DOH!!

gutted for ya mate. did it happen during mapping?
maybe a 2.5 forged lump, bigger turbo is in order to brighten you up.
good luck

 

Sorry to hear that of course. Performance testing always carries a risk, and if the journal's time is up, that's that. Big end knock always seems to come as a surprise with these engines, like they just won't put up with any clearance issues and just roll over suddenly.
