Can a 1.5 prius C engine be installed into a 2006 prius

@SFO
Unfortunately PriusChat Rules do not allow newbies to insert links, more time and more posts are needed. I have prepared a post with links, which I will publish here later.

 

Perhaps due to the colder climate, this problem is not so widespread to think about it. And spare parts from disassembled cars from Japan are not expensive. This pump costs $ 120.

 

The thing is, in a Gen 3, the pump already has its speed controlled by the ECM at all times.

The thread is about transplanting a c engine into a Gen 2 where the ECM knows nothing about controlling electric water pump speed. The two most obvious ways of wiring up the pump would either run it full out all the time (hard on the pump) or not run it at all (hard on the engine). The WPI-to-WPO hack is just a way of giving the pump a "somewhere in the middle" signal in a car where the ECM isn't generating any pump control signal.

 

@SFO
The method with closing the wires is only suitable for Gen2, the native ECU does not know how to control the pump. For C and GEN3, this method is not suitable, you have to experiment.
The first to install the engine from Prius C, or right-hand drive Toyota Aqua, this is the author Koban4eg Vladivostok. Here is his article in 7 parts: ДВС от Toyota Aqua в Toyota Prius NHW20 — Hybrid Club Дальний Восток на DRIVE2 . It's a good job, but a lot too much. No need to change the bottom of the engine.
Here is another setup in 11 parts. The author of Gmaxby from Novosibirsk, here the 5th step is just described: Часть 3. Стыковка двигателя Aqua и коробки приус 20 американец. Подробный свап новый 1nz-fxe на приус 20 — Toyota Prius, 1.5 л., 2006 года на DRIVE2 . The pins differ by 1mm, for some reason they don't write about it, maybe it doesn't matter.
I completely forgot, GEN2 from USA have a thermos, so you need a tee: Часть 10. Схема циркуляции жидкости приус 20 американец. Подробный свап новый 1nz-fxe на приус 20 — Toyota Prius, 1.5 л., 2006 года на DRIVE2 .

 

Search car-part.com lots of 2004-2009 engines with less than 100k.
A sample attached, just have to sort by damage units.miles, then get past 0 miles pages, about page 5 or 6.

I think I must be horrible at that site. I can't find engines there.

 

Just search the websites that are shown in the images in posting #45

 

Thanks, I was missing the dash for some reason. >_<

 

I just invested in a 2014 Prius C engine for about what I invested in my last Prius, an 08. So ~$250 into so far. Go figure, don't need one transplanted yet. However, will be nice to have for when I do in one of the three or whatever I wind up keeping.

Any new updates or references? I'll try to document on Youtube next, as I've not seen where anyone has as of yet.

 

It needs a few modifications, some trimming of the aluminum intake manifold from a gen 2 Prius. Modify the pump control from the Prius C ( in Japan Toyota aqua) .

Thanks, I did a shameless Youtube video to get the ball rolling with documenting on there. Busy working on rescuing a non-touring 08 from being a parts car. Prius C Engine To Gen 2 (2004-2009) Prius - YouTube

 

What is that microcontroller unit I see there in the above article. Looks as it is described as a "controller from ev_servis." Is this for controlling the water pump and not the fan as I read like in another article regarding? Any links to ev_servis?

controller based on ESP32, reads the engine temperature via the CAN bus and, depending on the temperature, adjusts the pump speed.

As far as I understand, the pump has 2 speeds, some people install an electronic thermostat to switch to the second speed.

This motor replacement is already a standard procedure in Russia in the Far East. some services do it during the working day. What I'm trying to say is that your idea is feasible.
