I need some opinions from you guys, I'm trying to decide which motor to work with NA. I've been debating between the b18c and the c5 lately, more so the R because of the lsd. I havent really looked into all the big differences between the two, i know that im going to have to swap the head regardless, anyway, any feedback would be great. oh yeah, no LS-vtecs please, i want to be able to rev it out more than twice before i have to call it a night.

 

Why do you "have to swap the head?"

 

b18c5....but do what you want...
