parts list for m30 swap.

[screamingbmwe30]

anyone have a parts list for the e30 m30 swap? anyone on this board done it yet? thanks!

[george graves]

Not a compleat list but here it goes - there are other options, but this is what I used. You can save some money by doing it as ely did (user name rs4pro3)

e24 auto m30 motor 90k
Getrag 265 tranny out of a e30 m3.
e30 m3 driveshaft (shortened and rebalanced)
Shortened shift linkage
m20 rubber motor mounts
e30 m3 tranny crossmember.
e24/e28 ecu
89' m20 wireing harness (custom spliced)
e34 m30 oil pan
e34 oil pump (rebuilt)
e34 m30 airbox
custom motor mount brackets
e30 m3 tranny mounts
e30 m3 flex disk
e28 radiator
e28/e24 radiator hoses (and some m20 hoses)
Lots of cussing and swearing(not optional)


note. If you can find the right e30 driveshaft combo you don't have to pay for a expensive e30m3 shaft or have it shortened. (ask ely)

In compairson the m50 BOLTS RIGHT UP. M30 swaps are not easy.

or you can go to e30.de http://www.e30.de/335i/00.htm they have a wright up there too....

what kind of hp/tq do m30s make?

[Bryson]

George, I take it that you've personally done an m50 swap as well. Otherwise, that's quite the bold statement you've made there about bolting right in.
I'm not disagreeing, rather just making sure you've got it straight on what's involved
I'd like to check your car out some time, I'm in SLO about an hour and a half from SB
I'd like to do the swap myself some day, just because I'm curious about it, but I'm turned off by the weight and lack of advantages of an m30 over an m20. After all, there are still 12 valves, an AFM and a distributor :P

but 220 hp 8) stock

anyone know the weight of an m30 vs. m20?

look for yourself

edit: 220 crank hp can be obtained pretty easily with an m50 (m3 cams, 24lb injectors and custom software)

That looks like only the 3.5 liter stock has around 220.

Ok, maby a bit of a overstatment. But not by much. What's the partlist for a m50 swap?

M50
e21 brake booster(modified)
Bend heater hoses.
e34 m50 oil pan
ummmm....
That's about it right?

Lot less details to work with. Yes, I worked with M3 Ryan to do the swap. We made custom one-off motor mounts. If you can get ahold of the mounts from e30.de it would be a lot easier.

Since we were starting from scrach, We had to figure out things like motor placement. Try positioning a 300 lbs of oddly shpared motor into a tight space and keep it there well you fab up motor mounts is not a easy task. And no, you can't just hang it off a hoist. And it has to be DEAD on.

No, I've never done a m50 swap...so I guess I talking from only forum knoweldge.

Love to have you down some time Bryson. I want to check out your suspention set up.

The m30 motor is COMPLEATLY different than a m50. Different feel, different Hp and T curves.

All the old bimmer guys refer to a m30 and BMW's Legandary smooth inline 6. It's feel like a big m20.

The m50 is a totally differnt beast. If I had my way I would have gone with a s38. Now there is a motor! But the cost was too high for me,

What I am trying to say is you can't pick a motor based on weight, HP/ T numbers. M30? M50? they are apples and oranges.

[Bryson]

mmm s38
I'm all about non-vanos 24 valve sixes :P

put that money into the m30 and you'd still have more then the m50 ;)

[Bryson]

that all depends how cheap you get m50 parts ;)
hm, free m50 plus a few hundred in mods.... you'll be over 220 likely
