I actually found a set of Nissan Factory leads as new condition that I had off my car trying to chase a misfire but ended up being a Greddy emanage that was causing the problem, I never put them back on it . At a guess they did 20,000km .
I also have a full gearbox and brand new seal kit (Japan only) along with a spare gear set , it’s the ordinary Superturbo gearbox not the short ratio March r box , these are not cheap to buy as they are specifically for the March super turbo but message me if interested.
