100,000 mile report

Killerfish2012 · 11-07-2012, 10:24 PM

2 days ago............

My car was an '07 without an oil cooler, and I started out tracking it bone stock like that. I slowly modded it, but every year, I did several track events. I feel I've really, really driven this thing hard at the track. In addition, it was daily driven in stop and go/highway conditions, with temps ranging from -10 to 105F. Before my cooling mods, my car hit 290F+ oil temps routinely. Oddly enough, the OEM engine, Trans, and Turbos are SOUND at this mileage. A testament to what taking good car of your vehicle can yield. I can't say enough about this engine! I know for sure that if I had gotten an E90 M3 (S65) and driven it the way I did my 335I, there is no way I'd make it to this mileage without replacing either the Main, rod, or crank bearings. So guys keep on tracking your N54's. They are SOLID, and loads of fun. I may never let my car go, however, I will start thinking about it after 150K miles

Thanks for the report! Wow you've done a lot of cooling mods.

Nice pic, it's rare to get it at 100k even.

Thanks man.

You've got some nice mods too. I love your LSD. I waited to do it last, and next year, I'll be rocking one at the track.

Nice! Glad you are enjoying your car so much!

BTW what makes you think an M3s motor has a weak bottom end?

Bottom end might be solid, but they are having a lot of issues with rod bearings, due to oil starvation at the track, and the high rpm redline.

Same here. 98k miles now, 20k with tune, 15 DEs this year, everything stock, have stock OC, no cooling issues or any limp modes even once this year. As far as the engine/tranny goes, I'm quite impressed with how bullet proof they are at this mileage. And the engine actually feels to run smoother after these DEs for some reason; maybe higher air flow cleans the dirty crap out of the system or something.
