OK Toyotaman, here's the skinny on why MCFA no longer uses their own engine to power their forklifts. First, I can't say that all of this is 100% true since the information was gathered from different sources, none of which have first hand knowledge of why the switch actually took place. MCFA had a problem with the Woodward LP system which is still a carbureted system, not fuel injected. The Nissan K engine is fuel injected with a drainable LP vaporizer, which comes with a 3 year warranty. The Woodward system is a JB converter with a massive electronic gadget attached to the back of it to control fuel. Also the 4G engine had some head cracking issues. Another reason is that the Mitsubishi arm that makes the engines has absolutely nothing to do with the Mitsu arm that makes the forklifts, so they are really independent of each other and can make their own decisions. And, the Nissan engine had proved more reliable over the years. Doosan also went away from the Mitsu engine and went to a Hyundai engine for the Tier 3 trucks. My opinion is that there has not been a better performing industrial forklift engine in the past 20 years than the Nissan H20 series, except for maybe, I hate to say the Toyota 4Y which is just as reliable. Probably a good choice on MCFA's part to switch.
