Dunno how much I agree with there not being much difference between sohc and twin cam vtec but good on you for choosing to DIY build. :thumbsup:
Should check out grifty's MA3 build thread, he's got a D16 frank with JRSC supercharger. I think it's going to be pretty damn good. When it comes to sohc engines I honestly think building for boost is the way to get power as they don't respond well to NA modifications.
Best of luck for the build regardless.
