The Renesis uses a computer controled oil pump to pump the right amount of oil in to the combustion chamber. Is that depend on the rpm or on how much fuel and air is in the chamber? Do you guys think that a oil computer can be run without the rest of the intake components so say you could put a cararbutor on a renesis motor and have the oil pump controlled buy the computer and then have a cararbutor for the fuel. Cararbutors are so easy to tune. Because the motor doesn't care if it is fuel injected or cararbutored

Bad idea. I don't think the stock ECU would run at all.

I'm not entirely sure how the carbed rotary's ran the OMP...

They had a rod that ran from the throttle linkage on the carb to a laver on the metering pump. The wider you opened the throttle, the more oil it pumped. Pretty crude, really. But then, so are carburettors when compared to the infinite adjustability of an ECU and injection.

the reason I asked was because I know fuel injectors are great and all but carbs are much easy to work with than fuel injector and any one can work on a carb. not everyone have the knowledge to work on the stand alone systems that you would need to run the motor with fuel injectors and another question is will you be able to run the motor with out using the stock system on a renesis because they control the amount of oil put out by computer control. Is it a seperate unit or is it relient on the stock ecu. They didn't do side ports before because they could not control the oil control enough not to clog up the exhaust ports. that brings in to question if you will use a Renesis on older rx7 alltogether.

I think you'd be nutz to even attempt putting a carb onto a renesis.

I tried to say that in a nicer way Basically, it won't work, ever.

my friend, if you're serious about performance, and have enough cash to consider putting a big 'ol carb on there, and muckin' about with all the things you'd have to (ignition, fuel system all the way back to the tank, the entire multi-length intake system, etc) you're MUCH better off getting a fully programable ECU system like a Motec M4 or something... take it to the dyno, and that would be even better to tune than your carb... i believe that there is a piggy back system (or something) in the Motec units which are there to control a secondary pumping system (for water injection on drag cars or whatever) which you could use for the oil metering system... really, old tech = bad idea.
