I've heard both good and bad about using total seal or gapless rings. I'm going to have to read more into that on why. That and looking to see if someone or some have bored the motors over .40 trying to get 3.2L of displacement out of the VG. I want to try and get as much displacement as possible so that I don't have to run the turbo's up near there limit all the time to get that power range I'm looking for.
