Hey guys, Here is what's happening. I've managed to get my hands on a dry sump pump , tank and the accompanying parts. I want to use it on my 20B ( street/track ). Yes I know it's overkill, but here is why I want to do things this way.
1. I don't have to buy a subframe.
2. I'm going to be pretty low to the ground
3. I enjoy being diffferent
4. There is a reason they use these on dedicated race / factory supercars. They work

I don't remember where it was I saw it but I did do some searching and I can't find the thread. But, someone built their own dry sump system for a P port 13B and if they can do it so can I. But there were some pictures of the oil pan( plate) and I can't find them. I had intended to use them as a template for my build. Any help would be appreciated.

 

You want some pics of front covers that have been modified? I have a couple with scavenge tubes I can show you.

 

Yep, that would be a great start.

 

I found the thread I posted them in a while back, faster than taking new pics tomorrow!
Here ya go: https://www.rx7club.com/showthread.p...mp+front+cover

Let me know if you want other views.

 

this looks easy enough.. so basically find some aluminum bungs drill some holes and use copper tubing for the scavenge tubes. Very basically.

 

I know not the main objective of your post but if you go dry sump on a 20B it drops right in to a FD without the need for any other mods (mounting wise)?

 

Hmmm I'm really liking the modified front cover.

 

this may be a dumb question but, would you be able to use a P.S. pump as an external oil pump? would this even flow enough oil? just wondering.

 

I think power steering pumps are more of a low displacement/ high pressure design. They don't move a lot but build high pressure.

 

Correct! I had thought about this years ago, but after researching and testing found that the OE ps pump on an s6 puts out 1300+psi..... that's a little to much oil pressure

Hey Slevin, what make of external pump & setup are you intending to use, I am looking to do this also - only 13b REW, trying to avoid the expense of the mazda factory front cover etc

Cheers

 

Pick one off ebay, any of them will flow more than enough oil. Depending on how you want to scavenge a two stage would probably work, three would work for sure(one pressure, two scavenge).

You could use a two stage and just have an external manifold to bring them together before the pump.

 

Would it be possible to get a diagram to show layout of say a 3 stage, Pressure feed would feed into the rear housing in lieu of oil filter housing, I would need to run a remote filter in the pressure line.

Any details (Pics) would be great.

Many Thanks.

 

If you've seen the pictures I posted in the thread I linked to I can just describe it to you faster than I could draw it in MS Paint.

Coming out of the front cover, each port would feed a seperate stage of the pump on the scavenge side. These two stages can be brought together into one big hose to send the oil to the remote tank. The tank holds the oil and has plates in it that the oil falls through to help remove the air bubbles.

The oil comes out the bottom of the tank and goes to the pressure stage of the pump. Out of the pump and through a filter, coolers, and back to the main oil galley.

On the rotary you can bring the oil back into the stock location and either plug the hole for the stock regulator or use it(the pumps have regulators in them that are adjustable). Or, you can skip all the right angle turns and bring the oil back into the front plate and stock oil filter location.
