its probly already been answered but i searched for it and couldnt find it so i got a b18c1 block and i want to bore the thing out but i dont feel like having the pistons on this thing running on the coolant ports lol. anyone know a SAFE boring limit i was hoping to do .020 over. but if i can go more then i will as long as i know im not gonna pop my block....
 
well my goals numbers wise isnt really there im just hoping to build a sick na engine but i do have hopes for a turbo later but i do plan out boring the engine either way. i was planning on doing .020 over but i was wondering if someone would say to go more cuz the last thing i wanna do is spend all that money on boring to only find out i could have gone more. yea ill do 20 over. what im hoping to do depending on the money is bore and sleeve the block. i have the engine totally dissassembled so i wanna build this thing to holy hell before i throw it in my del sol and get too lazy to take it back out lol.
Let me ask you this, what are your goals for this build?
 
Stock sleeve NA = 1mm over
Stock sleeve boost = .5mm over

Resleeved boost = 5mm over
