normally the blue backed dials are from mid 92 models to 89. i have grey with the green lights, mines a late 92 model.
Dr Drift ECU... not too sure what he charges these days for a swap over... about $250ish if u want it tuned on the dyno i have no idea... he just chipped mine to a map which should suit my mods so i didnt even have to test it on a dyno it just ran bloody well!
