most fuel efficent engine swap?!?!?
so im bored at work today daydreaming and ive been thing about this.
i have a 91 4X4 standard cab with the 22RE... and well, as you all know its pretty guttless. but i like it, it gives it charachter becuase it can still do anything.
but since ive been on this site for the last 2 months ive read alot about the different motor swaps people do.
but i started thinking has anyone swapped in a newer corolla or camary engine?
they have to be pretty comperable horsepower wise to the old 22RE and get alot better gas milage...
i also have a 2002 ford ranger and the thing gets 30+ mpg at times depending on how im driving, ive not at least 28... it sucks though becuase its a ford and has no charachter at all
just figured i'd throw this one out there to hear what people have to say

Engine efficiency, low body drag, lower speeds and minimal weight are key in getting good economy.
Diesels do well because they make their power a very low engine speeds. Lower speed generally equates to less fuel burned per mile of driving.
I do most of my driving on a Honda 4 cyl vehicle. Newer civics get 40+ at highway cruise. Tough to beat that for its initial cost. I save the gas eating truck for only when I need to use it.
Not much you can do for the 22r other than slow down and shift short or at lower engine speeds. Air up the tires and keep it waxed plus leave the spare tire at home will help. Naturally, a well tuned engine helps. Synthetic oil will add to the mileage plus if the motor is getting old, consider doing a valve job on it and install a header.
That's all I can think of for now.....

I am in the begining stages of a 1.9 VW turbo Diesel swap into my Extra cab 4X4. In the Jetta, that it came out of, I was getting 40mpg. I think in the truck it will be 30ish mpg. It should have close to the same power as the 22RE with a few upgrades. I would think that the Toyota 2.7L would be a good swap for more mpg and should be easy if you have a donor truck (or car).
I always come back to the laws of physics. Energy is not free. More Power=More Gas. If you want MPG you need to give something up, Speed or Power.

The motor I put in my truck is the 1kz-te 3.0L 4 cyl Toyota TD. It has more power than the 3.0V6 does and burns quite a bit less fuel. On the highway I can get a bit more than 30 mpg. Right now its only getting 23-25 but its winter so it sits there and warms up for a bit then drives around in 4wd lots and the air filter is pretty dirty. But I'm making a housing for a new filter today. The stock ones are hard to get. Also my revs are not correct on the highway yet as it is geared for 31'' tires and I've got 235s. The extra 2 inches will drop the revs down some and make it better. I think on a long flat haul I should be up around 34mpg or so having clean filters and right tires and stuff and not using the power it has all the time. I have heard that the 3L 4 cyl NA diesel is quite good on fuel. But doesn't have much power till you put a turbo on it and turn the fuel up a bit. You would be suprised at how many people have been and are going the route that I've gone.

My vote would go to the VW turbo diesel or the 2.7L 4-valve motor. You're looking for the motor with the highest volumetric efficiency in the usable RPM range.
Who cares?
With fuel at $3/gallon and driving 300 miles a week, I care.. :-)

for fuel efficiency you will want a toyota diesel...now i dont know how much hp and torque they make..but i do know how much the cummins 4bt makes...WOW...105 hp..280lb ft of torque...then..with the turn of just a few screws...over 160hp..and over 400lb ft of torque....thats amazing..all with around 25mpg...even if it got terrible mileage... i make bio-diesel b-100...so it dont matter..at $.60 a gallon....i could get 5mpg and still do good...lol...so 4bt swap...here i come...(eventually)

so what about a newer car engine?
ive seen pics of the supra engines in, what about something else?
would a new car engine bolt up to the r150/r151??

You'll need to look to the most common swaps in terms of bolt in. The 2.7L motor is fairly modern, as is the VW motor. The supra 7MGTE and 7MGE can be bolted in also - most require a bellhousing change.
Alternately, you'll need what I deem "significant" fabrication skills to mate the existing driveline to a modern motor.. .

i have been checkn swaps and it's difficult to justify engine swapping for fuel efficiency reasons alone. you'd have to drive a load and that's still with gettin parts for a great deal and wrenchin' yourself. i have the 3pointslow and will goin with the 5vz.
i am mathmoron but i tried to come up with a theoretical:
100mi/day >36500mi/year est to 40k/yr.
40k mi @ 20mpg = 2000g and 40k mi @ 30 mpg = 1333.33g. right so far?
and at $4/gal for gasoline the annual difference is $8000 vs $5333 which is roughly $2600. thats with a 10mpg difference driving 100mi day at $4/g. in reality i think realized benifits would POWER and less mpgs due more fun and a heavier foot.

The 22re head is the problem really, your right. 2 valves per cylinder sucks and the flow of the current head is terrible as well. Someone should make a diesel kit for the 22re. A head and some pistons with a side mount distributor style injection pump, sign me up.......... The rest of the enigne could take the pressure I bet.

Good swap! Dump that Ford Ranger for a 2.7 Tacoma to use as a donor vehicle. I bet after selling body/suspension/axle parts you could damn near break even, and the best part of all.....Fordless.

I like the idea of a bio swap. it just seems like the only way to make the $$ of something like this worth while. otherwise you should be doing it for the desire of more power instead of worrying about fuel economy cuz otherwise your spending $$$$$$$ to save $.
