I'm planning to get a b18c on my ej6 next 2 months maybe. I also want to build it before i drop in the motor. I was looking at Jun's product stage 2 cam set. piston. Bore 81.0(not sure what this means)what is bore? 81mm is the piston size i think whats the stock b18c piston size? if i put this in a b18c do i have to make the sleeves bigger? or port it or something like that. IF i get this piston kit do i also need to get the connecting rod also?
 
you need to be more specific on the specs of the parts your looking at to get any real good advice on them,
81.0 is stock bore size, the pistons are probably made for a race engine and would prob give a crazy compression ratio?, if you were to use those cams and pistons you would also need aftermarket management, also springs retainers pulleys etc
 
jun is overpriced, you could probably get someting better for less money, ross, wiseco, supertech all make great pistons, you should go to 81.25 bore size to ensure good sealing, also pick up a set of forged eagle rods, new bearings and a new headgasket. establish a power goal and budget and we can help you better. also what type of fuel will you be using and what type of engine management for tuning?
