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

[A.J.]

I can do the subframe for any rack, but if the mounting is different (obviously) I would need you to send the rack with and I will make mounts for it. The price right now is 600 dollars un powdercoated, plus return shipping.

As far as the different pans go, etc. I will have to ask Sam (lag) to respond to that because Im just a fabricator and his is the first BMW I have ever been involved with.

$600 for frame and oilpan...or just frame? Thanks....

Can you make the steering rack mounts smaller to accept the E36 rack without spacers? Seems to me that anyone doing the S54 swap wouldn't be running a stock E30 steering rack with the 4:1 ratio, or even the stock M3 3.5:1. I have an E36 3:1 rack in my car and would want one less custom part so I'd have the subframe sized for the E36 rack... Thoughts?

What other advantages does this provide over an E34 pan? Seems like $1k is a lot to spend on a setup that will be quite custom, when an E34 pan and pickup is $100 and bolts right up to the S5X engines... Don't get me wrong, I'm interested and in the market for one of these right now so I might buy one, just want all the details.

Mine did fit and, but since I have M3 I don't have the oil level light on the check panel.

[BeirBrennerE30]

ok weird question. If you keep the dual sump pan (s50b52 or s54) does the oil level sensor bolt in and function still? and if so does it still fit after the modification? I dont remember where my s54 pan went to check.

[Mr. Horsepower]

I have my swaybar in front of the steering rack and adjustable endlinks, on M3.
I have the TMS endlinks, but I probably need to make them longer to get the right angle.
My oilpan and subframe is modified.

[Lag]

No, my swaybar will be mounted in font of the steering rack. What I meant was the end of the swaybar ends up close to the same position this way as compared to the stock configuration.

The question on the standard S50 pans will need to be looked into I am not sure on this, if anyone has one that they would like me to test fit please let me know and I will do it. Otherwise I could take measurements off my e36 and compare that to the set up.

Subscribed for talk of stock S50US pan clearance.

Yes, you could mound the sway bar 180 degrees around and it would bolt up the same way. My car is an M3 so I am using adjustable end links and they will work fine. Do they make adjustable end links for non-M cars? If so they should work as well. The sway bar placement is not too far from stock and that's why adjustable units would be best.

Lag, if I understand you correctly....on your car, you're keeping the sway bar near the original position [on the modded subframe] and not flipped 180 degrees? I plan on welding tabs on my strut carriers to utilize the M3 adjustable end links....

thanks!

Gorgeous headers. Where did you source those? Cost? Looks kinda like Kromerkrafts... do want. :)

[Lag]

I THINK you the new clearance is a couple of inches but I am not sure. Basically the E34 pan hangs well below the subframe and with this set up the sump is about .5" higher than the subframe. I would also be willing to bet the overall thickness of this subframe is less than the stock unit resulting in more clearance.

I have not tried any other headers on this set up but this subframe is smaller dimensionally especially where the headers pass through. I would think, based on the minimal amount the factory frames have to be modified, that the stock headers (euro s50 or s54) would clear this. If someone sent me a pair I could test fit them. I do not have any stock headers laying around.

Still very interested! Is the front swaybar mounting just a mirror image of the rear mounting (bar turned 180 degrees)? You mentioned adjustable swaybar links; do you use M3 style links that mount to the strut carrier?

This looks interesting, but I would say it is a very very much more difficult way to do it compared to how mine is done. I assume you have seen the pics since you used one of them above here.

How so? this way the subframe is all reinforced and much stronger than the factories, and when the pan is notched and sumped it provides more capacity and plenty of clearance. We're happy with this way

When that is said, how is the weight on the sub frame you are making compared to the stock one?
Also, there would be a benefit to have sway bar mounts both front and rear. So if you are going to put in an E30 engine later, you will not have to change the sub frame.

subscribed so I can find this later. Can anyone confirm that the s54 headers clear the modded subframe?
