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.

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?
