Breaking for parts only. Mazda RX8, engine starts and revs however won’t idle, ECU has been tuned badly which I think is the issue, however the engine hasn’t been compression tested so will sell as is. All parts available, message for anything required, I can then create a separate listing to purchase via eBay rules for both our protections. If you need more information please contact me. Thank you This listing is for 1 10mm nut. If buy it now I will ship a single 10mm nut.
