My 318IS after buying a mates crashed 325is so I've decided to drop in the m20 b25 into it. I'm contemplating fitting the m tech2 kit but not sure on it yet as I like the standard look of the IS. Also trying to decide whether to use my 4.1:1 lsd or the 3.91:1 lsd from the 325 but will wait till I get her up and running to decide that. I've never done this swap before so any help and advice is welcome hope these photos wrk as haven't uploaded pics to this before
