when i put on the b20 head with the way bigger intake ports, the powerband went from starting 3.5-4k to 5-5.5k
but it seems like it goes better up there. sucks waiting to get there with long gears

 

hahahaha lol

 

ok.. so other then the slowness. it idles fine, revs smoothly, sounds good? if this is all the case just go ahead and turbo the biatch.

 

the car idles very normal. at 500-600rpm, heads not leaking. reve smoothly and sounds smooth. i'll turbo it soon. but i really want to get the head fixed first. my situation is like random strike but worst.. power kicks in at 4300 rpm. and when i try increasing fuel pressure to 40,45, and 50 psi and the car just gussle gass but is still pretty slow. trying to fine tune this sucker is a big hassle. the port job seems fine..
any other suggestions??

 

i have a complete b18 head minus cams and throttle body i can sell you if you're convinced that's the problem
