built head, eprom, dsmlink

[Shane@DBPerformance]

Which one makes more power though? Take a look at the port size on an Evo head, it makes 2G stuff look big. And those heads make killer power compared to DSMs. I have always had good results with 2G heads on cars from 16Gs to GT35Rs. The 2G intake manifold and throttle body do suck. I have one customer with a stock 2G head(with 272 cams) on 2.4l bottom end and 61mm turbo. It makes a tad over 400 DD awhp at 19psi on pump gas.

Well tell me if I'm dumb but I was planning on doing a 6bolt bottom end down the line when/if my 7bolt walks and I thought i'd just be easier if I started out with the 6bolt head. Plus I figured that the 6bolt and 7bolt heads are the same except the 6bolt flows more. Am I missing something???

It might flow more but like Shane said, look at the Evo head as an example. The least restriction(flow) is not necessarily the key point. You need velocity to get the air/fuel charge into the combustion chamber.

Get to the point of a huge turbo and maybe the 1g head will be better? I cant say for sure because I have never researched it.

I have a compleat evo III head
bigger stock cams ,heaver springs,flows the best of the heads
