There are a couple of kits for the E46. I don't know of one for the X5. Block should be fine if you stay around the boost on the E46 kit. If there is a problem it is more likely to be piston ring blow by, valve guides or head or intake gaskets that have deteriorated. If you purchased the kit the tubing and mounting brackets might not work as they are for an E46. It would also be necessary to have the engine custom tuned for the turbo.

Also, do all of you get your parts from Dinan? I saw the brand thrown around a few times in the forum and was wondering. Has anyone got some advice for upgrading the 3.0i, because i've been told that I might as well just blow the engine up as is, because changing anything about it will diminsh the life of it heavily

The m54 is very stout. If it's tired refreshing it will bring it back to form.

Most of the Dinan stuff is no longer available from them. Anything short of NOS or FI is going to be wasting money performance wise. Just not much to be had from intake, exhaust, and programming unfortunately.

So how would I go about forced induction without doing damage to the block and cylinders? And would it be turbo or super?

i would love to add super/turbo to the M54. love the engine, and the truck but if i had even 50 more HP i would be much happier.

I feel you would be very happy with a 4.8is.

I've driven 4.4 and the power level of 4.6 or 4.8 I'd be happy with. I HAVE (2) M54 E53. I'm very happy with the engine other than its short on torque.

Come on, you know you're not really wanting to get rid of yours are you?

Although it would keep Andrew's yin & yang color collection in order [emoji848][emoji1787]

Andrew, you would just love the 3.0d. Same horsepower as the 3.0i with the same torque as the V8... :thumbup:

And unless you drive really fast (and as our speed limit is 100kmh, I don't) it's the best of both worlds.

But for real top-end speed.. the V8s have it in the bag, hands down.

I'm much more interested in torque v but the USA has shunned the diesel.
