    Has anyone looked into this, so far it looks like the manual water pump on the older motor and the electric water pump on the newer motor is the biggest hurdle I need to overcome. Looking for suggestions or anything outside the box method that you think would work to accomplish this task

    You're putting that engine into an older car that has no controller for electric water pumping so you would have to add or fab up some kind of control so there's always that You could use the newer block and head assembly and put the old stuff possibly on the newer blocking head Not sure about that but from what I understand this newer engine you're looking at has the flood type EGR the same valve that the generation 3 2ZZ has so I'm not sure I would want to go that route in my lovely generation too It seemingly to me would be working backwards I guess there have been some head gasket problems on the NZ engine with the electric EGR valve and the electric water pump similar to the two ZZ. And I wouldn't want to welcome those problems back into my life for what 3 mi to the gallon possibly oh no that's quite all right And in other markets I think there's a five NZ I don't know anything about it so there's that but the fact that it's an NZ derivative probably maybe make some parts useful. But fitting the old water pump to the new engine without seeing the castings and things sitting side by side hard to know Toyota's not like they used to be for these type of things like s engines and the beams engines things like that they've made it a lot more difficult for the engine swaps in these newer designs.

    I know what you're talking about as I've seen the newer model motor as of last week at the shop of a JDM importer who is very open and willing to have me 3D scan anything and hopes of making it work for not only the Prius but his Tacoma as well. I told him if he gets our fines on some list that he shops for these motors a V8 4x4 hybrid motor from one of those Japan vehicles to get it and I'd want to try to put it in his Tacoma...

    I didn't have time to 3D scan the updated Prius c motor I'll go back next week to do that however I did 3D scan the generation 2 Prius motor and I 3D scanned the entire engine bay with the motor out of the car.

    Right now I am not letting any current unknowns are known based on anything distract me for the simple fact that right now I just put a non fxe motor into my Prius and with changing the outside parts and the ECU it works and so that just allows my brain to not even think about the negatives of what can't be done because of what can't be done something tells me that there's a lot more to all of this interchangeable parts then we know and I have already uncovered quite a few different things that allows me to just think that anything can be done until I realize it can't...

    It was my plug-in that let me know and open my eyes to how smart the ECU is of these vehicles thereby my thought and even success with this and putting a motor from a different vehicle into a Prius and the ECU adjusting and making changes it needs to make to make the motor operate as efficiently as possible. So with the water pump my thought is we could use out of belt and a bracket that will hold the manual part of the pump and then tubing custom to go from the manual pump to the electric pump opening into the engine

    I think the FXE engine even the later model will still allow the water pump to bolt up It just hangs where the alternator kind of sore goes little below it and there's no alternator in the Prius although you could put the bracket I guess and hang on there but I'm not sure what you do with it. the hybrid in the Tacoma shouldn't be a huge problem You just got to get the right motor kind of like the one they're using in the Siena van or something along those lines If you want to go V8 well I guess there's that the Lexus has the V8 hybrid. So in your '08 with the non-FXE motor are you driving that now Is it on the road or is it all in in the shop I mean it's a no-brainer it'll all fit I'm interested in how does it work and drive The camshafts are for sure different part numbers but no matter certainly the computer has a certain range of adjustment obviously. Just interested if there's any balance issues between the higher horsepower non FXE engine and the electric motors any clanking

    Check it out that's a V8 hybrid motor with the CVT attached and it's a 4x4 drivetrain, the only V8 hybrid motor I would use that's in America is the one out of the Lexus LS600hl.

    So the newer motors have a bracket that the pump sits on I need to scan it as well however something in my brain tells me if I could come out to mount the manual pump where the electric one is simply adding a belt should solve all of the problems or issues with it not working, I think for me it's more of how I'm going to do the piping to go from the engine block to where the manual pump is mounted.

    With this being the first time I have ever swapped a motor and a gym too taking me longer than I expected but I should be driving here in the next couple hours

    I'm not sure why all this 3D scanning of engine bays and engines is necessary He just look up the model of car and you can see what engines can fit in it pretty quickly I mean that's not really super critical these engines are fitted in like similar cars and other countries from the factory You're just putting the same engine without the Atkins and cycle and the same chassis as the engine with the Atkins and cycle so should be a drop-in in both up affair for the most part no need to scan anything this is what makes cost go so high Just drop it in there and connect it No need to be re-engineering anything most of it just plugs up

    Knowing when to use the tools you have at your disposal I guess is a thing You get caught up into too much overuse of tools and you get not a lot of work done then you're playing with tools

    This is the thing I've learned, to make a part that's exact how it should based on a vehicle 3D scan are, if not the best method to obtain measurements that you design your part off of without actually having to take measurements.

    You know I'm not disagreeing with you in the sense that knowing you want to use your tools you have at your disposal is good, but this thing is for me and my directio. I must use my tools all the time in fact the plan is to buy $30,000 3D scanner that gets down to the micrometer level. I will I would agree on your statement not a lot of work done when you're playing with tools but that was maybe a year and a half ago these days I am really good at knowing how to prepare an object prior to 3D scanning and the proper way to obtain good valid usable 3D scan data there's a big difference there

    Take a look at the difference between the two blocks where all things water pump magic happens if I don't 3D scan and make a part that's not exact fit with both holes to keep the pressure in I'll be wasting my time so I might as well measured twice and cut once and get it right the first time

    And I think you might be missing like the point I'm making Atkinson cycle and otto cycle it's not based on the engine is my belief now... it's based on what the code is in the ECU..
