Hey guys, looking to build a b20 vtec, and have started collecting parts for the swap.
After a bit of research ive heard of notching the pistons for use.
My question here is... well what exactly does this mean (forgive my noobness, gotta start somewhere) and which pistons would be best to use (can I use b16a pistons or would b20 standard ones be better (looking to stay on a tight budget))
For reference, it will be a b16 head with b20b8 bottom end

also, any recommendations/experience regarding workshops around Sydney area?

Thanks in advance
