Default IX 32v swap

I just had a *REALLY* bad idea...

While putting an M60 into an E30 has been done, it isn't terribly easy.

One of the largest hurdles is the oil sump packaging. Since the V8 is shorter in length than the I6's and still has a front sump, its sump wants to be where the E30's front suspension crossmember is. This can be remedied either with an Alpina oil pump and pan (expensive and rare) or with significant custom fabrication.

The situation is worse in an E30 iX as the front crossmember was moved even further forward to accomodate the front drive hardware. This is the reason the M20 (and M50 in the E34) use a rear sump pan and convoluted pick up tube.

The X5's have had V8's for quite a while... they appear to go from the standard RWD front sump pan to a rear sump pan similar to the E30 and E34 AWD cars. This very handily solves one of the big difficulties with the M60 swap in a way that is uniquely enabling for the E30 iX.

Now if there were only an easy way of dealing with the brake booster... will the 7 series hydroboost clear the M60 in an E30?

you could possibly do it with an E53 X5 diff and oil pan, but I don't know what trans you could use. you wouldn't be able to use anything from a 325ix. Even the X5 stuff may not work because the axles have to be centered in a specific place. the E46 pan will definitely not work, so it depends if they both share a same centerline (the E46 wheelbase is longer).

I think X5's all came with xdrive, but I'm not sure. you could be stuck with a similar design as the E46.

I know you said you didn't want to pay for it, but I think an S54 would be easier, cost less, weigh less, and make the same/better power..

I should say that I *already have* an S62 in the shed...

I found a junkyard with an X5 pan for an amount I'm willing to risk on research. That will give me the bellhousing face to axle centerline distance.

Do you guys have that info for the E30? Thanks!

I think you will want to find a spare ix front subframe (not that expensive, there's one on ebay for $100 shipped) and go from there. you can rest the pan on the subframe and somebody can measure the distance from one of the bolt holes on the subframe to the axle centerline. should be enough info.

S62 is awesome. I think it would be a better fit in a larger car. But I can't say it's not worth thinking about - just that I wouldn't personally do it!

I already have the ix front subframe... I don't have an ix, but I've been thinking about playing with one for a while.

I bought the S62 intending to drop it into an E34 530i as an easy swap to make a gentleman's express.

you could always sell the S62 and buy a somewhat more feasable S54.

Didn't know there were remote boosters in E34 540's... E34 530's also?

Edit: Wild.

Didn't Alpina use something like this for their V8 E30? I always thought those were bespoke parts.

Edit again: If BMA's usual relationship with RealOEM's MSRP holds, I could get all these parts for <$200. Interesting.





Edit some more:
Using the V8 ZF 5 speed with the appropriate bellhousing, I could install the E34 AWD ZF rear case half (which lists for $280 and I'm guessing could be had for $150) and have bosses on the transmission for mounting a T-case.
