Clutch, LSD, Turbo...12' N55 need help

NORAGRETS · 09-05-2017, 11:29 AM

All,

Doing some work:

Clutch (slipping a bit) - need some advice on which brand to choose? BMW stock was always fine for me, I want it quiet like OEM clutch...but would upgrade if theres something better I dont know about

LSD (always wanted one) - Wavetrac, OS Giken, Quaife, M-Factory (not the recalled unit)...which to choose? Street driver/daily driver/spirited driver.

Turbo (because why not) - pure stage 2 looks like the one to choose. I will be doing LPFP upgrade and diverter valve/wastegate upgrade as well.

What other parts do I need to upgrade when I am doing these 3 major upgrades? Help pls!

If you want to go full e85 and get the most out of those turbos, I'd get a Port injection system.

Clutch 550i often gets recomended. OEM and bolt on.

Diff - Quaife. People will say "oh its an open diff if you cock a wheel", well if you cock a wheel on the street you're a bit of a... cock.
