rite now i'd just bought an B18B blocks. But i'd already purchased an CTR pistons....mostly people advise me on getting an P30's which will give me more CR on my engine....

and if i'm still stick to use an CTR pistons, how can i reduce or diminished knocking issue? ...........

 

anyboy?

 

mmm, use a thicker HG; enlarge the combustion chamber.

 

Proper fuel & ignition tuning is the key

 

Fly cut the valve releifs for more clearance to play with cam timing. Youll lose a tiny bit of static compression, but youll be able to play with your cam timing more, enabling you to shift dynamic compression around and help ward off knock.
