well, when I was still working at a Honda dealer, I saw some s2ks thats needed their TCT to be replaced. The cause of the TCT to wear out faster is indeed depends on the way u drive the car (especially when you gun the car from standing start).

Toda got a beefier TCT for the S2k now, and it does look really good too

If I were you, might as well change to new guides and the timing chain to Toda unit as well XD
