brazed onto the sump...

Just make sure you position it as high as you can on the sump wall (as thechuckster mentioned) or you will have dramas as I do with oil getting past the rear seal of the turbo. Mine is positioned only 20mm lower than the mounting lip at the top of the sump, and I still have issues unless the oil is 5mm lower than the "full" mark on the dipstick.

feral4mr2 - What you said is something that had crossed my mind. It sounds a bit bodgy but Im wondering if it will work doing it this way.
Also what kind of pipe should I use to make this return pipe?
Where would I get it from?

same with mine. 
krayzie, i got mine brazed onto my sump when i had it off after i drilled a hole.
but i have personaly seen it done with the hammer and punch on a gte that was in the car. seemed to work fine and still does.
i used some thin wall steel pipe that was the diametre i needed.

From a turbo-uneducated perspective, does the return have to go directly to the sump. Can you put a right-angled fitting in the oil filler cap or into the rocker covers ?

Sure you can stick a drain in the cam cover - but only if the turbo's mounted about a foot above the bonnet 
I really would suggest taking off the sump and torching in a fitting, I just used a common plumbing fitting on mine, then some blue ('aeroquip') hose back up to the turbo. Simple, cheap and it works! But taking the sump off REALLY is a good idea if you can manage it, you may not have to take the engine out of the car if you're REALLY crafty/agile

The oil coming out of a turbo is whipped up into a frothy milkshake after going through the turbo bearings which spin at 100,000 rpm or more, and it's non-pressurised to boot. This means the oil drain needs to have a direct downhill route to the sump, and the drain tube needs to be a large diameter. You certainly can't push it uphill into the cam covers!

Whatever you do, don't make the drain tube 7/8" - it's a total prick of a size.
You could drain the turbo oil to a collection pot (where it can "defroth") and then using a high temp electric oil pump, pump it up to the cam cover. You could use an oil level switch (from a 2JZGE) to trigger the oil pump.

i had brazed into my 2T sump a fitting for a auto trans cooler (from a radiator) - looked fine after bronzing on there.
my 4AGE uses the 100kw sump and, has the return for the factory oil cooler (which i don't use)

i did the one on my girl friends starlet while it was still on the car, just punched a hole in the sump and drilled it to size, then welded on the fitting,
then drained the oil and ran some cheap shit oil through a few times (just poured it in and drianed it didnt run the motor) pulled the oil filter apart and not a spec of shit in it
