OK, getting pissed off now. I just found that my 599 1993 6.5 NA out of a van with 52,000 miles that ran awsome has a cracked main web on one of the main bosses, it goes from the outer hole with the smaller bolt towards the cylinder wall, looks like an inch or so. Then I pulled down my other...

Im in the process of doing my 6.2 with a ATS turbo swap into my 1990 K5 blazer. The question I had was do I run a CDR valve between the turbo or just a pipe between the oil filler neck and the intake pre turbo. The factory setup for the ATS is directily to the turbo with no cdr valve.

My wifes 1997 GMC k2500 HD with the 6.5 gets lousy mileage, even with the 285/75/16 tires on it. Rpm's are at 1850 at 55 mph and over 2000 at 62. Truck seems to get great milage at 50 mph, but a 60 and above it falls of really bad, like 3-4 mpg. The truck has 4.11 gears now, can those be swapped...

Ok, here we go, Im getting ready for the 6.5 DB2 swap into my 91 V3500 crewcab (old body style). Truck has a 350 gasser now but is getting a ATS turboed 6.5 in its place. A few questions. First of all, can I use the factory in fuel tank electric fuel pumps, for the gas TBI the tech manual says...

OK, it cold here now and my 1984 gmc with 6.2 starts after 17 seconds of manual glow plug time. starts fine but misses. the truck has true dual exhaust and out the pass side it puffs LOTS of blue smoke, but not out drivers side. The engine also sounds like it is backfiring into the intake with...

Ok guys, I sold my dually crew cab and bought a 1991 K30 crew cab single wheel with the 4l80e and 205 t-case. I still has the factory gutless 350 gas engine with TBI injection. NOW my goal is to swap my fresh 6.5 diesel with an ats turbo setup into it. What kind of control do I use for the...

So, is what I got is a '99 humvee 6.5 that I just removed the heads on it because of the oddball intake angles. I am getting a very low miles 1992 gmc fed ex van 6.2, it has 30,000 on rebuild. Will the heads work on the 6.5 or do I have to change out injector lines, will 6.5 turbo injectors fit...
