The only truck that was faster was the Elcamino SS, but I don't consider the Elcamino a pickup. The Mitsubishi 2.3 was an amazing little diesel and it was the only one of the small diesels that was built to be turbocharged. All the mini diesels were converted from natural aspiration to turbochargers. This really reeked havoc on the rods, heads, pistons, valves etc. Here are some number to think about. This is a list of all the small diesel sold in the states during the 80's. So of the info is missing but I have done the best I could. Most of this info came from magazines from the 80's and the MPG's and 0-60 times were the observed times by the magazine like Fourwheeler. In my opinion the 4d55/4d56t was light years ahead of all the other diesels.
