sadly my 135i probably owes me enough that I could have had a 1m

Very nice example! That tune typically makes 650whp, so probably even more than 700hp at the crank!

DCT? pretty sure your 2013 118i is 8HP auto and the only N55 with DCT is from the M2, the rest are 8HP. I only know of people swapping the N13 to B58, but I guess if that has been done then N55 should be do able, wiring part shouldn't be too bad though, some coding of certain modules might come up.

My work mate has a 2014 X3 M Sport with ridiculous 22 inch wheels and wants the OEM ones. Style 368 Anyone got these in the South Island?

I've seen bad boost control solenoids cause the over boosting issue, but you say they are new. Are they OEM Pierburg brand or aliexpress specials?

Nice!, definitely need that LSD!

I'm being a bit over the top with my F20 116i and changing every 6000km. I'm using OEM BMW filters and Castrol Edge 5w30. Turbocharged engines cook the engine oil pretty quick compared to old NA engines, well especially when tuned too.. haha

The one they call "Track limited" is fully catless. Unlikely to be caught tbh.

It is a little silly haha Its funny when a Dodge Hellcat Redeye with massive slicks etc, massive burnout does 11.9 and then I do 11.1 with a tiny burnout and transmission mis shift slowing me down lol

Although I own an N54 car and love it, not sure i'd recommend it to a buyer that wasn't good at DIY and if you're good at DIY the warranty is pointless. Just my 2c.

Yesterday I went back to the Drag strip with the intention of hitting the 10s. My car now has direct port methanol and is sitting around 600whp, I also got some 275/40/R17 Hoosiers. First few runs were OK, but my 60 foot was a bit average. Finally when I started working it out my trans decided it doesn't like this power level haha. So I managed a compromised 11.155 @ 125.6MPH You can see the issue on the 100-200 etc from dragy, transmission miss shift 3rd to 4th gear. I am going to install a sonnax zip kit and go custom tcu tune with Rod Sutphin and try again late January. VID_207160423_071904_851.mp4 VID_20241118_145206_992.mp4.mov

Managed 11.155 @125.6MPH this time, but transmission wouldn't shift from 3rd to 4th, so could have been a 10.

I tuned mine with MHD, you can easily buy this online and buy an MHD WiFi OBD adapter to connect with the phone app. My 116i now does 0-100 6.29 and 1/4 mile low 14 on my dragy. Stock was 0-100 8.7 and low 16 quarter mile.

Also the whole N54 vs N55, thing, both have similar issues regarding valve cover, oil filter housing gasket leaks, sump gasket, etc. N55 has valvetronic issues that can cost big $ to fix, N54 has injector issues that cost big $ to fix.. Both are potential money pits, but getting a newer 2014+ N55 is still more sensible, N54 is getting on.

EWG M135i model has a better electronic wastegate turbo and slightly bigger compressor wheel. If Manufactured late 2013 + they are all this type. The Rod bearings were also revised. Go for an F20 M135i or F22 M235i with the ZF8 as a good reliable option. (All M235i are EWG) Just make sure you upgrade the plastic charge pipe to a metal one, as they constantly break now days even on stock tunes.
