Well i was considering doing ls vtec.Was gonna do it right with p30 pistons,arp rod bolts then stock bottom end.I was wondering if it is absolutly nessacary too hone the walls when doing this over.My engine is fairly new and im not sure if i will need too do it?

 

any change in pistons and rings require honing so that the rings
seat properly.. ps
do not forget the breaking period....

 

thank you.I will probably bore out the pistons then if i have too rip out the block from the car.What piston size makes 2.0? 84mm?
