BMW e21 323I 1981 LHD m50b25 swap

Post by D.schantz »

Hi, I`m doing a m50b25 non vanos conversion on my BMW e21 323I 1981 LHD. Am using the original gearbox, flywheel and engine mounts. I`m using e28 535 rubber mount on the left side and e21 323I on the right side.

The problem is the intake and the brake booster. Has any one done this before with a LHD and can give me some tips. Can`t find any thing on google.
Have tried with m52 intake.

Best regards from Norway.

Sorry for my English, its not the best :?

Your English is good enough! Nice project plans, I'm no expert on the topic but I'm looking forward to seeing more of the project and hope you can get some decent advice here!

Could a universal style booster be fitted nearer the fire wall?

Not sure if this will help out but a quick search:

Good luck

Hey, just noticed this thread, thought I'd give my 2 cents.
When I dropped an m50 in my e21 (Left hand drive), I used the 323 drivers side mount with a e36 rubber mount and some washers to gain height and tilt the intake manifold away from the brake booster. On the passenger side I used a mount off an e30 (I think, it was just in a parts pile, it's a steel mount rather than aluminum), to get that side of the engine lower than the 323 mount puts it. Ended up getting the engine at the same angle as it would be in an e36, and used a e36 transmission to match.
