Where can I order a OMP adapter?

I want to use the adapter that goes on the oil metering pump which blocks the oil supply from the crankcase and is fed from a seperate reservoir. Anyone know where I can order this?

This guy was super cool to deal with and it is a must have in my opinion. Super great fantastic idea. I dont personally know if there are any adverse effects from running premix through your fuel system. But i like the idea of the metering pump. So making it fed with 2 stroke oil is a great idea as far as i'm concerned. Also from what i understand, the reason that mazda's research said not to use synthetic oils in rotarys is because of the oil metering pump. So this takes care of 2 problems. I guess synthetic doesnt burn as well as natural oil in the combustion chamber. Enjoy!

I was always curious if anyone made these. So does the adapter sandwich between the the OMP and the motor? Do the injector lines need to be longer too?

I spoke with Tracy Crook from Rotary Aviation 3 months ago. He explained to me that the oil metering system that he designed is not intended for use on cars because of the sudden variation in rpm of a car motor vs a plane engine. He suggested to run the premix instead. He could of easily taken my money and sold me b/c I was ready to buy. He is a good person and is very smart. Pre-mix or leave the original mazda system.

Keep in mind that this will NOT work with stock twin turbos. It hits the oil return line for the primary. There is no way to make it work without butchering the OMP.

Doesn't make much sense, why don't they have that on the website or ask you when you buy if that is so? It doesn't change the amount being injected, it only changes the type of oil injected.

Ya, it goes between the omp and the motor. My injector lines were long enough, I do however have ss lines.

Garfinkle has posted about this before. If I remember correctly, it involves clocking the pump a different direction and making new holes.

Easier than it sounds and not for the faint of heart. Let's put it this way: I'm a hands-on kind of person. If I want to do it, I learn how and then do it myself. I tried it, saw what was involved and sold my OMP adapter.

I'm not comfortable doing all of that to the electromechanical device that supplies lubrication to the combustion chamber of my engine. I had that housing off that you're supposed to rotate, realized that the screw pattern was not symmetric and said "screw this".

Not to mention I couldn't tell whether or not clocking that housing would have any effect on operation. I wasn't about to pull it apart to find out either.

I currently run 128:1 supplemental TCW3 in my tank. I've had great results doing the same in my FC.

Agreed---the amount of oil injected isn't being changed. Perhaps Tracy Crook was talking about the "adjuster" that they sell. I bought the adjuster along with the adaptor because the OMP would not fit with my Aspec manifold. All the adjuster does is replace the OMP servo motor and deliver a constant injection volume regardless of RPM.

I can't see any reason why the adaptor itself can't be used for our cars.

I have had the thing on my car 2001 and it is still running ,as far as the reclocking goes,I have done several ,it is not that hard to do if I worked it out ,duh

You've got a new slogan. "So easy a Garfinkle can do it."

If you wouldn't mind, do you have pics of what exactly you did?

Yeah um, wtf are you talking about. Why are people always doing things like this. I have absolutely no idea in the world how this device would not work properly due to "variation in rpm of a car motor. It just blocks off oil supply from the front cover and instead replaces it with a barb fitting that would go to an oil reservoir. WHAT ARE YOU TALKING ABOUT! I'm starting to feel like a logical rational outcast on this forum!

If you think there is a potential problem with some part or idea ask what people think. Dont state it as fact that it is not going to work!!!!! Use your brain.

with love,

hsitko is right.

This part has NO moving parts. All it does is physically redirect where the OMP draws oil from. It is metal with a hole.

If this part was not designed for varying rpm use, then the coolant veins, oil lines, and water hoses weren't either.

Please people, DON'T propagate incorrect information.

And as long as you clock the housing to there everything lines up internally, then it will not change the operation at all. Kin of like rotating the outer housing of an electric motor, won' change anything except the outer housing position.

For those that are curious, attached is a picture of the adapter (right) and the adjuster (left). Like hitsiko and monkman stated, it only redirects where the oil is being pulled from---the barbed fitting (from your new oil source) leads to the hole in the center which in turn leads to the OMP. The original oil passage from the front cover is just blocked off. The keyed shaft to the left of the hole allows the OMP to keep the connection through this adapter to the front cover---so there is indeed a moving part in this adapter, but it has no effect on the metering of the oil that is being injected. I suppose that one could argue that the shaft/bushing/seal for this part of the adapter isn't designed to stand up to varying RPM's, but I've never heard of one failing and as Garfinkle pointed out he's had no trouble with his in over 7 years.

The adjuster, pictured on the left is a different story. This replaces the stepper motor completely, and simply uses a bolt with a jam nut to set a constant flow rate---it's no longer metering based on the ECU. I am assuming this is where the confusion in the above posts is coming from.

If you're really interested in how the OMP works, DamonB has some really informative posts in this thread:

I just ordered the adapter. They accept paypal, (res12@fairpoint.net) and it's only $88 bucks to support a company that has put a ton of R&D into rotary support (even if it is for aircraft, it still keeps their blood flowing)

I will see what happens when I clock the housing on the OMP (IF i have to with BNRs)

Does anyone have experience with this one?

http://jhbperformance.com/products.php

It comes with the adapter, and an oil line and reservoir. AND it's almost half the price of the other one.
