Long story short retimed up no compression on any cylinders. So what are best options remove head approx 56k on engine replace engine. Or remove rear subframe and go from there. Just passed MOT after being off road due to covid. Time could be an issue. Don't want to break or though this could be an option. Really fancy a Nissan 350z. Any thoughts thinking best option is to get a hopefully HFF green rusty/accident damaged and change engine?
