it'd be cheaper and easier for you to swap in a 3rz

what is a 3rz?

Dieselyota · 02-01-2006, 07:48 PM

Yes, there are strict laws against importing a vehicle not originally built for sale in the usa. The cost would be "approx" $5500-6000 depending on the truck and the clip. Diesel swaps are best left to people with experience in toyota diesels. Alot of folks get suckered into paying for someone to swap in a diesel and they "learn" on their dollar. Experience goes a long way when you're dealing with swapping in a powertrain not sold in the usa.

stumpbum21 · 02-01-2006, 08:07 PM

how long does it take to get the half-cut? how long for the job once the donor is in your shop?

Dieselyota · 02-01-2006, 09:27 PM

It depends on the vehicle. The half cut usually takes a week to arrive depending on availability. From there, depending on what we need to do we can have it done in 7-10 business days.

Thats the best way to do it!

The motor mounts match up with the 22RE.

Praufet · 02-02-2006, 03:15 AM

3rz is the 4cyl from 3rd gen and later 4runners/tacomas

photomike72 · 02-02-2006, 08:03 AM

is the engine rebuilt/tuned up/certified good to go at any point or is it just a straight swap of a used engine?

Also where would I take it as far as a mechanic goes? I would assume that since these engines were never sold/imported here that finding a good mechanic to work on this engine for the 'heavy' stuff would be hard to find.

I love the idea, I just want to make sure that it's practical for me and my truck.

Thanks for the info!!

Dieselyota · 02-02-2006, 08:28 AM

Well, diesel engines were not sold here so getting someone else to work on the "heavy" stuff will be tricky. Parts are available from your local dealership. If anything heavy does go wrong, replacement engines can be had fairly inexpensively. It's the initial swap that is expensive because of all the wiring and accessories you need to install. The engines are sold to us used with no warranty. They send us a video of the truck running/driving and they have their mechanics look them over before they even ship them out. If you keep up with routine maintenance, these engines are bulletproof and provide excellent mileage. Once you drive one, you'll want one...guaranteed!

stumpbum21 · 02-02-2006, 05:29 PM

do you cut and re-weld the frame? if so, how strong is it? some states will classify a re-welded frame as a wrecked vehicle. have any of your customers had a problem in this regard?

Dieselyota · 02-02-2006, 05:47 PM

Nah, the only welding is to the motor mounts for the engine only. The welds are approx 1" in length total on each side of the mount. I wouldnt worry about that at all.The frame for the half cut isnt used at all. We take the mounts off of it and scrap it.

unless they are super rich, they will not hang onto them past 10 years.

also in reference to legality, if the engine was never sold in the us, it is specificaly illegal to swap, and per texas, no gas to diesal conversions and vice versa.

Dieselyota · 02-06-2006, 07:37 AM

You cannot "legally" swap in an older gasoline engine into a newer vehicle (ie. a ford 302 carbureted v8 into a 94 toyota 4x4). This is for emissions reasons. Because you are technically circumventing the emissions controls originally placed on the vehicle and creating a more polluting vehicle. The law states that if you replace the engine of the vehicle (regardless of origin) it must be able to conform to local and state emissions regulations. Since diesels have no emissions control devices (or smog controls other than egr systems) a diesel swap is completely legal. For the same reason you cannot cut your catalytic converter. Any tampering with a vehicle's emissions control devices is illegal. Anyone seriously considering a diesel swap or any engine swap, I would double check the local regulations. I know for certain that a diesel swap is entirely legal even in the super-strict state of California but there may be some state I have overlooked.

trythis · 02-06-2006, 10:07 AM

Luckily if you live in Kansas, we don't have vehicle inspections. (red neck accent--> "we can do anything we wont to!"

stumpbum21 · 02-06-2006, 07:50 PM

what type of t-case comes with the half-cut: gear or chain?

stumpbum21 · 02-06-2006, 07:52 PM

what type of t-case comes with the half-cut: gear or chain? and does anyone know of a company that makes driveline parking brakes? my t-case is the chain drive and all of the co.'s i've looked at are for the gear drive.

200 hp/300 tq for a chipped engine....can the trans. and diffs hold up to that power?

