Hello together: I am a bloody beginner with many ideas in my head, unfortunately a lot will not be possible, I know that! but to my ‘project’: I have to buy a Jeep Wrangler of a medium old year of construction (ca. from 1998) and to completely disassemble this car with galvanized car and galvanized frame with 295′ he tires and sidepipes (at the B-pillar high) and threshold protection rougher, as well as solid front and rear bumpers rebuild! now my question: because the consumption of approx. 15-18 ltr at 4.0 seems a little high my question about the options: Conversions on gas? With nem 2.5 ‘er likes? or even what is my favorite at the moment: convert to a solid MB or BMW rows 6-cylinder diesel engine with approx. 2.5-3 ltr.? What do you see as useful, what is feasible, what is not? and how do you see my chances? I am grateful for any feedback! Exhaust could look like on this Suzi:
