Very interesting. Thanks for posting this info! I'm still curious though to see how your modified RevUp pump performs compared to the Cosworth and Nismo pumps.

I'm not knocking, what you've done is fabulous and I give you props for laying the ground work.
Another issue is that the mounting points for the HR pump don't quite match up on the DE motor. One of the holes is slightly off.

You are welcome. If I had both to test against, I would definitely show the differences. This pump takes the upgraded pump most 03-05 DE guys do, and build up on it from there. The Nismo pump quite a bit of loot and I'm comfortable saying most of us are not going to need more than 8500rpms. My original goal was to spin to 10k with my setup, but after looking at the build and what I was doing, 8500-9000rpms is fine. The Cosworth pump and our pump is basically in many ways the same in what we are trying to accomplish. I'd like to get a Cosworth in my hands so I could see just how much different our two upgraded pumps look side by side.

For builds looking for an oil pump that will perform at higher levels and not break your bank, this is easily the way to go.

Is the cosworth pump a modified stock one or is it new cast housings and new gears?

I think it's a modified stock one. There was a thread on another site talking about the pump a while back. I'll see what I can find on it and post it here.

REVUP oil pump and basically the same thing we do to our pump. Of course there are few things here and there we may do different, since I don't know their actual process.

Cosworth pump is just a revup pump with low friction coating applied... waste of money. This is a reasonable price, but still I'd like to see chromoly gears be offered by someone. I don't see how it could cost $1,000 per gear... but then again I haven't called to ask pricing.

Funny you should mention that. I am actually working on billet gears now for the revup pumps. As soon as I have more data to pass along, I will let you guys know.

New pump is here, so now I can start pulling it a part to draw the gears and see what is possible with billet gears. This option will most likely put pricing between the cosworth/my own and the nismo pump. I hoping to come under the amount of the nismo pump, but it all depends on the amount of people interested in a billet gear oil pump. I'll keep everyone updated.

Keep it up! We need someone to master the VQ oil pumps. Have you been following Frontline Fabrications project on the billet 4G oil pumps? Check it out on their facebook page if you havent seen it. You would probably find it very interesting.

I wish I knew more about these oil pumps and their characteristics and metallurgy.

I haven't checked them out. I've been off Facebook for a little while. Tired of seeing everyone's drama right now haha. Anyway, the gears are being drawn at the current stage. Most likely will be doing EMD with the gears as it will be more precise. They need to be +/- .0005, so not a lot of room for error. Pretty excited being able to get ball rolling after a few little set backs.


If anyone knows Josh Bloys, if you don't mind direct him to this thread.

Regards,
Jeremiah

Thank you sir. Definitely working on it! Sounds good, I'll have all the details once the drawings are finished and I have tested the pieces in the pump. I think you guys will be happy. I know I will be, means not spending 10k for completed drysump system haha.

You and a lot of us. I think without the billet gears the pump would be fine, but the extra security and not having to worry about the gears is also nice.

Sorry guys, things have taken a turn for the worst for a little it looks. The plan is still moving forward just not as fast as I'd like it.

I was in a motorcycle accident a few weeks back and broke my wrist. I have a good bit recovery to overcome. I do have someone working on the drawings for me while I'm down.

Thanks for patients and know I'm still working to make this a possibility.

Regards,
Jeremiah
