Hey folks. I'm sorta bringing up a B18c4 vs B18c debate again. what I'm trying to find out is: for a high comp build what one is best to go for. Before people start screaming use the search i have done so on this and other forums. The closest i got to was on another forum where a guy had a B18c4 and with a build cost of £2300 managed 203bhp using OEM parts from ITR etc.. Now that £2300 could be spent on a full JDM B18C swap with the 197bhp. Going this route would save a bit of engine building. but if building a more aggressive head using aftermarket manufactures would it be more efficient to use the the B18c4 with its lower cost to pick up. Or buy a b18c and install the aftermarket head components further down the line when money permits. Would the b18c always produce better results or would it cine to a point where it would start to balance out?
