0-60 & 1/4 mile times on a FBO X1 35i

[Cabra]

Considering an X1 35i and going FBO. What performance numbers can I expect ?

You also need tune what do you consider bolting on? Down and charge pipe... intercooler etc.

Some folks have gotten into the mid 12's

This thread has some useful info:

Btw, the best I've read of for a stock turbo N55 X1 is 12.1 @ 111. An upgraded turbo is needed to get into the 11s.

JB4 tune, downpipe, charge pipe, FMIC, trans flash

With that... about low 13's

I ran this set up no intercooler for a little while. Used jb4 93 octane Alpina trans flash...I recall about 13.2... felt I didn't want to just run straight so I refocused on suspension and tires to track and autocross... since 2018 gave this X1 to my daughter.

It's a nice platform to mod and overall great little vehicle. With 110k miles my daughter loves it

Besides a water pump, what kind of maintenance and unforeseen repairs have you had to do?

[cwickberg]

Oil leaks... oil pan gasket, oil filter housing, radiator leak/ replacement... charge pipe failure...sun roof headliner

These are known issues... none are catastrophic. All have been repaired except headliner... that's too much hassle to fix
