Oh and another thing, your 4.6, now is that engine the same as the 4.4 just a bigger bore? I was trying to find out the differences between the 4.4 engine and 4.6/4.8.

That and what the difference was between the m62 and N62. I am getting an itch to get a 4.8is, but wanted to know if the engines were the same, just a bigger displacement. If you have any thoughts, let me know.

Thanks.

120K miles it is high time. I was planning to do it in December but ran out of time and decided to go on a 2K mile road trip to OR and then skiing in CA.

4.6 is built by Alpina based on the 4.4i M62 engine, so yes it has more bore or stroke or both, plus different cam tuning and a different vanos set-up too I believe. All told it is good for another 50hp.

4.8is motor may be built by BMW - not sure about those, other than the motor is slightly bigger, they get slightly better mpg and make another 10hp over a 4.6is.
