I've always thought it'd be fun to have bought a 3.0 X5 (or now X3) and turbo the crap out of it like the 3 series guys do. What I didn't know is that the 2.5/3.0 were harder to FI than the 2.8/3.2 engines...then I found this guys page today - E46 Turbo 330Ci ZHP » Turbocharging your E46 Non-M

I've written him with my idea and asked for advice on what'd be best...finding a manual E83 X3 or E53 X5 and go full turbo on it. While the E83 X3 is lighter, I've driven one before and it's far cheaper feeling and looking...but lighter is key if I wanna go faster. Either way, just talking and throwing out ideas.

If I had an extra 6 grand I'd just throw the ESS supercharger on my E53. Reliable, daily driven capable power.
