This was something I dove heavily into. Almost bought an RBC and searched far and wide for an RSP. If you found an RBC ready to bolt in for a good deal, say $500 or so it may be worth it. I tried to find some dyno plots and saw that Kpower put together one in an E30. It mentioned only a 5 hp gain. Don't know if cams will make better use of the added CFM but it doesn't appear to be worth it unless you just had one kicking around.
