    M50 Oil Pump Questions

    Alright, well I am not sure if this is where I should post this question, but this is for those who have tracked their engine swapped e30's. I know most people use a E34 525 oil pump and pan, and I am wondering if anyone has any issues with running that set up on a track.

    I have heard of people running into oil starvation issues with the s50/52 swaps with this set up, but I have never heard it from people with actual experience.

    S54's have a semi dry sump oiling system and I also read that this was to solve oil starvation issues on previous generation M50 motors.

    So my question now is I am in the process of doing this swap and I have a M50 pump with a E34 525i pan, what can I do to make sure I do not run into any issues? Does someone make a nice windage tray for these? Mine does have an OEM windage tray built in, is that going to be good enough to stop the oil from sloshing around too much?

    I am also planning to rev the car to 8500, and this pump came off of a motor that obviously does not rev that high, will that be an issue? I know VAC sells and upgrade kit, and that will solve the oil gear from coming off, but does anyone make a higher flowing pump or one more suitable for higher RPMS?

    What are you guys doing to help this out in your actual cars you track? I do not want to go drysump either, please keep that in mind.

    Any help, or experienced advice would be great, Thanks!

    Are you installing an S54?

    I would get VAC's oil pump shaft at the very least.

      Yes, I am planning on doing the VAC kit at least, but honestly, I don't see many more options. I have seen windage trays with trap doors and stuff for other cars, and I also see they have a oil pan baffle. I am not sure if it has worked on the e34 525 pan though. That may be another option as well.
