powerstroke V8 to V4

Ok, I am new here. I may be one of the few people that prefer fuel economy over horsepower, but here is my question. I would like to disconnect the injectors and the valves on every other cylinder in my 2000 7.3. This would make the engine half the size. My method is crude, but this is similar to the variable displacement engine that chevy is using in there gas burner.

Welcome to the site, but you would be better off getting a tuner an exhaust and an intake. It wouldnt even run if you did that stuff and if it did it would run absolutly horrible.

I can get 23 on the highway and i have 450 hp, IMO, I would go by a YUGO before I destroyed that 7.3.

I want to meet the guy that gets 20+ mpg. I have never gotten over 16 mpg. I have a performance programmer, but it did not change fuel economy. I average 12 mpg in the summer mixed driving and under 10 in the winter. It has 140,000 miles and has never worked a day in its life. It is a 2wd. I bought it with 125,000 miles. It was driven by a female tax accountant before I got it. I would gladly take any advice.

The engine wouldn't be balanced, dont do that! Like everyone else says, exhaust, intake, chip, and one extra to keep you safe if you go with a custom tune... Gauges!

yea. just go with the mods and you will be much better off.

Oh and that system where it stops using valves to get better milage is BS. My 7.3 gets better milage stock than my dads 2007 tahoe.

one question though, why do you want to do that to your 7.3? If all you wants economy? just a thought.
