Engine swap question

Oh they’ve seen and done it all.

They might be a great resource for your project .

 

That's what I thought, they are in the loop. I don't have any experience with them so I am not saying they are good or bad but others here have dealt with them.

 

There pricing can be high, but he who has the gold makes the rules.

Gotta be willing to travel sir,

I have seen Prius motors for $50 on up, price is 100% based on the time the part sits ,
Since Gen III cars blow a lot of motors the parts don’t sit as long in larger areas.
Gen IV cars are downright rare and aren’t really even sold in fly over country in the dozens.


Are you willing to have to “reconfigure” a motor with your Gen 3 sensors and some such if the Gen IV motor was $500?

I have seen all matter of engine swaps between generations of cars and I doubt the hybrid elements change the requirements (like custom exhaust, sensors and donor parts) but I could be wrong

Feeling like an adventure?
Maybe someone here lives in New York and can grab the $500 gem for you?

Next if you could come up with a strategy to fit a 1.5 liter Prius motor in a Gen III that would be the ultimate cheapskate solution
There are tens of thousands of those some as cheap as $50.

I bet motor swapping between PRII is probably more simplistic than some of the swaps I’ve seen, there just isn’t the community or demand to work through the technical issues like there are on other platforms.

Good Luck

 

Glad that you were able to connect and he had some advice for you.

 

Question, did he say what is different between the Gen III and Gen 4 engine?

I wonder if the engine block has the same part number, if it is it would bolt up and he head part numbers.

Here is a new short block.

Toyota Prius Hybrid 1.8L 2ZRFXE New Short Block Genuine OE OEM 11400-37140 | eBay

2016 1.8 has a different part number for the short block.

Only one way to find out.

 

Get the $500 Gen IV motor I linked to and negotiate it (trust me ZERO demand for Gen IV, Gen II prii are very cheap for the same reason $75-200 isn’t unusual with low miles)

Saying it doesn’t fit can mean a million things from exhaust to mounts to the oil pan or more serious issues

It’s possible your Gen iii could donate the necessary parts to make it fit.

Ah well, depends on your skills, tools, time available and how strapped for cash.

If you want quick and easy I would do what the man told you, if you like projects...

Just don’t get yourself stuck in a bind because folks like seeing the YouTube video of you breaking down GEN IV VRS GEN III Differences.

 

I was thinking about my post above about different part number on short blocks. There could have been internal differences between different generations of Prii but it still may bolt up.

Kind of like Star Trek.

Boldly going where no man has gone before.

Contact Professor John Kelly at Weber State University, he is the resident expert on the different generation of Prii.

You won't find someone who knows more about a Prius unless you go to Japan.

 

If your gonna go for it try to find a reasonable u pull, sometimes you can pull the whole engine, transaxle, harness and down pipe for less than just a long block, the more you can pull the easier it will be to “adapt” something if it has changed plugs or diameter.


Also since you are doing a favor for all priuschat owners maybe there are some helpful folks nearby, maybe a few on here could offer minor machining backup, maybe even someone could sponsor or chip in a few bucks.

Stranger things have happened, make sure you document it whatever happens

Good Luck
