From memory doesn't the jdm 4efe rev higher hence where the extra power is made. Uk's are 6250rpm from memory and jdm's are 6850rpm Obviously this is linked with the ecu, and iirc the injectors too. Some models of the Glanza s also came with distributorless ignition.
Well the black wheels had a slow puncture with got worse and ruined the tire, so I had to fit my old wheels back on, so after a quick refurb thy returned to the car. Now in new marmite colour flavour! I foresee a large amount of haters! Lol
