its standard, it came with the engine, my friend found the half cut at the junkyard in japan in 2008 so he brought it back to sabah and sold it to me for 5k, its a 4agze HKS twin charger with HKS ECU, but something not rite about the ECU, i notice the chip(the main processor) were replace, now my engine idle are not steady, the lowest is 700 rpm and the highest is 1100 rpm, my friend said its normal for high rev engine to have unsteady engine idle, but its doesnt make sense at all, i check everything about the engine, except for the turbo(HKS), everything seem normal, even the supercharger pulley are normal, i also check the original dashboard and found nothing special install in it like a high rev tachometer gauge, boost/turbo gauge, oil perssure gauge or anything, this is 1 thing i cannot figure it out, or maybe the chip???....
p/s how do it post a picture in here....hehe(im new by the way)
