  2. [MOD] 323i -> 330i Intake Manifold + Tune-ish

    General E46 Forum
    Hi everyone, long time lurker but I now have something to post so here goes. I own a 2000 323i E46 (some 246,000kms) with an engine that's in tip-top shape, no oil consumption whatsoever, no nothing. I had the classic misfire issues caused by vacuum leaks and a broken PCV system, but other...
  3. M54B30 from a 2004 330CI into a 2002 330CI

    E46 Engine Swaps
    Hi, I want to swap in a motor to my 2002 330CI. It overheated and the head bolts stripped when I replaced the head. I can buy a good M54B30 from a wrecked 2004 bmw 330CI but I don't know if it will transplant easily. Is this just a drop in replacement or are there significant differences between...

    General E46 Forum
    Two years ago my brother-in-law and I swapped the trans in our E46 330i from an auto to a 5 speed that we took out of a junked 330i. He did 95% of the actual work while I played around with an OBD2 cable and a suite of BMW software I got from Romanian eBay. The car works perfectly (outside of...

    General E46 Forum
    Hello all, I'm researching and doing my homework with the intention of attempting to do the 6MT swap myself (from what I've read/seen, and the projects I've completed myself on this and my other car, I believe I should be able to handle this).

    Hey guys. New to the forum, not new to BMW's. I have a 320i Touring with the 2.2L motor. I have the opportunity to grab the full intake off of a 325ci. So I'm wondering if there are any sizes differences in the 2 manifolds and/or throttle bodies? If there are, i'm definitely not expecting...
