MAJOR THREAD BUMP
i am in the quest of removing my HKS GTRS's finally - after deliberating for a loooong time, so i skimmed thru this thread which really provides some great reading & insight from others. they are just awful on a 2.6 to put it simple - i had enough!!!
paul - u are right that post no.7 by Gav sums it up as u mentioned on the UK forum.
with my 2.6, it is a built engine with tomei poncams (260's / 9.15mm lift) but i am a little undecided whether i would be happy with -9s (330rwkw) or -5s (360rwkw+). i'd like to know if anyone can share an overlay of these 2 snails, possibly? from my own due diligence, we are only talking a difference ~ 500rpm in low end boost response...
