Updated! - Free Turbo Drain Line Kits (Qty 4, with strings attached!)
 

Okay Guys,

We had talked a while ago about oil line kits for the Miatas. We've put together the first version of the drain line kits. Since we don't have any Miatas here on which to develop these, we are turning to you guys for testing.

We have four prototype kits available for this test, two each of two different types.

Economy Kit -This kit has what we feel is the minimum hardware for a quality kit. The kit makes use of reusable AN fittings at the connection to the turbo, so that you'll not need to mess with worm gear clamps at that connection, easily removing the turbo when maintenance is needed. The connection at the pan uses a push lock fitting. The deposit for this kit is $35.90 plus shipping.

Regular Kit - This kit includes a second reusable connection at the pan, so that the drain line can be disconnected at the pan, as well as at the bottom of the turbo. The deposit for this kit is $38.90 plus shipping.

Both kits use the 1/2NPT threaded adapter to install into the aluminum pans on Miatas. The drill and tap are available separately as options to the kit. Keep in mind that the tap is $16.50 and the bit is $23 at McMaster, which is where we purchase these types of items.

So here is the deal... We need someone to install these, and let us know what they think of the kits. Whomever takes one of these prototype kits must be willing to complete the installation within a week or so of receiving the kits. We'll also need pictures of the installed kits.

To keep folks from taking a free kit and throwing it on the shelf for later, we're going to attach some strings to the deal...

Whomever wants to do this for us will need to pay for the kit before we ship them. Once they have installed the kit, and have supplied us with their thoughts and photos of the kit actually installed, we'll give them a full refund of what they paid, including shipping.

Each kit can be supplied with a drain flange for turbos with drain flange bolt spacing of 38, 44, and 50.8mm (center to center). The buyer must let us know which turbo drain size they need before we ship.

We are working on feed line kits, but are trying to source it all in -3, instead of -4.

Hit us with an email, at Sales@TunerToys.com if you want to help us out and get a free drain line kit in the process.

Thanks from Craig

Correct me if I'm wrong, but as long as the correct flange at the CHRA is used, and the hose is long enough, and the tap is the right pitch.. how could it not fit?

This is a great deal for somebody that is getting ready to do an install. Kotomile is correct in saying that this is a pretty simple piece to get right, but if TunerToys want to eat some money to get quality feedback, then somebody should jump on this since it will save you a bit of money.

the economy kit makes more sense than the regular. why tap the pan an install an AN fitting, to only screw an adapter onto that.

man... im building up my turbo stuff.... if it were only time for me to install it...

Stuff looks nice. I'll have to keep it in mind when install time comes.

Only reason I can see is that you only have to seal the fitting going into the oil pan once. If you ever needed to remove the drain line, you would be removing an AN fitting, that will not leak when reinstalled. It would prevent leaks and keep you from wearing out the threads on the pan.

and it's easier to upgrade to stainless braid later...

Instead of bothering with the -10AN to 5/8" connector at the turbo, why not just use a 5/8" standard hose fitting? Cut out one more piece from the puzzle.

Put me down for a regular kit. I have a lift and a dig cam, and I need to re-do my oil drain anyway.

I've regretted just about every time I've said that phrase. :)

When designing something that we are going to sell to customers, I have to know firsthand (or second in this case) that it fits witouth issue and will be a quality product for our customers. I'm a stickler for that.

Since we are using the push lock hose, the connection at the pan will have to be cut off, or the fitting un-threaded from the pan to remove the drain line from the engine. We could have eliminated the reusable fittings from both ends to get the cheapest possible solution, but then you'd be removing the flange from the turbo, just to disconnect the drain.

Because of that, we feel that having the re-usable fitting at the turbo is needed. Having the re-usable fittings at both ends is maybe a little bit "extra", but allows for upgrades and replacements with less headache.

Something I may have missed on, is the diameter of the hose itself. These kits use -8 hose, which is smaller than the 5/16" hose you guys have mentioned. -8 has been fine for many of our Honda 1.6 and 1.8 liter customers, so I expect it will work for the Miata guys as well. If you guys have a good argument against -8, we can revise the kits to use -10.

Craig, pity I already have the braided lines and I'm not sure if my tuner hasn't tapped the pan already this afternoon. When I left his shop he had not yet done so but the pan was completely out of the car. If it helps you at all I could try to email him.

Hey fellas, what is the center to center bolt spacing on my turbo flange? TDO4-15g greddy kit turbo. Is -8 big enough, or should I get -10? Thx

How much is just the turbo drain worth?
I use exactly what you have pictured in your economy setup. But my in pan fitting is a slip fit not permanent reusable slip in. Have to use a hose clamp.

About $44 is what we are thinking for the complete economy drain line, and $49 for the Regular style with the re-usable AN fitting at the pan.

Craig

Not enough of a price difference to merit having both kits. Just sell the Regular kit.

add a SS braided line option
:bigtu:

Would the AN fitting at the pan be better at 45 or 90 degrees?

That's actually what I was thinking too...

Good question. Those answering please keep in mind that the final solution must be A/C Firendly.

Craig

Phil, Mach, and Ben have agreed to test out the drain line kits for us. Thanks Guys!

We do need to know what the drain flange bolt spacing is for the GReddy Turbo. Does anyone know this, or have a turbo handy that they can measure? The bolt spacing from center to center should be 38, 44, or 50.8 Millimeters. Anyone?

Also, we have sourced all of the pieces in -3 for the feed line using the factory feed port. Once they arrive, we'll update this thread.

Thanks from Craig
