I will need to modify the fan housing to clear the oil pump. I will also have to custom make some motor mounts.

you are one step ahead of me. i am doing the same as you. same pump also.....

i just finished all my case mods, and concentrating on building my sump tank.

did you hav to grind your cam bolts? do you remember how much you took off the snout of the pump?

i am going to use tangerine racing's horizontal fan set up, so my engine mounts shouldnt be a problem.

I ground about 2mm off that pump. Maybe more. I also made the tang have some angle at the end like the stock tangs. I made the tang length match the one I got from Raby years ago. I took a bit off the boss holding the drive tang to make sure it was clear of the cam. I probably took off 1mm at most on the boss.

I did grind my cam bolts to be safe, but I probably didn't have to with the ones Jake sent me.

What case mods did you do?

How are you routing the oil for the pressure stage? The galley from the pressure side of the pump goes right to the oil filter...

i used this diagram (IMG:http://www.914world.com/bbs2/uploads_offsite/i722.photobucket.com-12492-1328228312.1.gif)

and modified it to this (IMG:http://www.914world.com/bbs2/uploads_offsite/i722.photobucket.com-12492-1328228669.1.gif)

1. jaycee 3 port remote oil filter/relief @ 80 psi
2. remote oil cooler
3. sump tank

in my picture you can see i welded a fitting on the passage from the pump (where the old filter stand was)

then it goes thru the remote filter, oil cooler, and then straight to the mains via the oil cooler location. another welded fitting. i just cut of the the old cooler stand off the case.

Here are pictures of the pistons after going through the ultrasonic cleaner and then me balancing them. I used a 1g scale, a 1/2" drill bit, and an air powered angle grinder with a small sanding disk (just to clean up any sharp edges). The all are at 570g now. They were as much a 3g out. Weights ranged from 570g to 573g.

So how do you pump oil out of the sump?

I was thinking the same thing. Somehow youi need to get the oil in the tank to the suction side of the pump. All the dry sump systems I've seen have a scavenge and a pressure pump.

i know, this diagram was just for me. i didnt draw them in because i know that the feed and return from the sump tank go to the oil pump. this diagram was to figure out how i was gonna get in and out of the case.

Been cleaning parts like mad. Finally ready to close the case up after checking the fit of the drive tang and boss on the CB dry sump pump.

I also got around to modifying the oil filter housing. I used a slide hammer with a small, blind bearing pull attachment and removed the bypass system. I then cut an AL slug to fit and MIG'ed it in.

With regards to the tank, I'm using a very nice Patterson tank that Blake sold me. I'll be mounting it up front and trying to figure out how to mount an oil cooler up there too.
