Swapping in a Gen 4 Prius' 2ZR Engine into the Prius v

Too late I guess. I already paid for the Gen 4 engine from a local JDM place. Should be delivered later tonight. The engine looks to be in good condition, no leaks that I could see, low miles, no cross threaded drain plug. Plus it's coming in at a little over $1800 with delivery included. To get a similar build from Hybrid Pit would be over $2600 plus whatever the delivery fee is and however long the lead time is. I'm hoping to have mine up and running by this weekend because it's really tough being a 1-car house.

I did think about replacing the head gasket but reviewing the videos and such, this should be faster and "easier". I'm willing to take a chance. If I still have issues, I can always attempt to change the HG on the old engine.

 

You do have to use a lot of your gen3 engine on the gen4 to make it fit including the egr system. Plus some wiring and cooling system changes.

 

Just going to throw in there the Gen 4 block Gen 3 head swap I did never overheated. Possibly due to NOT having to reroute coolant lines required to use the Gen 3 EGR cooler with the Gen 4 head? I’m just guessing here. But I did have to flush the “mechanic in a bottle” out of my system with vinegar/distilled water and clean a glob of junk out of the thermostat in the Exhaust Heat Recovery Tank.

 

with the Nexpower V2.5 car still gets 610-625 miles per tank on flat ground driving easy.
