new piston and sleeve

[Rs4 drift]

i need to get a new piston and sleeve for my hpi rs4 do i also need a new wrist pin and connecting rod to?

I've heard most of the experts on here say that you should replace the wrist pin and conrod when replacing the sleeve and piston. Not sure if that's across the board for all mills or not.

It's usually recommended, but I have done several with just a piston and sleeve and have been lucky enough to not have problems.

The con rod is the most common point of failure when an engine grenades so if you can its a good idea but plenty of people have gotten lucky without

replace the con rod! You can't be too careful and since the con rod takes 90% of the abuse, it's a good idea to replace it. JMO.
