Story time.
So Monday I finally received all the CP quotes from my Canadian sources. Everyone was willing to eat some cost but after tariffs and whatnot I was looking at $1800cad+. Insane. Wasn’t gonna pay that.
I wasn’t willing to accept this. I called CP directly. First guy I talked too was like “oh I’m not a Honda guy but let me transfer you to the guy who knows”
This is when I got connected with the guy. The guy who did all the things. We talked. At first he was like you don’t make no HP so wrist pin failure seems odd…then he paused and he goes..it’s an RPM problem isn’t it. All that on and off throttle, the downshifts, it is insane amount of stress on the rod/piston. Rod bolts and wrist pins.
Downshifts are hell for an engine. That piston just wants to leave the engine and the only things holding it back..wrist pin, rod bolts, then connecting rod.
Nothing to cushion or slow the piston. It is just on a mission to leave the stratosphere. Think about compression stroke. That’s a cushion. Power stroke, that’s pushing down which the crank is also pulling in a sense, intake stroke, again aided by the crank pulling, no real stress…then exhaust stroke. Nothing above the piston. It just wants to fly away. No resistance. That force increases exponentially with rpm. It is not linear. Far from. It is up to the rod bolts and wrist pin to stop that piston and completely change its direction. It wasn’t going down on its own of course.
He confirmed my use case was indeed extreme and he hooked me up with the 0.170” wrist pin, 9310 material. Apparently this is as gangster as it gets. Little bit of added weight but it is stronger than fuck which I need.
CP guy hooked me up with his buddy who has a shop and is a major dealer. He is Nippon North America which if you don’t know Nippon and Hastings make just about every piston ring for everything on earth. Every CP piston ships with Nippon piston rings. This dude supplies them.
This guy not only gave me a crazy discount on everything, but I paid $43 shipping, and I paid $22cad in fees and duties. Absolutely insane. He saved me over $400.
This guy assured me I would have 0 issues. He ships to Canada daily he told me and he knows what he’s doing.
Pistons were ordered Tuesday. They arrived today. Holy fuck. From California to Toronto in 2 days.
Side note, these pistons WITH the big pins are approx 5-7grams lighter per hole vs the Wiseco setup with their light pin.
Every single piston, every single pin, weighs exactly the same. Like, dead even. All of them.
That’s quality. That’s engineering. That’s what I paid for.
