WISECO PISTONS

[giopapy]

I would like to put on my Busa 4 new WISECO pistons the comp.ratio will grow to 13:1, but the displacement is as standard 1298cc because the size of piston is 81mm I would like to know if is it possible to leave the rest of the engine as stock or do I have to change cams or anything else???
Is it better to put the 84 mm size pistons ( the price is the same ) but then there will be much work and money on cylinders.
How many HP should I gain???

P.S. Sorry for my eng but I'm from ITA

Gio, check the post in the 1/4 mi section titled "big bore kits". Just keep in mind you can raise your hp by compression increase, but you reduce reliability and ridability. Also, remeber the Busa has issues w/ compression stock; starter and cam chain. I would consider other means of perfomance. just my whats left in my pocket after owning a Busa .02 cents
