Custom headers and cam timing are next, if that doesn’t break the 6K barrier then intake revisions (plenum and throttle bodies) are probably next. For now I’m just going to drive it and enjoy the ride. Just had a great time at Japfest Goodwood followed by a track day there yesterday. Black Sunshine got a lot of attention and held its own on the track, what a great car to drive!

Car is running rough up to 2 to 2.5 k on cold start up.
I have been pointed in the direction of the o2 sensors.
Does anybody have a link with instructions on how to replace them?
Any advice welcome. :smw:
