iv searched but only can find all motor stuff for a b20vtec build
im about to go buy some pistons and rods and wondering if i should buy for a gsr block or a b20 block right now i got a stock b20vtec turbo and i want more power if i was to build the b20 block i know people say the sleeves are weak and its all in the tune but would block guarding the b20 do anything?and what crank would people use? im looking for 400+whp what would people do?

 

i'd put the b20 crank in the b18c block... and don't use a blockguard... the ls and b20 crank are both the same, both 89mm cranks... or just boost the gsr block.... but for 400+ i wouldn't trust the b20 block without sleeves
