Hi and welcome to mightyram. A survivor truck with one owner! And it looks like it's in pretty good shape too. The engine should be a 4G52 2.0. We have a thread for all new-to-D50/MM truck owners on what to get onto first - http://www.mightyram50.net/vbulletin...and-do-it-ASAP. I like the 4G52 engine - to me it's like the unsung hero of Astron engines. If it's a 4 speed you have the option of swapping a 5 speed from a later 5G54 2.6 optioned truck. These trucks are a good flexible platform to tinker with as a lot of parts from other models and generations of Mitsubishis with interchange. Keep us posted!
