For that purpose, a 6.2 might work. Or as noted, try to find a crate 6.5, for the most part, that is a bored and slightly stroked 6.2. If you do try to turbo either one, try to cut the compression from the stock 22-1 or there abouts, down to 18-1, makes for a longer lasting motor, and you will not blow the thing up as easy with too much boost. If properly setup, a 6.5 should net you 18-20 depedning upon driving habits etc, with a lot more get up and go. The 6.5 does have like the 6.2, or the IHC IDI6.9/7.3 power off the line vs the newer turbos, seem to have a bit of lag, including my dmax. But once the lag is gone, they scream past these motors.
As noted, yeah cheap to work on. Injectors for $50-75 each, vs 400 in rebuilt form per on my dmax! one can get a set of hi pops for a 6.5 for less than a single injector for my dmax.
Have fun with the project.
