What all would be needed to convert a miata to run an electric oil pump? I know its been discussed before I just cant find the thread that the discussion was in.

Search for an oil pump thread by patsmx5.

In short, it's not needed. So don't do it. Stock oil pump works fine. Anyone that tells you otherwise is full of **** don't listen to them. And I mean that.

Check out FM's track dog build, they used an Accusump system to help keep oil circulating through the engine during high g cornering. This was in addition to the stock oil pump however.

But what level will the factory oil pump hold up to? I was under the impression that after 250 the oil pump life was decreased by far. Also I figured Id let you know that I have a short nose miata and was just trying to find a way around switching cranks and running long nose oil pump with the stronger oil pump gears. Can the stock oil pumps handle that kind of power?

well by the time u end up with a pump etc it will be well over the cost of some billet oil pump gears. I believe they make em for the short nose cranks aswell.

Who makes the stronger shortnose OP gears?

I'd like to see an Electric Oil Pump up to the job. I searched in the past when I was racing and could not find anything.

Marc, these guys have done a fair bit of work using electric oil pumps in their race bikes: Electric Oil Feed and Scavenge Pumps

Long story short: they mostly rely upon them for turbo scavenge use, as MC turbos tend to wind up near or below the oil line pretty regularly. They've experimented with them as feed pumps, and their very largest one only made 40PSI, and that was into a tiny little motorcycle engine.

I don't see the benefit here. All else being equal, I have to assume that in addition to being more expensive than a well-built crank driven pump, the electric pump is ultimately going to be less reliable in the long run.

Seriously- how many of us have ever had an electric motor fail in their cars. Headlight motor, starter motor, wiper motor, window motor, fuel pump, etc. Show of hands. (counting.) Yep, that's pretty much everybody. Now, who here has had an oil pump fail? One, two... three maybe?

That is a valid point!

I've never had an electric motor fail! Or an oil pump though...

Seriously though, swap in a long nose crank and a set of billet oil pump gears if you're that worried.

It's not that I'm worried about it. It was just starting to look like I could get the crank for cheaper than I could find the oil pump. Cheapest one I could find at first was 260. Just ordered one from corksport yesterday for 187. Oh yeah I don't know if I'm breaking any rules by saying this here but if anybody needs a set of the billet op gears and an big nose op pm me I'm prolly gonna end up selling them.
