I've been chasing a decent L24 to replace my JDM L20A. One has come up but it is an L24 form a 240K. Is there any disadvantage to not having one that came from a 240Z? I've read that the position of the bowl sump is different (K's have front bowl sumps, Z's rear). The set up I'm looking at also has an N42 head, which I don't think came stock with any 240K's.
