I'm thinking of rebuilding my old RB20DET block. I don't want to build it for mega kw, just stuff like balancing everything up. But I need at least 1 new piston - the original piston has a big chunk above the top ring land missing.
Also thought, though, about getting a bit more compression out of it. I've read somewhere about using 4AGZE(?) pistons when building a RB24. Is this correct, and will they simply 'bolt on' the the RB20 rods. The appropriate bore will give the increased C/R I'd be looking for, I guess. (I don't want a RB24 though)
Could use RB20DE pistons, but that engine runs 10.2 C/R. Any other way to increase C/R without major re-working of all the internals?
Thanks in advance.
