Which variant N63 do I have on my 2018 X5?

CARBONBLKM3 · 02-28-2023, 12:27 PM

Hey guys, I recently acquired a 2018 X5 50i and I wanted to know which variant as there's been some convoluted information while doing research. Is it the TU1 or TU2 since I have the final 2018 F series model?

X5 xDrive50i (F15) 2014-2017 N63B44O1

2014- X5 xDrive50i N63B44O2, 4.4L V8 Twin Scroll Twin Turbo with Valvetronic

N63 Engine iterations & the changes made to the N63TU vs the original N63 engine:

Thanks, I saw this graph, I was just curious if the variant came with the twin scroll turbos. Looks like it came with the valvetronic turbos instead manufactured by Garrett.

CARBONBLKM3 pretty sure you've got the twin scroll turbos.

Have you done any mods to your 50i? Was thinking about getting a tune, but don't want to run into any reliability issues down the road as it's my DD for work right now.

Twin Scroll turbos came with the N63TU2...the F15 never got that engine...only the new G11/G12 7 & G30 5 series that were produced during the model years 2016-2019 (check the BMW tuning link).

Cosmetic only to-date: PPF headlights, splitter and diffuser. Getting ACS lowering springs and spacers installed in the next few weeks.

Not tunes it yet but if interested, speak with Ben r33_RGSport. He'll show you the way to the promised land.

I'm UK based (American ex-pat) and leaning towards a custom remap with Evolve Automotive. Imran@Evolve
