Can't tell you how much I appreciate the time and detail in your video! I have just decided to forgo the head gasket repair I was about to embark on in favor of a gen 4 engine swap. I'll be hunting for the engine today as well as looking for more info about your battery swap! Thank you sir!!
You will need to ensure the EGR components, and the EGR passages, are kept clean, say every 50k miles. To avoid a repeat. The mechanics mention of sleeves in the block is not what prevents EGR clogging: 4th gen EGR is revised in many ways. And your EGR is still third gen. Which is smart, 4th gen EGR is problematic in 3rd gen vehicle. But yeah, continue to keep your EGR clean. See first link in my signature at PriusChat, for links/tips/info on how to DIY this. 😊
At .20 sec it still shows the misplaced PCV valve close to the oil at the bottom of the engine unlike the gen 2 where the PCV valve is at the valve cover at the top of the engine like almost every car has, if you need to swap the head and the engine is still good on the Gen 3 then just replace the head gasket why go through all this, either way you'll get another 200,000 miles or more on that new head again anyways, thank you for the video and the time you spent making it
How was the ECU reprogrammed so that the ICE doesn't start every time the car is started, so that it behaves more like 4th generation Prius than 3rd generation. Thanks.
Awesome, so definitely the improvement between Gen 3 and Gen 4 has been electronically. One more sign that electric engines are the future! Thanks for sharing this great review
Jack loves his Gen 3.
Gen 3 design is definitely the peak Prius design
I wish you had a picture of the transmission side of the engine just to look inside of the transmission housing would be nice, thanks for the video
@hybridapp Very excited for the next videos. If the engine is the same… I wonder if we could all get gen4 flashed ECUs on Gen3?? Hmmm
I'm wondering about what Toyota did to the Gen 4 to eliminate the problems with the, if it doesn't eliminate the EGR problem what is the sense to do the swap? If you still have to do the EGR cleaning I don't see any reason to swap.
I did gen4 swap for my prius v at Golden kp around 2017 .that time engine was so cheap because no one need gen4 engine and gen 3 engine was asking around 1600. City mpg shoot up getting 46 to 48mpg .but highway mpg stay the same. The car feel like slower too.
Makes sense the 3rd gen prius engine actually had a tiny bit more torque and hp.
No problems so far other than being slower?
What’s the cost to replace the engine with a gen4?
Wondering the same thing... Replacing my head gasket and lapping the valves now and kicking myself.... I probably should have just swapped for a Gen 4 engine after buying all the specialty tools, time expense it is taking to tear apart the engine, and clean it.
I thought Tony said the gen 4 exhaust manifold is different, so with the swap they use a gen 3 head....isn't that the source of the problem in the first place?
I want to know this as well
No the source is with the coolant jacket passages in the block. With the heat up/cool down cycles so high in the Prius, there’s a lot of expansion contraction between head and block. The gen4 block has design changes to the cooling passages to help with less expansion/contraction
@@willyfromthehilliesso a head from the gen 3 with the block from a gen 4 is the ultimate reliable engine?
@@technicalitems731 It's way more reliable that a standard gen3 block with gen3 head. The gen2 engine is the ultimate reliable engine, hands down. The problem there is that the gen2 vehicles look like shit from a design standpoint. Honestly tho the gen3 engine isn't horrible for reliability, just nothing like the gen2. You can expect to get over 200k miles on a gen3 stock setup before the head gasket goes, assuming you keep up on the EGR service and regular maintenance. Still better reliability than most American cars.
I thought Tony planned to put the Gen3 head so that the you can use the same Gen3 exhaust manifold. Saw on the last video Tony mentioned that there was a slight difference with it.
Never mind.. I guess Tony said he sent the head out to be rebuilt then put it in. I was hoping I could see that in the video :)
It doesn't look like they changed the heads over? That's why his old plastic cover couldn't go back on, because it didn't fit the gen4 head ... I'd love it if someone could clarify.
Im surprised you guys didnt put on the cat protector at that moment while you were at it.
I follow the steps of another guy for swap 4 gen into 3 gen, but I thing we made a mistake using galvanized pipe for the lower radiator hose
Hi what about ECU tune with new engine. Does it required to tune. Also hose pipes any modification required
What about plugin models?
Awesome upgrade, thanks for sharing. Also the prime isn't that ugly haha
when will you have a video on the ecu program? its been 2 years!! i love your videos!
Thanks you...very informative video
Did you need to recharge the AC compressor because it looks like you didn't disconnect any hoses, thank you for the video and the time you took to do it
Great video!! I'm just curious about something, everytime I buy something for the Prius they ask me for details like the model, in my case is a Prius V five with a certain VIN letters and numbers that seem to make a difference on motors, does it matter from which model Prius is the motor coming from?
