i have a 98 civic ex, i was thinking of puting either a gsr or type r, but after all decided to put in a B18b. Im thinking to put some high compression pistons in it when i get the engine.

i have looked around and saw some 76mm and 82mm, do i have to bore my cylindres if i go with these? will i see more power? where can some for a good price?

thanks

 

bump for u

 

82mm on stock sleeves is pushing it

 

just looking to throw pistons in or rework the whole motor

the head doesnt flow to great stock specialy in n/a form

you can drop pr3 pistons in there and have compresion similar to c5!

if you decide to get larger slugs you need to rework the chambers to acadate the larger head gasket and slugs!

throwing in larger pistons alone is a waste if you dont equaly upgrade all the other parts of the motor
