yes and no for the same car, yes in the aspect that the acura rsx is equal to the honda integra,
but no that there not equivalents.
honda integra type r is better because:
JDM has larger throttle body and larger intake runners
JDM has higer compression, 11.5:1 (vs 11:1) pistons
JDM has different intake and exhaust cams
JDM has different fuel maps. We can remap our k20a2 ECU to run-JDM
JDM has a larger diameter Header
JDM has a larger diameter Exhaust (.25")
JDM Has SatNav system, we get CD
JDM has aluminum Lower suspension arms on Front
JDM Uses 22mm sway bars front and rear (we have 19mm)
JDM has Brembo Brakes (we have s2k brakes)
JDM has 17" light weight alloys
JDM has different speedo (to 180km\h and type r label) and Tacho (redline at 8400)
