rebuild kits

where can i find an engine rebuild kit for the RB's? and where can i find the torque ratings for the bolts on the engine?

thanks

If you're going to rebuild it depends on what you want. Like for like? Or major upgrade?

well main goal is for around 300-325hp for starters. and since the engine will be out of the car i would just rather do the rebuild at that point than later on down the road.

which Engine in th RB series?

RB25 and RB20
