how do I make an Oil return line gasket from OEM pan?
 

I purchased a used turbo kit from a site member and the kit wont include an oil pan. The seller told me there is a way to custom drill my OEM pan and it would work. Here is what he said.

Seller-"No the oil pan is not part of the kit. I have the greddy pan but its on my car. You can use the stock pan. It will have to be drilled and taped for the oil feed lines for the turbo. If you buy a greddy pan it already has a place for a turbo line. I think i payed almost 400 for my greddy pan new"

Seller-"Your best bet will be to call a few places. They sell a kit just for this kind of thing but i cant recall what its called. If you have the extra money i would buy the greddy pan. If you don't get the greddy pan. Get your self a extra oem pan that you can tap. Just in case you make a error. And it will be easier that way. "

Unfortuneatly I dont have any extra money for a Greddy pan so I was looking to get some information about this procedure to DIY.
OR..
Does anybody happen to know what the premade kit is called so I can search for one on the net?

Thanks

oil pan return line
 

As a former owner of a twin turbo 3SI car, it can be done. What you can do is this:
1. drain and remove the oil pan.
2. go to Sears auto section or any store that sells tools. Get a tap to make the threads that will match the size of the fitting you will use for the oil return line, the line coming off the turbo. Summit Racing carries many sizes for stainless braided lines and the fittings for these. Get the lines that are rated for at least 220 F temps and are of the oil resistant liners.
3. drill the hole ABOVE the maximum oil level in the pan.
4. by hand, slowly turn the tap in one revolution, then back it out slowly...be sure to tap the threads at a 90 degree angle to the pan.
Lubricate the tap with oil to make it easier to turn.
5. install the threaded male fitting a half turn more after hand tight or bottom it out gently using a round gasket. Double check to be sure that the oil return line does not touch or comes no closer than within 2 inches of the exhaust.
6. Double check the Air fuel controller you are using is correctly calibrated.
7. Double check that the aftermarket wide band O2 sensor is calibrated correctly...as you know, rotary engines do not handle any knock as a piston engine can do for very brief moments.

Installing an oil pan return line is easy if you are patient.
If anyone else has alternative methods, I am sure they will chime in.

Not possible on our car.

Ack_ my mistake. I misread the earlier post on what he was looking for..gasket fitting vs simply how to do the return. It looks like your earlier post with Link shows the issues more clearly.
It seems these RX8's are a bear to modify.
I just picked up a new RX8 40 th. Anniversary with sport package for a song at the dealership and have been looking into a turbo setup, but the dealership gave me a Free, no deductible, lifetime warranty on the whole drive train so I am hesitant to mod the car.
It is getting 23.3 at 75 mph sustained driving for a three hour trip but it sure could use a bit more torque. Now I see why many want the turbo upgrade.

thank you for the link to information MazdaManiac.

NP.
Which turbo kit do you have?

MM being helpful without any sarcasm... what is the world coming to? I'm just so ashamed.

Well, it wasn't a stupid question! What am I supposed to do? :smoker:

I put my turbo drain straight into the existing drain . Not sure what Greddy supplies with a new kit because I did not have it .
I went to a place that makes hydraulic hoses and had them fabricate a fitting for me just for the job. Way less hassle than removing the pan .....
Means I have to pull the hose off every time i change the oil but it has not been an issue .

I bought the kit from Ti Carbon. Here is the link pictures of the kit that I bought.

I havnt received the kit yet, but would like to have all the necessary parts together ready for installation when I have the time. (Which will be a few months, having my vehicle shipped over to SKorea from stateside.)

It's a Greddy Kit that you have there.

Again, so you are left with two options:

- Drill and tap your stock oil pan.

- Buy a modified oil pan like the Greddy Oil Pan. I believe Race Roots had a high capacity oil pan as well.

I've had a few turbocharged cars including my Miata that originally did not come with a turbo. I had to do the drill the pan method on all of them because they didn't have aftermarket oil pans available. If you take your time, it's not that hard of a job. Just make sure that when you tap it, you're very careful. You don't want to mess up those threads - you only get one shot.

Just use the fitting that (should) come with the kit.

It's a drainplug that has a hose fitting on it, so you just loosen the hose clamp (no need to remove) then spin the plug out and move the hose aside to let the oil out.
Thread the plug back in and tighten the clamp back up.

Both eazy and peazy.

my drain plug was missing also, when i asked raceroots guy he said it was 100$ or so for the fitting to get a new one from greddy
