So I know that Edo hosted a thread covering some info on the RDX crankshaft a little bit ago, and many people have tried to bring it back from the dead because it was of such interest.
From the other thread:
"The RDX uses a forged-steel crankshaft with a long 99mm stroke. To reduce friction and improve durability, the crankshaft journals are micropolished. Special forged connecting rods are engineered for the engine's high power output. The RDX has special alloy pistons with thick crowns and super hard Ni-P plating in the piston ring grooves to provide a long-wearing surface with extra heat resistance. A high-capacity oil pump supplies oil jets directed at the underside of the piston crowns to help dissipate heat." - Source
B/S - 86mm x 99mm
Rod Journal - 0.780"
Wt. ~37 lbs (2 lbs less than TSX Crank)
Oil Pump - 15100 RWC A02
"All journal dimensions same, all rod bearing part numbers same for both TSX & RDX. TSX uses PRB mains, RDX uses RAA mains."
*The above was summarized from the other thread for future readers
My question is if the RDX's crank is stronger and lighter than the TSX's, would it be safe to say that all you would need to do in order to use it is swap the cranks...or is the above write up telling me that this form of a swap would req. "special forged connecting rods", "alloy pistons with thick crowns and super hard Ni-P plating in the piston ring grooves", and the "high-capacity oil pump" with the oil squirters we already see in some K-series blocks to make it a smart, functional improvement.
And if so, do you believe it is worth while on an all motor build. The fact of the matter is I will most likely be getting custom pistons, and rods anyway for my build and I just thought...why not the RDX crank. If there is more I should know, please enlighten me.
PS - A link to a lot of RDX overview information from another forum
