Hi guys, whilst my mini is have some welding done, I thought I would grap the chance to upgrade the engine, so what is worth doing on the busa? I have just bought a ported and polished head, with, reground cams to add performance.
Is it worth adding bigger valves, or save that for turbo or bigger BHP?
I will buy a clutch kit with anti ramping ring, and stronger springs.
Is it worth swapping the counter balance shaft for a alloy one to reduce flywheel weight, and make engine more responsive?
Also I am looking for some adjustable cam sprockets for the cams, as it came with non. may be interested in other performance parts for the busa.
