Modified oil pan

[george graves]

No one's said it so I guess I will....dry sump?

not sure exactly how a dry sump works, and for shortening the pickup think i could just cut a half inch out then weld it back together?

In a nut shell, you remove the oil pump and drive a pump off the crank with a belt. Then you can cut the pan to almost nothing, you just need room for a pick up tube and for the crank to swing.

I like you plan of cutting the oil pick up. But how are you going to get your capacity back?

In a dry sump setup works similarly to stock. Your oil is stored in a separate container instead of your pan and you can generally place it in any location. Youll need an external pump rigged up to pump the oil from the container into the original pickup. On the other hand, the length that is cut off of the oil pick up tube depends on how much you cut of the pan. Basically, The inside bottom of the an needs to be a specific distance from the bottom on the pick up tube. Make sure your weld or the welders welds are air tight because itll be a problem if not. Have you ever tried sucking water from a straw with a pinhole in the side? No bueno.

He can restore the capacity by welding an additional box/chamber on the side of the shorten pan. Itll basically look like the added oil capacity pan muscle car guys use from moroso.

anyone have a clue one that distance from the pump to the bottom of the pan? i want to go roughly 1 inch lower so if i cut 1inch out of the pump then i could raise the pan that much

Yeah, thats pretty much what it works out to.

i was gonna try cutting my old sump pump from the e36 and see how that works rewelding it cause its the same material it seems and thickness.

Im sure you can do that as well, the only problem I can foresee is that the stock e36 pick up tube bends in the opposite direction I believe? Itll probably be easier to just mark and cut the e34 pick up tube to be sure.

i meant just to test weld on it to make sure it can be cut and rewelded properlly instead of buying a brand new one and screwing it up. Then once i know it can succesfully by cut and welded and i figure out for expanding the pan i can do it

keep us updated! i'm interested if you u follow threw with a good modded pan and pickup.
