Maybe start by comparing the initial cost and availability of each engine on your part of the planet. 4BT's are generally pricey, especially when found on the internet. Most poor running 4BT's cost as much as or more than a good running 6BT. A lot of the 4BT's develop head gasket issues around 200K miles in stock tuned condition. It's your choice.
