View Full Version : Oil Metering Pump
Magic8 08-27-2003, 07:51 PM For those interested in the oil metering pump, this the message I got from the company that makes the pumps, PCV Technologies.
"Thanks for your inquiry.
I would very much like to make an adapter for the RX8 engine, however, I need to find access to a car or an engine which I have not had at this time. As soon as I have the necessary information, I will start working on it."
Here is the link to the distributor website:

I guess the current design will not work in new Renesis.

This will allow you to add an external oil source so you use a 2-cycle oil instead of sucking engine oil.
Hi,
yes I have, and it is in stock. The price is $ 94.00, including shipping in the US.

dgrx8 06-27-2006, 05:05 PM i'm reviving this one!!!!!!!!
anybody done something like this... seems like a great idea rather than lugging around a trunk full of 2-cycle oil for all our fillups!
^I just came across this thread because of the bump...anyway, I am very interested in doing this, but wasn't postive if you can do this with our OMP.
Who is the guy in the second reply saying he has them in stock?
This would be sooooo sweet if we can figure a way to do this!
Razz1 06-27-2006, 11:22 PM Just have Racing Beat upgrade your pump!

AFAIK, the RB OMP mod does not have a seperate oil reservoir, which would be very nice.

I never attempted the mod but I tracked him down via this web site: http://rotaryaviation.com/oil_injector_pump_adaptors.htm
If you take this on, please plan on doing a DIY.

Yeah but then what happens when you run out of oil and toast your motor.
Now here is another question, whats wrong with the engine sucking motor oil? I use reg ol 5W30 on my RX8 but even RP or Mobil 1 are cheaper/qt than a Decent 2 stroke oil :scratchhe
I emailed them with a few questions so... I'm just waiting to hear back.
I'll definately do a writeup on the install if I can get a hold of one. :yesnod:
dgrx8 06-29-2006, 07:14 AM awesome!
it sounds like a great DIY...
w/ all the talk about using premix in all the other threads... i'm surprised this thread hasn't blown up!
swoope 06-29-2006, 08:34 AM replacing the pump will not change anything unless you change the map that controls the pump.
beers :beer:
I just got Richard Sohn's email this morning with some pics, this looks nice! I put the check in the mail and will impatiently await the OMP adapter :ylsuper:
It's the one on the left.

Cool, good luck with the mod. Here's a couple of related links you might want to check out:

demob05 06-29-2006, 06:25 PM For going through with the entire Mod for this separate set up, how much of a benefit is gained, as opposed to the Standard-stock engine motor oil (5W20 stuff) feeding the MOP??
yiksing 06-30-2006, 10:22 PM A lot can be gained, the synthetic oil debate will end and you can use oil for longer extended period instead of changing oil every 3000 miles. Secondly the engine idles and runs smoother and no more black exhaust tips. Engine life would surely increase.

Some bold claims there just from switching the oil injection method. I'm not looking to start a flame-fest but what are you basing that on? I've got lots of experience with two stroke motorcycles and oil/oil pumps on them. Which is pretty much the same concept as the RX-8 injection pump.
The exhaust tips being black is a classic symptom of a rich running engine (fuel/air ratio). Why would simply changing from engine oil to a two stroke oil in the injector change the fuel mapping of the car?
One of the main reasons I see doing this mod is to end the excessive carbon build up from injecting regular oil.
By seperating the system you can use synthetic oils without the waste of injecting it and prevent running into cooling problems, since oil does help tremendously in this department, running low on oil does not help in any shape or form. Doing this eliminates this problem.
Using a premix is far better in my eyes, I don't see why anyone wouldn't want to do this mod. It seems all good to me. :dunno:
:rock: I just got the oil metering pump adapter a few days ago and installed it, seemed pretty straight forward. Well, anybody interested in doing this......follow the link:

The way I see it, rotary engines requires an engine oil change in a shorter interval because you don't wanna inject dirty engine oil to lubricate the seals. Even if synthetic engine oil was used, it would have accumulated quite a bit of crap after a couple of thousand miles, by completely separating what gets injected into the combustion chambers (now a fresh dose of 2 stroke oil) an extended period of oil change is no longer as harmful. You can call these BS coz I have nothing to back it up but I believe what RG had told me about these or I might have misinterpret what he meant.
As for a smoother idle, it was apparent to me when I tried the premix myself but it might be just placebo effect. The lesser black exhaust could simply be cleaner combustion from the engine due to the 2 stroke oil but it might have been me cleaning the car way too frequently that time.

rotarygod 07-14-2006, 10:49 AM I have done this to my RX-7's and love it. I had a 2nd generation RX-7 that came with this adapter block when I got it. Great piece. I did the homemade conversion to my 1st generation RX-7 that is described on the 7forum and had nothing but problems with leaking. It was a pain in the butt.
As someone has already pointed out, you have less of a chance to get carbon deposits from oil in the combustion chamber as opposed to injecting motor oil. My main concern though is with the amount of crap that is in the oil. As it gets older and has more and more contaminants in it, they also go into the oil metering system. I don't like this idea.
It's not much of an issue to keep a separate reservoir filled full of 2 stroke oil. If it's large enough, just fill it when you get your oil changed. What happens if you run out? You didn't take care of your car!
SGPguy 07-14-2006, 05:28 PM I kinda like the looks I get at the gas station when premixing the 7, haha.

I read somewhere of someone who was able to creatively use a wave runner oil reservoir that included a low level warning light that was easy to adapt.
