I didn't realise that these Accusump's were still around. They're good for racers with lots of clearance in their engines as they provide oil pressure to the engine BEFORE you hit the starter.

Got a link?

this is where i see them, I get bad ideas from random catalogs, and these guys have useful parts. Pegasus Racing

They have the elusive check valve for making oilcooler systems not drain ;)

Accusumps can also run in a mode where they supply oil if the pressure drops below a set level.

For the price much better solution for racing as for the street waste of money for an a to b car.

Though this does not look like alloy, it was sold by Datsun Competition for racing purposes. The pan holds 6 quarts of oil. The pan is baffled and looks like it has a windage tray. There were 2 part numbers listed, 9/6-H1050 for the B210 (120Y) and 9/6-H1050 for the 1200 and 210 (B310). Both pans were listed for $500.00 in my 1984 parts list. I have no idea if any are available.

Quote:Gary, I have broken your quote down to get a better look at the part numbers & I suspect a faux pas here as both numbers are the same & the 1200 engine should have a different part number as the pan rail is a different shape in the area of the oil pumps. The pans should be interchangeable on all engines from 1974 as long as it fits the A15 which has extra clearance on one side for rod clearance of the stroker crank.
So it should read something like,...

A/A BBBBBBB B110 /1200
X/X YYYYYY B210 [120Y] & 210 [B310]

That pan looks pretty damn serious to me & with six quarts [US] [5.6781 Lt] it should do the job just fine.

Yep, I blew it with the numbers, putting the same number in twice.

Datsun Comp must have it wrong also... As listed in the catalog:

9/6-H1050 B210 competition oil pan

9/6-H1052 1200/210 6 quart competition oil pan

The price list is of no help as only has "OIL PAN" as the comment for both part numbers.

I was not aware that there were shape differences between the early and later A-Series pans other than the rod clearance detail. The warmed up A-15 I built many years ago proved the point of rod clearance quite concisely. With the 1200 pan in place I found that the rods hit the side of the pan when I tried to rotate the crank by hand. Fortunately the engine was still on the stand...

Yes, the anomaly is still there, so for $500 in 1984 lets hope that they provided the right one.
This is a modified steel oil pan & if one was interested in performance above all else, then this would offer much more 'bang for buck' than the alloy one.
I only got mine because I'm a bloody poseur.

I have the steel Nissan Comp oil pan on my A15 race engine. The windage tray needs to be clearanced to clear the rods. OK with the shorter A14 stroke. I don't think they ever considered anyone racing an A15 because of the long stroke, but there are several in SCCA's GTL class today.

Hiya Guy's..

here is the Accusump link..
Accusump

I thought it was a great idea for the CHevy in the Jet boat we raced, and rally/race would be awesome, as oil surge can be a problem, when the pressure drops off, the accusump takes over, when pressure is back, the accusump recharges...
