2007 X5 4.8i Turbo

[bubela]

spend it on beer, weed and getting laid like a normal teenager. You only have your youth once.

haha.. I've never smoked weed or had a sip of alcohol, but I second this!! ^

Especially when compared to putting a turbo on the x5

yes I was gonna say that too, but then worried
He'd get high and get some "good car mod ideas" and do all of the above

Save your money for all the oil leaks that are coming....and air suspension failures, if equipped. And broken cooling parts. They are coming, and the oil leaks will hurt.

yep valve stems are gonna fail if you drive it like we are all pretty sure you do.... Valley pan, active ride, headlights etc

Even if you don't they go bad. I had 3 BMW's with a variant of this engine in them in my shop today lol

So basically this engine is bad in general? Should I just buy a new car?

N62 is bad mojo.

Turbo is going to be near to impossible.

Nitrous? Sure but also NOx gets the lifetime award for "most likely to have a young driver spin off the road and smash into things".

And just... N62... not good. Although maybe spraying a ton of Nox and meth through the thing will at least keep it de-carboned... But won't help the crappy valvetrain / valvetronic issues they tend to have...

NOx is really only an issue in CA and states that adopt California ARB emission regulations

Just enjoy what you have for what it is. When you see lots of oil loss...just sell it and get something more suitable for modifying.

Ha ha iOS corrected my NOS to NOX.

OP - yeah dude keep it - it's a good driver until the time you run into harsh maintenance issues.

interesting read

Just bought an '09 4.8i... am crushed. Was hoping I could turbo without getting the xDrive50i. Am I correct that boost is only available through Supercharger, and not really worth it, or?

Just get a 50i, it's like maybe $5-7k more, and comes with a nicer CIC infotanment system and the nicer LCI bumpers etc. It'll be way WAY WAY cheaper than properly putting a turbo on an originally NA engine. Hell, even a 35i is as fast as a 48i stock, and put a tune on the 35i and it's way faster. The LCI E70 X5s are really a huge jump over the early E70s when it comes to drivetrains.

All of the 50i cars are hands down the best bag for the buck right now. You can get a 750li for under 20k. A tune only seems like it makes 550ish whp

They totally suck on maintenance, like any BMW V8 ever made, but they definitely put up some big numbers with minor tweaks.

yea I figured as much. You know any of the big ticket items? I think I'm going to buy one soon lol

Valve stem seals have sucked forever on the V8s (N62, N63, N63 TU). Seems to be a ~40-90k mi sure fire failure. Turbo coolant lines like to leak and are expensive as hell for OEM, but I'd probably just replace the rubber bits with silicone and hose clamps if it were me. Turbos tend to live about as long as on the I6's, so 100-180k mi before WG rattle or bearings let loose.

N62s had leaky alternator bracket gaskets, made a huge mess, not sure if N63s have the same thing.

Other than that, the usual BMW things - valve cover gasket, front timing cover gasket, crappy water pumps etc.

So you're saying they're a big ole pile?

As much as any other V8 powered BMW - yes. This is nothing new, been this way for 25+ years.