Something about the 5th letter of the vin needs to be A or B
Hi Jack! I’m wondering what information you found out about the ECU? Were you able to flash the GEN three ECU or swap with the GEN four ECU? Just curious…
I did the same swap but opted for a new/rebuilt gen 3 top/cams with the 4gen block so it came out looking like a gen3 and can still use the 3rd gen engine cover not sure if that was a good idea ? the mechanic gave me the option to keep it all 4th gen or modified to fit with the 3rd gen top/cams and decided for the oem 3rd gen look so basically I have a 3rd gen top with 4th gen bottom
wow how much was that job?
@@imthedrivingcrooner your miles may vary I’ve seen this work in my area go for as low $2500 to as high $4500 you have to shop around and find what fits your budget I found a shop at the lowest end of the spectrum best of luck
Where did you get it done? And how is it running now, no problems?
the flag on your arm is facing the wrong direction btw good video looking into a 4th gen swap if i can find the right priced motor
how much did this whole job cost including the engine?
Did you use the gen 4 ecu?
Have you tried swapping out the ECU
Hi can you put coolant hoses diagram. Any changes required in hoses while swapping gen4 engine on gen3 prius
What did he do with the water pipe that comes out of the head, I have seen others do some time of mod curious as to what he did on your?
wire bristels are in the engine use a scraper
Check out the seat covers at 29:06. What kind of covers are those?
When my prius head gasket goes bad am just going get fix in Tijuana lol
Do you have a long term update ??
Jack, I enjoy your videos. I recently swapped my the engine of my 2010 Prius with a Gen4 at the same place you did your and Tony was the tech.. two days after, I got the P0A80 ODB code which Dr Prius App says it’s the batter pack. I replaced my hybrid battery a year ago with a reconditioned battery so is it possible the error code is related to the engine swap or perhaps a bad blade in the hybrid battery.
Where's this workshop located?
I'd say another bad blade cell. Some of these guys are not reconditioning the individual cells properly. And every hybrid cell on ebay have no milliamp rating... voltage of a cell tells me nothing.. (need milliamp ratings)
@@uri78mxI think it’s the one in garden grove California.
Where is this workshop located?
I have engine pinging on my 2011 Prius
Do you think I could get a engine swap with my cats extended warranty
guy you were no having problems with bleeding and purge
No prob passing smog in CA? CARB approved upgrade?
What shop did you use
👌🎉
I have a 2014 Lexus CT200H, which is pretty much a Prius. Its beggining to knock and I have replaced EGR Valve and clean the system I also replaced the ignition coils. Were are you located and what would you charge to do this?
I'd would be nice if you could speak up louder about the main changes and points.. oil cache cans are no good in cold climates they freez solid.
What is the contact information of the shop? Thinking of upgrading too!
Never once showed a view of the water pump side of the engine.
@hybridapp I also have a Prius gen 3 and swap to a gen 4 and no one in the New York area can get the motor to work properly this is including Toyota Service, I keep getting a P0401 insufficient airflow. Any help will be greatly appreciate it
p0401 is egr flow
Did you fix it? Any updates
About how much does the engine swap labor cost?
He said it took about 4 hours.
@@808zhu I guess it's possible if you have the knowledge and tools you do it everyday, us DIY'ers will probably take a few days
I called them and they said $5k 2 yr warranty for the gen 4 bottom
I have a question : my 2009 Lexus GS450h uses nickel hydride cells for its hybrid battery. Can I swap in lithium cells as a replacement or is that dangerous since it was originally installed and meant for nickel hydride battery as factory installed.
Good luck finding lithium batteries.
You need a good bms for them
@@gloomweed318 you know this guy's has them manufactured specifically for this right?
In the middle of doing this myself, hoping to get it done tomorrow morning. The 4th gen actually has 13 less horsepower than the 3rd gen. Personally I'm unaware of where this decrease comes from IE: Ecu tune, Injector size, fuel pressure or the intake redesign, but its supposed to be more efficient so the horsepower doesn't really matter.
It's a difference in the calculation method, accurately estimating hybrid horsepower is tricky.
How did it go? Any updates on your swap?
@@jbek9779 it went fine, had to custom make a coolant hose for the driver side. Have 2500 miles on the swap now, no issues at all. Getting ready to sell it though, automatic transmissions just bore me too much so I bought another manual.
@@aaronnagy5430 fantastic!! I’ve just bought an engine from 2019 prius.
@@jbek9779we’re you but the engine and how much you pay ??
Where can we find the catch can bracket? 13:31
Look on Prius chat. There were a few people selling 3d printed brackets for the gen 3
i can't see MG1
At what mileage did your head gasket blow?
245k for mine
Swap Odometer to 50K miles 😁✌️
At 13:00 TH-camr Dala has upgraded his Leaf inverter to higher power.

Maybe you can work out how to upgrade the inverter in your Prius. 🤔
May be may be not
i get triggered by the backwards flag on your damn shirt every time i see it
I would hate these guys hovering and asking me questions all day slowing me down! Hope they paid him for that. Come to your job And ask what's this what's that
