To begin the conversion, we needed to educate ourselves on what we were undertaking. We researched the vehicle and engine information of both the gas and diesel engines. We acquired an online manual for the original gas engine model of the 1994 Isuzu Trooper. We also found an excellent PDF file manual online 4JG2 diesel engine Trooper. The first few days were spent educating ourselves to understand the conversion process and the changes we would need to make to get the 4JG2 to fit in our Trooper.
The picture of the Trooper was taken after some work was already done.
