mmm-five said:There are 3 different power levels from the 3.0 engines (215bhp, 228bhp and 261bhp).
The e86 coupe was only available with the 261bhp N52B30 in the 3.0si cars (this was also available in the 3.0si roadsters).
The e85 roadster had the early 3.0 M54B30 with 228bhp from 2002-2005, then the 3.0 N52B30 with 218bhp from 2006-2008, but also had the option of the 3.0si version with 261bhp from 2006-2008.

Who buys a 3l 6 cylinder convertible roadster and doesn’t rag it ?![]()

I have the N52 in my E89 and not only has it got good performance but the fuel economy is equally good, I am getting around 24MPG in town and on a long run over 40MPG, never achieved anything close to that from my E46 6 cylinder.
