U need to change you pistons one rods to run v-tec on a b20b. If i change my pistons what type will i need not to run too much compression with v-tec...???
1) What sites have you been reading off of? - don't read them anymore
2) How much compression do you consider "too much?" - anything below 12.5 is good to go.

Use the compression calculator on cspeedracing.com to figure out your numbers, if it adds up to over 13:1 then you need to rethink your piston choice, or run a Cam2 mix.
