'well my thinking was if you have an S14, you have the T28...and swapping a s13 head would give you the high port flow, therefore giveing more hp than the stock s14...no?? : ), so therefor the S14/s13 would have more hp than the S13 or the S14 alone....right?ItzGenX wrote:It sounds like it wouldn't work any better. The internal bottom end of the two are basically the same. Swapping heads would be like swapping changing the s14 into a s13. If I were to do it, it would only be to get that ugly hump off the valve cover and to get it red. :ylsuper
