well...the header is a big part of s/c applications...right now youve got a bottleneck - but not enough to have that much effect, Id think.
The blower for the 18b is kinda small imo. A crv crank pulley would change the boost to 10-11 (some say 12)psi...and its a lot cheaper than a jr piece. (Youd need a belt thats 865mm then)
