engine transplant on my e12

Danval · Post by **Danval** » Thu Feb 27, 2014 6:52 pm

Ok guys. So i got my monster engine out of my e12. Turns out its another engine. As far as i know my car is a 3.0, but the engine has a 3.5 casting in it. Like the cs or csi if im not mistaken. Anyway it was a torture to get that thing out of there. Specially by myself but i got it. Now. Im throwing in my m20b27 with the "i" head swap. So far i see clearance issues with the oil pan and sway bar. Ill let you people know how it goes.

Why go from an m30 to an m20 :S

Where are you located?

Better handling perhaps

The M20 is lighter.
Can't say that the M30 E12 is very convincing on hair pins. At least, mine isn't.

If you want better handling----> 3 series.
M20 vs M30 weight is not that much difference.

Wow.. not much acceptance apparently.. lol there are always reasons. Here it goes. I have an e30 im building for drift. Im throwing a mustang 5.0v8 in it. The e30 had the 2.7block with "i"head. Its low compression which is perfect because im going turbo with it. Reasons? I sold the really tired 3.0/auto trans. I want it for a daily driver and i kinda commute a little so less gas. I have all the setup for turbo, so as i get it running, ill start messing with it. Im located in south California

Beware. Calif smog will allow you to install a newer engine, though you have to meet the regs for the year of the engine, and be inspected and certified the first time at a referee. And they go over things fairly closely. No, very closely.

An e to i swap with Motronic 1.1/1.3 wouldn't be bad for performance or economy, but beware the BAR.

thanks for the advise. The car is a 75, last year exempt from smog check. And for boost yes, you are right im going with 10 pounds pnly, less than a bar.

Are you sure you didn't take out a 3.5L M90?

Either way, looks like you have been doing some work!

I think your swap would be intriguing. I disagree somewhat with the fact that the weight doesn't make a difference. It may only be only 100 lbs or so, but it is all over the front wheels and I believe you will feel in in the handling (you may have to adjust the front springs, it may sit too high).

IMHO, it is similar to the difference between a 528e and 533i...the 528e does feel more tossable.

Good luck with getting it to pass the emissions testing...

The difference between a M20 and M30 is 25kg.

Even moving the battery to the trunk makes some difference.
Having no AC as well.
But probably also would a good suspension.

It all helps but it still aint no 3 series which have a way better weight balance.
