I have an 01 busa and plan on some winter fun. I am pulling the motor, installing big bore (1397) and having my heads port/polished with new cams. Sending head/block out for completion, but i will break down and install. I consider myself knowledgable on motors, but never worked on a busa motor. Anyone doing/done the same thing and is it a hard job. Im just curious before I start. I have the break down book already. Ive done a lot of mods, but nothing this big yet. Any help/advice appreciated. Hoping to get about 220 hp when I am done. I already have the rite map for my PC.
