I have a R33gtst and the engine was rebuilt all std but with forget acl pistons. I have upgraded alot of things like injectors, ecu, highflow turbo etc.... And the car has a very SAFE tune of 265.5kw because my tuner doesn't know how much the engine will take before it breaks (Because he didn't rebuild the engine). Will just replacing the rod bolts be a good idea and push more power through? Or would it be much better to just enjoy the current power and get a full rebuild later down the track? Can the rod bolts be changed while the engine is still in the car by just dropping the sump?
