With a new filter the car calls for 3 1/2. Now when the car is circulating the oil there won't ever be that much in the pan, but better safe than sorry.
I would keep the turbo the way it is. Sometimes it's easier to make a good drain slope by coming out a little ways and then back to the pan. Bambooseven did this and had a super drain line.
I use gasoline because it's cheaper than filling it with oil just to check the line, and when you drill into your pan, the gasoline works really good for taking all the old oil and metal shavings out, so the gas should be in there at one time anyway. It really cleans good just by sloshing it around the pan and pouring it out. Repeat several times.

Make shure you do this in the garage near the water heater while smoking a cigaret.

Water will work just fine.Thats what I used.Just let the pan sit sideways for a while and then just wipe it down with a rag.

That angle looks fine.As long as it doesnt face towards the front of the car or towards the block it will be ok.

Oh yeah and water is cheaper than both oil and gas.Its usually free

Yeah, but the water mixed in with bits of the oil oil will be a nice mess. Gas cleans the whole thing, oil, metel shavings, it doesn't matter. :P


Save the water for your back, mojado!!!

not to jack but Ive got a few questions of my own, what do you guys mean by "clock" the turbo, I thought only the exhaust housing and compressor housing could be rotated... not the center section..?

So the idea is to have as steep of a slope as possible going into the oil pan right?

And to have the flange as low as possible in the oil pan, but above the oil lovel, for the best possible downward slope correct?

Another quickie for Stealth, Ive read a few threads on peope are getting to much oil to there turbo and its leaking into the charge pipes and ----. And they have to get one of your oil restrictors, what is the reason for this? To much oil pressure, what does a restrictor do (obviously restricts, but how?

And the stupidest question of the day, how do you feed the turbo oil? Turbo is high, oil pan is low, hows it work?

THANKS! (dont freak on the shitty questions, Ill be buying everything from you lol)

Well since your gonna buy my stuff. :P

Both of the housings on the turbo can be loosened and rotated on the center section, but because your turbine flange has to matte to the manifold flange, you can't really "clock" that housing, but you can change the rotation on the center section and compressor housing however you need to. So the turbine housing is "clockable", but it has to mount to your manifold, so it's going to be in the same place anyway.

So the idea is to have as steep of a slope as possible going into the oil pan right?

And to have the flange as low as possible in the oil pan, but above the oil lovel, for the best possible downward slope correct?
Yes. In order to see how you will make the perfect slope I like to attach all the lines, except the oil pan. Then you can see how the line is going to hang and get the best result after evaluating what you see.

The oil restrictor is a ball valve and you can adjust it from completely open (doing nothing) to fully closed. With a good turbo, you won't need one. The reason they sell so well is when you have

1) a turbo with bad seals

2) a shitty slope on your drain line
You more than likely will have a smoking problem. With

the restrictor valve people are basically cutting off some oil flow to the turbo which will

1) Not give your turbo enough oil to smoke, but enough for it to be lubricated

2) Give the shitty slope on your drain line a little more time to drain, hopefully giving you less smoke.

(and studies have shown that the more threads with the word "restrictor valve" also can lead someone into

3) Fear (that if they don't get one they are going to be fucked. lol <--and that one is the majority of sales.

The feedline for the turbo is pressurized by the motor through the line, that's why it can run uphill. The oil coming out of the turbo isn't pressurized, so gravity is the only thing that brings it from the turbo to the pan. That's why a good slope is needed.

oh... never thought about it being pressurized. And people just T the feed line from....? Im assuming somewhere on the block

Thanks for the info

The oil pressure sensor on the back of the block.
