The 2JZ is almost as prevalent in engine swaps as LS engines. If I were to choose an inline 6 for a foxbody, I would go with a Jaguar AJ6(4.0l all aluminum, 250HP NA), a Chevrolet Vortech 4200(4.2l all aluminum, 280HP NA), or a Ford BF engine from an Australian Falcon(4.0L Iron block, aluminum head, 350HP Turbo)...the choice boiling down to whether I wanted a carb(AJ6s are one of the few DOHC I6s with a distributor, so running a carb would be easy), The most stock NA power(Vortech 4200 "Atlas" engine makes 280HP NA from the factory) or the highest power potential(The Falcon Xr6 BF turbo engine makes 350HP+ stock and are built to hit as much as 1500HP from time to time, their nickname in development for the engine was "The Gull" because they knew it would crap all over every competitor). I like the 2JZ engine...but there are so many other alternatives that I couldn't bring myself to use such a common swap engine.
