Racer Rog 1 Report post Posted April 12, 2017 Have a 528I wondered if anybody has done the m5430 crank rods and piston swop, have read about useingthe m54 inlet cam (single Vanos) have looked at a newer car but have spent to much time and money to get the one I have so far, plus a newer one does not seem to be as good as the E39's Quote Share this post Link to post Share on other sites

Blackie 510 Report post Posted April 14, 2017 Have a search on youtube. I watched a good video about it on there. It was M54B30 internals in M52B28 which I think it what your after? Quote Share this post Link to post Share on other sites
wrs 120 Report post Posted July 3, 2017 I did similar about 18 months ago but M50B25 non-vanos instead. The M50 vs M52 is dimensionally the similar so what I learned should directly apply to what you want to know. Here's a link to the project: I wouldn't think you'd get much improvement with just the displacement increase - you'd need to do cams and intake work to get the best from it. The M52B28 comes with pink-top injectors so you should have enough fuel for anything NA you can do to this engine... I got reasonable results but still need to do a few more changes and re-tune to take full advantage. 1 Quote Share this post Link to post Share on other sites
