Fd3S OMP oil metering pump question issue
 

My newly purchased fd3s is non op due to the engine need to be unflooded and a new oil metering pump, it has 90k miles and a single turbo uphrade, does the engine sound healthy to you guys??

welcome to the board. :)

either you left something out or you're the most cryptic person to post in a while. there is no way for anyone to answer your question about if the engine sounds healthy. fix the MOP issue, get a compression test if you're worried about the engine's health. if it checks out, then get a full tuneup and start from there.

Probably, excuse me for that lol. Thank you for the tip, i'll do that asap!

One person's version of how to change the OMP... https://www.rx7club.com/3rd-generati...my-how-675341/

If your car is a single turbo, it may be easier from above, but regardless it might give you an idea of the job. As mentioned late in that thread I recommend new OMP 'O' Ring and using new copper crush washers for the lines.

I am a little curious though....how do you know you need to change the OMP? If you have a single turbo, you SHOULD have a standalone ECU. And with an aftermarket ECU, you wouldn't get a CEL to alert you to a bad OMP. :scratch:

Thanks for your input! It's currently in limo mode and the guy i bought it from told me his rotary tech said to get it out of limp mode the OMP should be changed, it's running on stock ecu but he also including a new Apexi Power FC with Commander, should i just install the ecu right away?

^Although installing the PFC will take it out of limp, I agree with your tech and would still replace the OMP. You can probably source a good used OMP from the Parts For Sale section for < $50. Otherwise, you MUST pre-mix. Then, BEFORE driving your car, install the PFC and get it tuned. I can't imagine the stock ECU is adequate for ANY single turbo and driving the car that way puts you at great risk of running lean and blowing an engine.

As a new owner, I highly recommend getting a copy of the Factory Service Manual. Downloadable versions are available in the FAQ sticky in the 3rd Gen. section for free. I would also spend a few evenings reading through those same stickys. ALOT of information. The car is not your parent's Honda.
