Hey guys,
I've been offered a set of 40mm throttle bodies etc, without a manifold, to go onto my B16A. One thing i just can't find is the port sizes for a std intake manifold. The reason I wanted that info is the more commercially available kits seem to have either 45,48 or 50mm throttle bores. So I wonder if I take this kit will I be reducing airflow? Because what I planned was to get another manifold and cut it up then tig the new tb's to that. The company that made the tb's has a manifold adaptor plate for $650 I think, seems a bit steep to me.:thumbdwn: Anyone got any technical input on CFM calculations?
Thanks in advance boys,:thumbsup:
George.
