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!

Had my car up on some ramps and noticed that my Exhaust system was Made by Jasma.
Anyone heard of it?
Its a pair of big single pipes at the back.
Any idea of power increase from these?
