so you dont think all the parts it comes with are worth the price? all the parts are brand new, in the box JDM...pistons are JDM integra TYPE R...the main reason i liked the setup is because it's all brand new from an integra TYPE R...and for the price, and all the parts it comes with, you can't beat it...i thought about a used B16 head, but this setup seems like it would yield alot more power...and i only want to have to do this once...im building this car from the ground up...HID jdm front and rear end, jdm rear hatch, ITR wing, ITR wheels, full JDM ITR interior (guages, seats, carpet, center console, boot, knob), ITR power mirrors, possibly 5 lug conversion...i basically want my own TYPE R...and what kind of gas do u think i'd have to run with jdm ITR pistons and rods? if premium will work, that's fine because i have my accord as the daily driver so i wouldn't use this one enough for gas to be big factor...although like anybody else, i'd like to use regular if i can
