Tubular Front Sub frame and Custom Pan for dual pump set up

[etxxz]

i'm interested to see what you came up with.

how are you designing? are you an engineer? any FEA experience? It will be difficult to beat the stock one purpose/weight/cost wise. I understand the oil pickup benefits of the m/s54, but is all this really necessary. I'm looking at it from a cost/gains/reliability standpoint. Short of my oil pump nut 'failure', i haven't experienced oil starvation, pressure or foaming problems and i don't even have a baffle on my s52 track car.. though i should add one since i'm rebuilding it now..

Lag brings up different approach, could you add a link or pics?

We take the stock S54 or Euro pan and modify those.

Ohhh so you need a custom pan too? Which one do you modify, e34 or e36?

Hey Guys,

Thank you for the responses. The cross member retains the outer stock mounts (where the sub frame bolts to the car, and where the motor mounts to the sub frame) and is then cut and a tubular piece is put in place. When the stock center is cut, the end pieces are fully boxed, and then the tube goes through the boxed section and then is welded and gusseted. It is also reinforced by the engine mounts same as kits that are sold and it also has the sway bar mounts reinforced.

The pan is a factory pan that has the original rear sump removed and a new sump fabbed in place.

I will get pictures as soon as I have it back from coating.

Is this a stock modified, or, new fabrication oil pan based set up?

Interested. Please post pics.

i may be interested, but i'd like to see pics first. Both out of the car and installed. And a weight comparison between stock and the new part.

Hey Guys,

I am working with a local fabricator to build a tubular front sub frame and custom oil pan to allow for either a euro S50 or S54 pan and pump set up to work in the E30 chassis. This will eliminate the need to use an e34 pan and m50 pump set up when swapping in an S54, Euro S50, or to allow for a dual pick up for a US S50/S52 into an E30.

We have completed the first one and it is going out for final powder coating. The new pan has slightly more capacity that the factory S54 and euro pan and the front sub frame is fully reinforced. Another benefit is that the pan is not the lowest point of the car, the sub frame is. This is not the case with the e34 pan. We have created a jig that will allow us to reproduce these as needed and I am testing the waters to see if anyone is interested. Once I have the first one back from powder coating I will post pictures.

If you are interested in something like this please shoot me a PM. Thank you in advance!
