So last night my car shat its pants on the m25 had it recovered and taken home. The engine had covered 163000 in its life so I'm just going to replace the engine with another agu. While ive been looking into another agu engine ive been reading that some people are saying they have forged pistons and crank is this true as I was thinking of changing the pistons and rods while the engine is out ? any help would great. thanks jake.
