Performance
Hey guys, ive got a '93 Cummins(Old Old Body Style), and i am having trouble finding a good web site that sells performance upgrades and such for that year. Most start with the '94 and up. Do any of yall know any?

those old 12valve engines take some mechanical work to build good power. One thing the old VP44 pump can do over the new CP3 is you can dump LOADS of fuel into the cylinders. Then you have the timeing advance. it's almost an art when it comes to building power on the old engines, but when you dial that thing in you better hold on
