i know that the rod bolts are the weakest link on ls motors. will it withstand 5lb. of boost no problem, or should I be worrying about breakage. i also have 145k on the motor too but she runs very well in my opinion. i had a built 99 civic si and sold her and i cant stay away from boost. i am just a lil out of money to build an engine. have any of you had any experience with nippon pistons on ebay? how well do they hold up? because i think im going to try the xs power cheap turbo kits. i know if i decide to build my motor, i will want to change bearings, bolts and the whole 9 yards.
