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!

i've no running issues with my NA recently until today...
... all 3 times i've started it from cold today i've had rough, coughing, spluttering, misfiring for a few minutes
no fault codes, running perfect once warmed up..
any suggestions? has had a full service a few months ago (plugs fuel air oil etc)
we've had a lot of rain recently but rains never been an issue before, and its been in 3 very different places today.
idle is perfect all the time, was only once i opened the throttle.
