I am finally getting around to building a motor for my 240z. I have core motor 2.4 with an e88 head, I also have an e31 head lying around. I have been out of the z circles for a while now running my ita acura and spec e30. I am looking to build a good reliable motor that makes decent power. This wont be a full on build but more of a fun car that I will do an IT race with occasionaly and maybe a couple of vintage events. Cost is certainly a factor, not sure if I will go .040 over or not. curious what guys are doing these days.......
