I've been thinking about doing this for a while, now it looks like I can get a set of A1 pistons from a friend here at school who is replacing the motor and tranny in his teg. One cylinder is running no compression, could there be a problem with the piston in that one? The others are all at 180-185. Anyway, can I just take mine out and put the new ones in (with new rings of course)? Will I need to do any balancing of the crank or modification of the pistons/rods? How will it affect my redline? I read that the A1 rods are stronger than the A6 rods, which are the weak point in the engine.
