The 2zr-fe engine swap guide

[ArmstrongRacing]

...And so it begins. The 1.8L dual vvt-i 2zr-fe is a relatively new engine, released in 2007. This engine produces 136hp/129ftlbs at the crank in stock form, and is a smog legal swap when done properly. There is great aftermarket support with people making 150hp n/a with flow mods, or 200hp+ with available superchargers and turbo kits. I chose to get my swap components from a auto recycler instead of buying a scion xd. My engine is from a 2013 Corolla with 34k on the odometer(the valve cover writing is wrong)...a great find. My car is automatic and Ive kept the auto for now to check compatibility. Lets start, here's whats needed:

1)2ZRFE engine with ALL components and accessories from a 2009+ Xd, Corolla
2)ECM from a 2008-2009 Xd applicable to your car in auto or manual trans
3)Xd engine harness also applicable to your car and transmission choice.
4)Xd RH and LH engine/transmission mount and brackets
5)Xd exhaust midpipe
6)Xd intake AND MAF sensor
7)Xd or Corolla flex plate(auto), flywheel/clutch(manual)
8)Mini-add-a-circuit and soldering equipment

*With the help of other YW members, I have started a collection of 2ZRFE parts to make everyones swap a little easier, just contact me for details!*

Read through the entire thread to learn as much as possible before beginning. Good luck!

If you go through a recycler you need to prepare yourself to make a ton of phone calls and be clear about what you need and how you want it. Expect to spend roughly $3000 total for everything needed. You can also buy a entire wrecked car if you like, but it will cost you more. You want everything that was originally attached to the engine, including ecm, exhaust, airbox(xd), passenger engine mount(xd), ect. Ill cover all of this throughout my install.

The first thing I checked was compatibility with the yaris c50 transmission. The 2zr and 1nz flywheels/Flexplates are the same size, the only difference is the 2zr has 8 bolts where the 1nz has 6.....so use the 2zr flywheel and your 1nz clutch.

The bell housing flanges on the 2zr and 1nz are also the same, both are a 9bolt 2-o'clock starter orientation. Apply a little grease to the dowels, and you can use the 1nz starter.

Yuppiii!!

Awesome! Great information.

I ordered the xd airbox, engine mount, and maintenance items today. They should be in tomorrow, now I just gotta get an ecm and start the wiring.

I can help with the wiring diagrams if you have to modify anything--I just snagged copies of every year xD and Yaris that I could find on the Toyota tech site.

On a format note: I'm not sure if the file size is the reason for only one picture per post, but it would be much more helpful to have the whole process in the first few posts instead of having to sort through lots of replies to find the content.

[ArmstrongRacing]

My plan was to document each step carefully with one picture for each step. Yes there will be replies to read through, but some of those comments could be good information in case there are questions.

Can't you just edit the last post and keep adding to it. Upload the pictures to photobucket.com and link the pictures. You can add as many as you want to that way.

I went through the wiring diagrams today and verified the 2zr ECM(automatic transmission) and harness are mostly plug-n-play with the Yaris U340E. For you guys using a manual transmission, you need a manual trans specific harness and ECM.

Could you clarify a little more on this? What do you mean by U340E?

One of my other concerns is emissions. When you swap to a different car ECM, I'm wondering what kinda of problems that will create when one goes for their annual emissions testing? Doesn't the computer store the VIN info, and I wonder if it will throw a red flag when the emissions testing machine is hooked up to your car, and the VIN #s don't jive?

For those interested in the emissions question, I did some asking around and a little research at www.cleanairforce.com, which is the state of Georgia's website for emissions standards. It appears, or at least in my case, if you put an engine in a car that was never put in that said car for USA production, and that car falls under emissions standards, it then becomes what is called a "grey market vehicle." I have been told, but have not verified, that it is possible to get a "emissions waiver" from the state, if it can be demonstrated that your car will still pass emissions standards for your year make and model of car. I say that I haven't verified this, because what I found on the website is kinda vague, and this info came from the emissions inspector that recently had tested my car. I would definitely want to confirm with the state, that what he said is in fact the case. The emissions inspector did say that by putting a different ECM in my car( IE from a Scion XD), would throw a read flag, because the info coming out of the ECM would not jive with the car being tested, so it would fail without the waiver. Not sure if this info would apply the same to others in different states, but IMO, it would be something I would check on before doing the swap and spending the money.

I'm truly not trying to be a buzzkill, because this swap is AWESOME, and I really want to do this to my car. Just something to think about and investigate if your car is required to meet state emissions standards.

Good to know. I found that the Yaris ECU pinout is not compatible with the xD wire harness on either connector. Have you addressed the issues with the smaller connector on the ECU, since some of it goes into the interior? What about the end of the engine wire harness that goes into the engine bay relay/fuse box?

**EDIT**

Here's my spreadsheet for comparing the pinouts of the Yaris and xD ECU connectors. I will have to look at the EWDs again when I get home at the end of the month to see what the missing/conflicting names go to. Hopefully that connector just needs to be pin swapped.
