Yeah, Preston of ProjectZen is a dude, have a chat and I'm sure he will sort you out with what you want!
Dino, I'm sitting here with a worn connecting rod from my old JP RS12 motor and a spare rod for my d5r motor, dimensionally they look the same and my vernier verifies this. are they interchangeable?
These cnc sts rods look like jewelry and it weighs less than my old JP rod, I guess if it fits it would be a little hop-up for my JP motor.
Cheers
