Yes slowing down the engine means less power. It was geared the way it was for a number of reasons. You just need to spend more time in third to compensate. Not only are you making less power but you are increasing stress on the engine. Unlike a real truck engine it really is not designed to be continuously lugged. The increased torque requirement means higher stress and cylinder pressures which increase heat and NOx emissions. I would invest in the later-turbo diesel engine for the increased power and strength. The pistons and crank are not the only differences.

Hi Volks!! Took my first trip with the air cooled tranny in Velma and loving the rpm change at 60-65mph. With a slight tail wind we squeezed out approximately 31.4 mpg on mostly river grade!! Now the downer, now we need more power!! The hills are slow going and a head wind we can maintain. I found a turbo kit for about$ 500.00 which includes turbo,down pipe,intake and exhaust manifolds but would have to get a turbo vanny intake manifold that I've seen for$ 60.00. The problem would be finding the forged crank and installing piston oilers. Im thinking I could do a full rebuild into a turbo motor for about the same $ as a used AAZ motor! Will a 1z ahu tdi head match up to my 1.6 ?? Thinking more efficient being direct injected and better flow from head and camshaft profile?? Decisions decisions!! Thanks for any info!! Velma 82diesel 1.6 na westy |
