Perhaps I will put an LS into my 318i and call it Ron.

Except this is a huge waste of time, because engines do not "scale" like that. If they did, then every manufacturer would build a hot little motor and upsize it, and they would all be based off motorcycle engines. But anyway, this thread has been done to death, you are flogging a dead horse. Just agree to disagree already! You don't have to always prove everyone wrong, you can just let them be wrong and take comfort that you are right (in your own opinion at least).

Ok, so is it you who sets this criteria that a performance motor is determined by kw per litre figures and only that? This maybe going around in circles but you consider the Chev LS7 to be in the same league as the engines in the Camry 4cyl, or Primera, or a 318i etc ie not a performance motor. Same deal with Chrysler Hemi 6.4 v8 at 355kw 55kw/litre MB 6.2 AMG at 376kw 60kw/litre LS7 roughly 53kw/litre. 7.0 litres and 373kw, 637nm torque and a flat torque curve from about 3000rpm. Red line at 7100rpm. Lightened internals. Larger exhaust and intake. Larger valves. Dry sump. Without sampling it I'd put money down on that engine being one of the most premium n/a performance motors of the past ten years (maybe of all time). Up there with M3 4.0, MB 6.2 V8 etc. By your reasoning the latest Ducati 1299 or KTM 1290 is less of a performance motor than the jappa multis for having similar power figures but using 300cc more?! Take both types for a spin the big twins are ten times as brutal down low and the same if not more up top as the (relatively) torque less jappas!! Anyway, long live high revving n/a motors of all capacities regardless of irrelevant kw/ litre figures!

Hi there, I was asked, nay instructed, to introduce myself so here goes. My actual name is Ian. I plan to do a bit of maintenance on my car so thought I'd tap into the wealth of wholly accurate information on the internet, then joined here to help sift out the stuff that is actually useful. I've come back to BMW after last owning a BMW 2002ti in the 80s. I've now got a 2003 330i Touring, very nice in Mystic Blue. If anyone knows who owned BRE 179 previously I've got a selection of their CDs which were left in the changer and which I'm happy to hand back. My musical taste leans away from Barbara Streisand and towards Radiohead. I guess I need to add a pic of the car at some point.

The 6-pot cars do use more fuel, but are generally more powerful. If you're regularly travelling longer distances the fuel consumption difference will be less significant. I prefer the 4-pot cars. They may run out of breath earlier than a larger capacity 6 cylinder car, but the balance of the car is better, and handling improved as a result. (And if it is important - a 6-pot will cost more to service due to having 50% more cylinders. )

You'll need to get the key enabled so that those functions will work. Each key will have a number associated with it so take all your keys and car to the dealer and get them to add the new one and delete any old ones.

I've had my E39 M5 (ex UK) airbag replaced today. I contacted BMWNZ about a month ago and they advised me to contact an authorised dealer. It included a new cover and emblem. So I'm a happy chappy.
