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!

Hi all just wondering what can you do to upgrade the standerd turbos?
i have heard that theres business that can convert them to ball bearing type with larger impellers.
If so where are they?
how much ?
and is there anything to upgrade in respect of this other then the ecu?
Do i have to change the jet size for the intake to get the most out of them?
And finally.......has any one had this done ? and what other upgrades would ye think i should do?
400 - 450 BHP is my aim with relibality beeing the main factor
thanks :bow:
