Also interested in knowing what's available out there for uprating the BKD clutch. I have a Shark Remap to 182 bhp, last time I checked, but if my turbo ever went I would go hybrid to replace it.
JP, if you are aiming for 400 Nm you may struggle to get something that low with a turbo capable of 260 bhp.
My OEM garrett turbo (with remap) has been dishing out ~410Nm for the last 11,000 miles.
Interesting enough also, my standard clutch hasn't missed a beat or shown any signs of slipping, ever.
