I hear that heat dissipation seems to be an issue in LSVTECs. The PR3 P30 and CTR pistons are all of 1.6L engines. Does this mean that they are not reliable with 1.8L displacements?
For the purpose of a daily driver, mild cams, and no need to rev past 8500, will all the pistons be good enough? I see that most people are using ITR pistons, I'd assume this is because they were designed for the 1.8 ltr displacement. Lifespan and reliability are a priority for me. But I'd like to go with the PR3 pistons.

 

Most people go with type r pistons because, they are type r so they must be good right? Actually I think it's the name, what sounds cooler, "they're Type R pistons" or "they're b16 pistons" They do have the friction coating on the skirts but it does come off over time. I'd go with cheaper PR3 pistons and a little bit more compression myself.
