Floating wrist pins?
If my rods are said to have Bushed Fit Pins - Floating, does that mean I need to buy a piston that has a floating wrist pin?
Which ones should I be looking at getting if that's the case. If I'm right, CTR pistons do not have floating wrist pins correct?

floating writs pin means the wrist pin is not pressed onto the rod or the piston, it is allowed to move freely in both. unlike oem, i'm not sure if it's pressed onto the rod or the piston though if somebody wants to chime in.
all oem combonations have pressed wrist pins.. floating being an aftermarket thing.. which is a very good idea.. most machine shops will tell you they are unable to remove pressed wrist pins without egg shelling the piston.. even with a jig..
its pretty difficulkt to press the pin out so its not really worth trying , on the upside though you dont have to buy expensive forged pistons to run a floating pin , you can get little teflon buttons made up that sit into the wrist pin and allow the pin to slide around. If the come out far enough they will just touch the bore and slide back in , its much better than circlips which can pop out and kill your engine.
So, if I get this right....
If I have a set of aftermarket forged rods that are brand new and I get a set of brand new CTR pistons, can I just run a floating wrist pin in the piston? And how would I do that?
