I'm currently setting up a drysump for my rb30/26 vl commodore.

I got a peterson r4 pump for quite cheap, i just dont know where i can mount it.

I've attached some pictures of it in a hope that you guys can point me in the right direction.

I want to have 3 -12 scavenge stages in the sump and one -10 scavenge from the head.

-16 to and from the tank, and -12 to the block. BUT I THINK the scavenge inlets are on the wrong side,

cos when spun clockwise the pump looks like it pumps the wrong way.

?? any ideas ??

i figured out its a bellhousing mounted pump, i still cant work out how to fit it as a side mounted pump.

Bringing the thread back to life, does anyone know if you can fit a 6 stage dry sump pump to an RB26? Has it been done before? Pump will be mounted on a bracket where the air-con. was originally fitted.

Why are you wanting 6 stages Mike? 4 is enough for 1 x head and 2 in the sump, plus the pressure stage.

As a general rule you dont want to scavenge the super hot foamy oil from the turbo's either as its not good for the scavenge stage. Instead letting that oil return to the sump via conventional means so it can cool down and release air bubbles.

I'd like to have a try mounting one where the power steering pump is, drive it off the exhaust cam gear, and go with an electric power steering pump.

There are some second hands pumps available at good prices that are 6-stage. I was thinking 3 on the RHS of sump, one at the rear and one off the head and obviosuly pressure.

I have read exactly what you have just mentioned about sucking in foamly oil, etc as there is not enough to scavange having so many stages. In between my previous post and what I have read since I do not think it is a good idea.

I do not actually think a 6-stage will fit, I think it will hit the engine mount which ever side you put it on. What you suggested is a good idea too, only thing is you are scavanging from higher up.

Cheers for that Ian, how many stages do you have on your VW?

[GTRNUR]

The pump on the bug is 3 x 1.75" scavenge stages and 1 x 1.25 pressure stage. I use a -16 from the sump and 2 x -12's from each rocker cover.

Having re thought it... even mounting an oil pump where the power steering pump is located would be tricky. Available room is at a premium and clearing the turbo intakes, plumbing etc would be a challenge.

I am in the process of fitting a Peterson 5 stage dry sump kit from "dazmo"

There is still a bit of room behind there. The 6 stage will fit but you will have to block the front turbo oil return hose and tee it to the rear if required.

A small plug for dazmo; his dry sump kit is fairly well designed, packaged and priced. I am impressed with the quality.

[bigmikespec]

Yeah "dazmo's" kit is proven in his own car no doubt quality combination... I have annoyed him a few times asking some Q's!

this is my 5 stage one. as you can see there is not enough room for it to come back any more because of the engine mount.

this is with a highmout single turbo, stock twins,no chance of fitting.

depending on how the last section is, you may be able to fit it, but i doubt it.

There's plenty of room with a Peterson 5 stage. I am sure you can squeeze another stage into there but the oil drain needs relocation.

mount it on the bonnet & run it on a gilmore drive - modern day MAD MAX!

Thanks T04GTR I was waiting for you to post! Do you have any details on your sump mods? I understand if you want to keep it close to your chest, feel free to PM me. Cheers.
