i know this has been pretty much covered but i got an 89 ls integra w/ a jdm b16a1 swap and i have a gsr94. i want to put the gsr head on the ls. i plan on haveing it professionally done. how much more horsepower should i see when this is done. how much will i be spendinng and do you guys think it will be worth it? and should i upgrade the ls tranny to a gsr, would that be better?
