X3 35i real sleeper

Well truth be told I am a previous e92 n54 with all the supporting mods making 400+rwhp, and when I got the f25 N55 I swore I would keep it stock. So my list of what I will be doing is below. Any advice good or bad please post up.

AFE intake
Vargas hybrid stage 1 turbo upgrade
Vargas crank bolt capture
catless downpipe
remus axel back exhaust
F30 aftermarket intercooler
upgrade charge pipes
JB4 or other tuner
oil catch can
valve cover breather
KW coil overs (megan racing way less $)
new coils and 1 step colder plugs
snow performance meth kit

flying under the radar is the most fun when you catch unexpecting sport car or so owners and show then what the N55 is all about.

this small suv is very impressive.

I was on the market for a 3.0T Q5, with a stage 1+ tune (415hp), until someone told me that the f25 came with the n55 and they are wayyyy cheaper.

My first impression was : "wtf, why they put so much performance in a such car?"

getting high 13 with a stage 1 tune on 1/4 miles , stock internals, is crazy fast for a suv.

zf 8 speed transmission is very smooth and fast. But nothing like my audi manual 6 speeds tho...


overall, very impressed. Even my friend didnt believe it.

-I have JB stage 1 on it, and probably put the JB4 laying in my garage ( I've just learned that it will work...lol).

- golf t mod.

and this is it. It's the wife 's car after all

yea same here the performance is better than I thought it would be. My X3 runs perfect and no need for a new one as the performance is somewhat the same once I do a few grand worth of mods

I did the following:
- AFE intake
- FTP Motorsport charge pipes
- new coils
- Sprint Booster
- RaceChip Ultimate piggy-back tune

runs great, surprises a lot of people with the power it has.

I did all but the charge pipes at the same time, so I dont have any data on the afe intake by itself, but I think it is worth it. Check the for sale forum, they pop up now and then for sale when people return leases.

upgrading to a catless DP makes a huge difference with throttle response and lag when I put the stock dp back on my N54 I was like holy sh%t this thing is a dog

The original BMW sleeper. Sorry no English translation. It matters little because the exhaust note is the same in German and English.

Got my ultimate racing down pipe from a forum member for a steal!

Anyone know if MHD map would turn off the CEL for down pipe to pass inspection?

Thanks

Don't get cocky if N20 X3's line up next to ya... They'll smoke a stock 35i with a Burger Stage 1.

+1, comming from a cable throttle body and manual tranmission, 0 lag.

Now, both my cars a electronically controlled... hate the lag. both are tuned to ''reduce'' the lag. but its not perfect.

really?

hard to find 0-60 and 1/4 miles time on these f25....

but a 6 inline with a twinscroll turbo, is very impressive even stock.
