Nope, nobody is saying go R32, honestly that has it's own set of problems (breaking parts! instead of breaking traction).
Just making sure your expectations are set correctly, but honestly, you dont NEED 550 whp. You can make that GTI faster than your CBR600 withOUT building the motor. You can have a lot of fun with just a headgasket spacer motor. These motors are so tough it's ridiculous. I have over 80,000 boosted miles on my headgasket spacer'd motor and the problems I am running into now are with the chassis, suspension, bushings, etc. The motor? Perfect.
