Default Re: Stroker Kit wouldn't help?

You do realize that the problem you encountered was more of a aerodynamic issue than an engine torque issue, right?
Have you looked at the size / shape of your ranger as opposed to the little car?
Problem solved. leave the engine alone

This x100. The Ranger's drag coefficent is in the neighborhood of 0.47-.0.49 depending on 2wd, 4wd, reg cab and supercab. These numbers are very high and are the primary reason any truck suffers in fuel economy. To put it more into perspective, a Prius has a drag coefficent of 0.25, a Corvette around 0.29. Your VW Touareg has a 0.38 drag coefficent.

To answer the original question regarding the availability of a stroker kit, yes, Morana has a 4.3L kit that IIRC gains 30HP at the crank and 30 ft lbs of torque.

I do not know any Ranger owner that has stroked either their SOHC or OHV engine. I also doubt there would be any increase in mpg with the kit installed, most likely a decrease.

My advice would be to do a V8 conversion as you'll be money ahead compared to the cost of stroking a 4.0L V6 plus the intake and exhaust mods to maximize performance gain.

What I can tell you from rebuilding/ modifying my 4.0L OHV top end, intake and exhaust was about a 32HP gain at the rear wheels and an increase of 1.5mpg. Cost was approx $1750 for parts. Bottom end remained stock. The rebuild was out of necessity rather than performance, the gains in HP and mileage were a bonus.

What we are saying is that it makes absolutely no sense to spend upwards of $10K to lower & modify a 4.0L Ranger to get 25 MPG. Their are no cost effective way to make these trucks more fuel efficient. If you want fuel economy in a Ranger, you need to trade to a Ranger FEL package(2wd, Reg Cab, 2.3L, 5spd, 3.73:1), period. You will not save any money, in the long haul modifying your current truck to get better mileage. I'm averaging about 22 IMPG at the moment with my Sport, Dad's 2010 FEL is getting low 30's. I don't spend every waking moment whining about my fuel mileage, I bought this truck expecting to get the mileage I'm getting. The absolute best fuel mileage set-up these trucks ever had hasn't been offered on our shore since 1988, the diesel powered models got upwards of 40 IMPG.
