Cumming R2.8 for 1st Tacoma or 3rd gen 4Runner

An engine in the bed defeats the whole concept of a truck!!

I don`t feel like doing the Math to convert Horse Power to Watts but our 25,000 watt generator is to heavy for a Tacoma about 2000 pounds .

The more thought I give this swap the more interesting the challenge becomes from a dollars and cents point it is quite stupid .

Though being able to say I did this might be rather fun

 

Here is the one 75kW 900kg

If you need your bed there is a trailer option for the generator. Keep in mind that the truck weight will be reduced by all engine bay guts that will be removed.

By the way the price for generator and electric motor combined will be less than 75% of that R2.8.

 

But did he keep the 4x4?

 

If you are willing to do the work, go for it.

But you should probably learn how to spell "Cummins" either way. You're 0 for 2.

 

I feel your pain, I put a stroked chevy 383 in a 91 4-runner after a couple of blown head gaskets from the 3.0. Tremec 5 speed, ford 9" in the rear, I was on a first name basis with the folks at Downey Offroad and Atlas adapter. 10-12K later it was done, kept it for a whopping 6 months then sold it due to transferring to Alaska. 14 gallon tank and 10.5 miles per gallon it did not make any sense to keep it.

 

First thing I noticed too! I’m intrigued.



OP- why do you want to change the engine to do 33s? I’m on 40s with the 3.4 v6 and I can use cruise control on the highway.

You could always go this route.

OK, it had a posted date of 2017, but you get the picture.

Looked at these a while back too, little pricey.

Before everybody gets excited by 20-years old Hilux Diesel make sure you check the spec for this truck and the engine. It may be cool to have it in USA as a collector vehicle, but not as a normal daily use truck. Hilux were build to be a farmer's truck. That means the ride comfort is not even close to what we have in the 1st gen Tacoma. The diesel in Hilux (that era) was wimpy and thirsty. Acceleration of a turtle on drugs, and still you get 20mpg or less. It is simply way, way worst that gasoline powered 3RZ or 5VZ on economy, performance and quality. There is only one advantage of Hilux that era over 1st gen Tacoma: payload. The suspension was built to handle full load and drive on bumpy dirt roads, where Tacoma would bottom out or break leafs. But that comes with the cost of ride quality which in Hilux is close to a dump truck.

From time to time I see posts of this forum prizing Hilux, but really if you compare Tacoma to Hilux you would see that some don't realize how great Tacoma is. Yes, Hilux is tough (hence "Taliban truck") but if you want to use it on a street be prepared to drive it like a farm tractor. Pick-up market is USA is very different from the rest of the world, and because of that Tacoma was born and Hilux is not sold in USA.

 

One other thing though Diesel !!

One of the Hurricanes a few years back Electric Out for 9 days .

The two 5 gallon cans of Gasoline did not last long.

I hardly put a dent in the 500 gallons of fuel I have most of the time.

The Diesel Hilux is not imported so every one wants one being the next thing to a farmer I don`t mind a farm truck .

 

Had a 2007 Ford Focus 2 Dr Turbo Diesel 5 Spd in Ireland when I lived there and absolutely loved the thing. Almost contemplated pulling the motor out and shipping it separately back home but common sense told me no. Anyhow it was a fantastic vehicle, fast, surprisingly quiet and very torquey for what it was. My neighbor had a no frills Hilux and the thing sounded and drove like a tank, I was honestly surprised how loud and bouncy it was. Reminded me of the Suzuki Samurai's.

Like anything else if you have vast amounts of duckets at your disposal then it would be fun....maybe

 

yeah, those Hilux motors from 20 years ago weren’t so great.
Are you talking about the L motors? Or the 1KZ motors? I know very little other than what I’ve read recently.

These guys will do a swap but it’s a lot of money.

However, they will also do a veggie oil system as well. I’m a chef. I have access to 5-15 gallons of used but not horribly used fryer oil per week. The cost of the swap would work out in 7 years for me at the rate I drive my truck (it’s not a daily). That’s a really really long time! But the extended range and low end torque make it tempting.

Or I can just leave my truck alone. Which is what I will most likely do.

 

Actually I was thinking about 2L-II used up to 1997 - it has 2/3 of HP and half of torque comparing to 3RZ and made Hilux use close to 20mpg.

Of course comparing modern turbo diesels with common rail and dual turbo to 25 years old gasoline engine does not make sense. If I would modernize Tacoma by putting modern engine in it I'd rather picked 1GR-FE, same as I have in 5th gen 4Runner. Funny thing that 4Runner despite being much heavier gets better mpg with almost twice more powerful engine than my Tacoma. I'm not sure it the reliability of this engine is as good as my old trusty 3RZ-FE, time will tell.

 

The engine alone has an $8000.00 entry fee before you even begin the swap. Go for it and report your findings to the good people of TacomaWorld. I'm a diesel mechanic in real life and I'm sticking with my underpowered reliable 3RZ.

 

Check out this website if you haven't already, they do a diesel swap for Toyota's

Very interesting read, @uurx. They speak the truth. I have a friend/former coworker who now works on almost every OEM's diesel engines. He's pretty unbiased because he knows everything eventually breaks. He may even subconsciously favor Cummins because he's had good luck with his Dodge diesel pickups. He told me those R2.8 engines are very unreliable (not his exact words) and have a poor reputation in his little corner of the diesel world.

I told him a lot of off-road and overland enthusiasts are drooling over this engine and he thought that was hilarious. He told me they're highly annoying even for an experienced technician with every resource on hand, so for hobbyists they will have to invent a new word that's worse than "clusterfuck."

 

nothing lasts for ever, and anything worth the while comes at a cost and a sacrifice

I remember when the r2.8 came out I was super hot on the idea as so many where as well at the time

however time is the true ultimate test and the r2.8 just was simply not what we all wanted it to be....

 

I like the basic concept...
I don’t think you’ll get much performance out of it. The diesel can’t magically produce more hp in an electric motor through a generator without a very large capacity storage device. That and computer control makes this swap more involved then swapping out a motor alone.

Now, if you had a long enough extension cord or ran it like a trolly....then it gets real basic and easy.

btw, electric motors theoretically deliver their torque based upon limiting factors. So it’s not unlimited. But, the torque curve is very linear so even just 200 ft lbs should be very effective for off roading in a light truck, with excellent drivability.

I personally wish they could make a series hybrid like you suggested, but the mileage would not be that great. But I would live with that regardless.

 

Is this not the kind of information one would hear about when doing the research before reaching into the vault to break out the gold to pay for anything.

I might have missed it but has the OP even been back ?

 

No, everything online is borderline infomercials OR people on forums jizzing themselves chatting about unrealistic diesel swaps.
