TTS Performance are offering a big bore kit (998) and claim a 15% power increase. Anyone got one of these installed? What about problems, overheating, big end stress, valve to piston clearance etc.

I'm thinking about hi comp je but this may be a better way to go.

2 cm3 is considered big?

Those ARE JE high comp pistons. It's a 98mm bore, which is stock.
