Matth5 471 Report post Posted May 2, 2020 I'm not convinced baffles are enough on their own, it probably wouldn't be enough for me to be comfortable going all-out on the track in mine again. The M2 has a dual oil pump design. This thread is pretty good, he ended up adding an Accusump:https://bmw.spoolstreet.com/threads/addressing-n5x-oiling-and-spun-rod-bearings-accusump-installed.4034/ I'd want either a retrofit with something like the M2 system or an Accusump. But I think I'll wait until I can get an M4... Turning a non-M into a track car ends up costing you as much as buying the M version, and you're left with something that's worth far less from depreciation... With my luck you'll probably see a thread from me in a year after my new M4 engine seizes on the track. 1 Quote Share this post Link to post Share on other sites
Herbmiester 923 Report post Posted May 2, 2020 Matt, I can see where your coming from, its a lot of cash if it goes pear shaped again. I was keen to make my old E46 a track-day car until I read a journal about a guy who did just that, the M54 failed on him twice, oil pump and something else I cant remember. His conclusion was buy an M car that's what they are designed for. Quote Share this post Link to post Share on other sites

A very excellent read. I wonder if the n52s suffer the same issues, or only to a lesser extent as they would likely be going slower. Quote Share this post Link to post Share on other sites

I reckon it'll be a lesser extent but not by much, you can still enter most corners at a similar speed. Just your braking won't be as intense. The more powerful cars go faster in the straights and brake earlier, but your cornering speed is similar, since that's all about grip (and how bold you are). I do suspect the B58 in the F series and Supra might be better. Since the Supra is advertised as a track capable car. But I'm not confident enough to put my money on that. I started a thread on it on one of the bimmerpost forums to see if anyone had much experience:https://f30.bimmerpost.com/forums/showthread.php?t=1712582 Not much in the way of technical stuff, and the same guy from the Accusump thread above commented, and he doesn't think it'll be any better.
