just a quick question about pistons for a b20vtec setup.. I did search and all im wondering is if the stock pistons would be fine? i am aware of the valve relief for vtec but is it necessary to change the pistons?

 

if you want more compression change them out

 

I'm not sure what you're asking for...but if you would like to make a bit more power you should look into sleeving your block and upgrading your pistons to higher compression. The b20 sleeves are weak and i believe the weakest of all bseries motors.

FYI the oem pistons on the usdm b20Z are a bit higher compression versus the jdm b20b. Either way you can always slap a vtec head on but knw that depending on how high (rpm) you take it up ...you increase the chances of busting ur sleeves...faster....

hope that helps homie
