So i wanted to build a whole gsr motor from the ground up pretty much. I just got the block today, (bare block) anyone have suggestions on what size to bore it too without getting new sleeves? And could anyone provide a list of all sensors i will need. Thank you

 

bare block. man theres not much u can do with boring if u dnt want to sleeve but u could go .5 safely over bore i would recommend b16 pistons p30's
and a ls crank with ls rods for the best stroke

sensors
knock sens
water temp sensor
fan switch sensor
oil pressure sensor
well my memory stops there good luck on your build

 

Thank you.
