Dry-sump setups tend to be pretty pricey and really are only needed by the most radical all out modified race cars.

im wondering maing things needed id really like to slam my car but the oil pan makes it hard cuz of how low it sits... plus this will end up being a track car if i dont sell my other E30 or vise versa.
the ? is how would i go about doing a setup like this? i think i could easily do it with parts i have at the shop.

Biggest parts to consider is the pump obviously, a remote oil reservoir, the -an lines and fittings for the plumbing, and a custom dry sump pan. The pump could relatively easily be mounted in the location of the ps pump or ac compressor.

would the stock oil pump be able to pump enough for it?

Stock oil pump is NOT a dry sump pump, it works by sucking out the oil from the reservoir, the pan. Then pumps it around the motor, a dry sump pump is external and is run off a small toothed belt. You have a lot of reading to do on the general concept first. Expect to spend about 2k if you buy either a cheap or used pump, and are thrifty with the rest. No corner cutting, just spending wisely. Any reason for a street car to have it? No. Race cars, it depends what you run and if it's really necessary got either starvation issues, or lowering the car/motor for a better cg. Not worth your money for expensive unnecessary bling. Oil changes are waaay more quarts than s stock engine holds too, so its also more $ there.

so i cant use parts off the totaled porsche at my shop?

[ExViTermini]

Nope, they're setup kinda different. The oil returns to the bottom of the case and the internal pump picks that up and sends it off to the reservoir and cooler and back around. Almost a mutt setup.

damn this should be fun to figure out lol

Stock pump is removed in a dry sump setup the pump is located outside the block, plan on spending around $3800. If you don't work at a race shop you likely won't have the components "laying around". I have most of the hard parts for an m50/s50 b/c I was looking at this route for my vert last year but I didn't want to loose the A/C on a car I can't really track anyway. VAC makes a kit that mounts the pump and provides the belt drive for it, but you'll still need a pan ($600), oil tank ($400), oil cooler ($150), Plumbing ($700-900) and remote thermostat($100). I basically got 30% done and decided the cost was not worth the clearance on a street car so I'll keep it for my track toy build.

I linked most of the suppliers I found/used below in case you have the budget and want to get into planning a system out like I did. PM me if you have any BMW specific questions the companies below can't answer.

^^ thanx homie!

we mostly have porsche shit laying around from rebuilds and what not, were not a full out "race" shop but we have built a few race cars and some other fast ass cars ill do some more reading.

[Justin B]

Um, I doubt it. Simple question, does it have a conventional oil pump inside the bottom of the motor? Yeah, well no bueno. That's regular wet sump style. Now, if this said porsche has something like this hanging off the block, with fittings to an external oil reservoir and a reaaaly flat oil pan that looks more like a valve cover, then maybe. This is a dry sump pump. There are diferent ones, but they ate all sorta like this. Nothing else will work.

Takes me too long to reply on my phone. Lol

lol it happens homie..
and yea that pump is fucking expensive as shit... ima pass on this shit unless a gift from god happens and i hit the lottery i dont play or we for some reasone get this guys E36 M3 race car back at the shop lol

Yah I was roughly figuring that 2k if you could fabricate your own parts, like the tank and pan. The pumps aren't all a mint, especially if you find agood used one. Search dry sump pump on ebay, mostly used prices, but under a grand. Puts you on all the fabrication and head scratching though. I want to do this for my 02s stroker m20 to simply avoid putting in new oil pump layshaft bearings, lol. 3.1l build, but never bought the sump parts. At least I haven't bought a new wet sump yet ;)
