    should i sleeve my ls block to run 18psi? Or should I just clean it up, hone, pistons/rods, itr water pump & oil pump? Asking because i do not plan on running more than 18psi max with a 60trim turbo using a stock b16 head.

    should i just use the stock sleeves? The machine shop told me that the spec sleeves he uses can bullet proof the block and handle up to 55psi. I will be using a full-race kit that made 420whp on 9.0:1 compression ls/vtec with stock gs-r head on pump gas @ 13psi. Asking because it will save me $1000 at the machine shop. running stock bore as well, 81.5mm.