Dieselyota · 02-06-2006, 09:18 PM

Dont know really! Never driven one! The australians are all over 'em though. Anyone wanna see my engine running before they cut it?

They still offer brand new 1KZ-TEs in 2000+ hiluxes. They are the same transmissions we have over here in the states.

Dieselyota · 02-06-2006, 09:42 PM

Yep. and the new D-4D direct injection diesels have yet to make it stateside but man what an engine!

irott · 02-06-2006, 10:00 PM

I wish we would get D-4Ds stateside...

I wish we would get any non-Hino diesels stateside.

Platypus1 · 02-07-2006, 05:28 AM

Hi DieselYota,

Im curious, do you guys do any other conversions for 4 runners? Like the 3.0 to 3.4 swap? or 3.0 to V8?

Just wondering. Im getting real tired of my 3.0, Ive had this truck for almost a year and still cant seem to get it running right.

thanks

Dieselyota · 02-07-2006, 07:27 AM

No, we're not real fond of gassers around here

Darrie · 02-08-2006, 05:23 AM

Hi dudes,
Being in Australia it's interesting to read how you guys are keen on the 1kzte from the land of the rising sun.. I didn't realise diesel motors are such a scarce thing Stateside as I see all the banks/cummings diesel adds in your mags all the time. Don't you get small diesels ?

Funny enough I have the exact chipped engine you guys are talking about - and its in a "grey" imported vehicle from Japan. It's also been intercooled. Definitely stick with the auto as once the turbo spools up it reminds me of a two stroke motorcross bike in the powerband with the chip turned on. I so love it when you take off from a set of lights and cream everything beside you. Everyone is so use to the normally aspirated diesels which are slow .. they don't know what hit em. Tweaked, this motor shines.

The pro's: Great mileage, has a crapload of torque without having to rev the motor to get it (most of my power is delived at 2,300 rpm), little maintenance required other than regular oil changes and filters. Its a top motor for upping the specs to deliver a really respectable output hence chips and intercoolers are popular aftermarket options.
The turbo breathes the life into these motors.. normally aspirated diesels are simply slow as a wet week. What I like about it the most is that it doesn't have good days or bad days - performance is a real constant and doesn't vary.

The cons: Alloy head is very susceptible to cracking if the motor runs out of water or cooling system is not up to spec. Japanese turn over cars quickly so maintenance is not high on their agenda. Diesels can dump alot of smoke out the exhaust if not tuned correctly. The motors are heavy. They are expensive to rebuild, although the normal lifespan is seriously much more than a petrol. You need serious battery power to crank the motors to start, particularly in a cold climate as the instant glow plugs draw some serious amps. The 4 cylinders don't make for a good towing vehicle - once bogged down with additional weight they don't perform as well as their petrol counterpart. Engines are naturally a little noisier than the gasoline motors. Diesel is common here in all fuel stations but possibly no so in the US? And probably my biggest concern would be finding someone to work on the vehicle over there who knows what they are doing. Guys here sometimes struggle as EFI diesels are relatively new to our shores.

Be aware this motor was released in Japan in 1994 for domestic consumption only. 8 years later the same motor was released in Australia as their "New Motor" in the Prado (AKA a vehicle between a 4runner & Landcruiser) with the addition of an intercooler. Latest version of this motor has changed little - it now has common rail injection for improved efficiency.

Don't get me wrong its a good motor, but most people will fit a common powerful 3.4 litre V6 (not a toyota engine) after their diesels die as these motors are much more expensive to rebuild than their fuel equivelant. And the 3.4Lv6 certainly puts out more horespower. Good thing is the transmissions and running gear on the Toyotas hold up no matter what you throw into it.

Sorry rambling on but there's my 2 bobs worth !

Platypus1 · 02-08-2006, 06:20 AM

Wow, thanks for the info!
YEah for some reason stateside only allowed us the 22re and the horrible 3.0.

Diesels in cars and SUV's are extremely rare here in the US. Why I do not know. My only guess is that the oil companies here didnt like the high MPG's and the auto industry didnt like the long life spans. Hopefully that will all change though since diesel ultimately is a stronger, more fuel efficient motor, especially with the introduction of bio-diesel.

When my 3.0 blows I am seriously going to consider this diesel conversion.

Thanks again for your info brother.
