wonder was there a turbo timer on it or an alarm with turbo timer built in and they were taken off b4 you got it and wiring is dodgy, dont suppose by any chance if you let off hand brake it effects the ignition lights?
My type-R went to Mark Murphy Motors for inspection today. James - one of Mark's mechanics said it might be one of the relays sticked under the dash, as the turbo solenoid was clicking too (while the ignition off )
