Non. They are 2 completely different motors other than that they are both 3.8 litre engines.

The older 3.8 already has decent pistons and rods from the factory with a boost friendly 8.5:1 CR ratio. The older motors love boost as they came from the factory.

Contact Powerbond and see if they still do a balancers to suit the 3800V6 with double belt drive. They used to do a conversion balancer but this file is from 2017.
