I am looking at options on where I want to go. I was doing research since I pulled my engine. I am searching ic and conversions to see what is going to be my best bang for the $$$. Anyhow I came across this for the dmax and I do see the stock 04 on up is 310 @ 3000 hp 590 @ 1600 turque If this is true than I should be able to get my 6.5 to a run like/with a stock 06 dmax if I am right. What do you think?:confused:
1993-up GM 6.5L Turbo V8
The GM 6.5L was an evolution of the 6.2L. With a slightly increased bore and stroke, it was larger by a few cubes but it had a stronger bottom end, better heads and, best of all, turbocharging. Like the 6.2, it was used in the half-tons on up, but the applications were somewhat more limited than the 6.2L had been. There were 155 hp NA engines available for certain applications, the Humvee for example, but they are uncommon in general use. The turbo engines cranked out an honest 190 hp and 385 lbs-ft in most applications. The very first year used a mechanical DB-2 pump like the 6.2L, but the troublesome weak link has been the first generation DS-4 injection system that followed. It combined a mechanical pump with electronic controls and was a bit cranky at first. The fixes are in place to make it work well nowadays. Being a somewhat stronger platform, the 6.5 is capable of up to 300 reliable hp and about 550 lbs-ft., but you have to spend some fairly serious money (a special injection pump) to get it past about 250 hp. It desperately needs intercooling with the boost needed to make 300 hp. This engine remains in production, with some limited applications in the commercial GM truck lines and with the AM General military Humvee and the civilian H-1 Hummer.
