Yes, a 4.45 and 5 spd. It's a standard config for 520i 12V here in Malaysia. THe 3.91 from later M50 engine would be too much work for conversion.Originally Posted by bimmerd00d
I just gotten a right diff (i hope)with 3.64 ratio. Now, i am hoping the 3.64 can be fitted bolts on. And, what pros/cons will i get from the new ratio.
Is yours a M20B25 engine? What's the diff ratio? Is there any diff part no to identify the diff?
