Diesel Swap?

Searching around the foreign nissan sites i found out the navara (nissans UK version of the frontier) comes with a diesel engine.

Though it might make for an interesting swap for more down low torque (300 at 2000 RPMs!!) and almost doubled gas mileage (24 city/39 highway, plus diesel is usually cheaper than regular gas)

seems like it would bolt right into the X, I believe you would need the diesel's transmission as well, as the gear ratios appear to be different.

check out the engine specs at:

and the nissan site:

no clue where you would get one of those engines though, would probably be a PITA to find in the US, or get shipped over here.

Consider this, 2000 RPMs is likely near redline for the motor. You would need to replave the transmisiontoo, as it would be gear all wrong, and are you sure those fuel numbers were in MPG and not KPL?

check the link, the mileage is in MPG

The actual experiment, just for the zombies to reference.

Basically take 50 gallons of vegetable oil in an old hot water heater and add methanol along with some KOH. Wait. Glycerol/water/excess methanol will separate as a lower layer the methyl esters of the fatty acid chains (biodiesel) will float as a separate upper layer. Drain lower layer. Do some simple tests for pH, etc. and you are good to go.

We do this experiment with undergraduates to illustrate the process on a smaller (beaker - separatory funnel) scale.

Biodiesel does not require more energy to create than it produces. Even the USDA EIA website, which is very conservative, states that biodiesel has a significantly positive energy return on energy invested. It may not be a perfect fuel for other reasons (like cold weather performance and stability), but EROEI is not an issue.

because the average American STILL thinks that diesel vehicles means black smoke and expensive prices... which now only the price of diesel fuel is expensive...for no reason at all

options for diesel vehicles are slim and pricey. the German imports like VW, Audi, Merc make diesels and so do our US truck companies(Ford, GMC, blah blah)

here's a list, http://www.dieselforum.org/uses/cars-trucks-suvs/diesel-vehicles-currently-available-in-us

Gasoline engines are more fun to drive than diesel, because you get real power over twice the rpm range. So, it pulls longer before needing to shift. Diesel engines will always have better fuel economy, durability, ease of repair, and the fuel is easier to make than gasoline. Diesel engines are just better than gasoline, but they have too few rpms of good power, and the exhaust notes are not half as sexy as gas engines. So, my wallet, and my belief that simpler is better, make me really want a diesel, but my heart makes me really really want a VQ40. So, I want a diesel, but I don't want want a diesel, because the VQ40 is just too damn good.
