Ok i am running a kinda of a wild port and polished head on a LS(B18B) and 3 angle valve job also with i/h/e right now and i was told it is in need of extra fuel cuz its sucking in too much air cuz of the p&p and thats the reason why it is sluggish.
so my quetion is. is this true? and if it is can i just use a Adjustable Fuel Pressure Regulator? or do i need like a s-afc?

 

If the lack of fuel is the prob. get an AFPR and either s-afc or HONDATA.

Otherwise it could be another prob. ???

 

Well if you think of it, your head is now designed to flow large amounts of air through each engine revolution and the stock compression and cams can not move that much air. So now your motor is choking. Up the compression and get some cams to compliment your set-up!

 

how much over was the ports? cut are ypu runing a stock intake maifold and throttle body? maybe you should up grade your fuel system like pump, lines, rail, fpr,injectors to compensate for the increase of air volume.
