S intake manifold differences
I'm planning a build for a JRSC on a H22, I know this is the N/A forum but figured you guys would know more about this and I did search. I'll be using only the lower part since the JRSC adapts to the lower part. Is the S different then the USDM in the runners? larger TB? any reason to upgrade from a stock IM?
