I can list out the changes, not particularly ordered but this is the gist:
Existing cylinders machined out of the engine cases and replaced with new, 100mm diameter Nikasil cylinders, which close the (previously open) deck. This boosts capacity to 3.7 litres from the 3.4, and 3.9 from the 3.6
Carillo rods, custom pistons
Custom ITB's with Porsche turbo injectors (as they're relatively inexpensive and we know they support our target power), dynamic ram pipes
I can list out the changes, not particularly ordered but this is the gist:
I like the idea of angry cams, 8,500 rpm and ITB's, should be a nice balance to the somewhat vocal exhaust. RIP getting into quiet track days.
