First US 2ZR-FE Yaris swap gains exposure

Sounds good to me! Perhaps include a "bravery" rating as well, since some options would include non-trivial modifications to the drivetrain?

Stock Yaris C50 - Bravery: Sir Robin
Pro

• Keep stock axles and mounts
• Direct fit
• Final drive is taller: higher top end speed in each gear

Con

• May be limited in power handling above 150 whp (axles)
• Final drive is taller: less torque/acceleration in each gear

Stock xD C50 - Bravery: Sir Galahad
Pro

• Keep stock axles and mounts from xD
• Direct fit
• Final drive is shorter: better acceleration in each gear

Con

• Must use axles from xD
• Final drive is shorter: lower top end speed in each gear

Custom gearbox internals - Bravery: Black Knight
Pro

• Get the ratios you want for almost every gear
• Get the final drive ratio that works for your application
• Excellent opportunity to add limited slip

Con

• Requires mechanical knowhow and proper tools (the service manual is one of them!)
• Can be VERY expensive to source new OEM parts
• Can be LUDICROUSLY expensive to source aftermarket parts
• Will require extended downtime to build the gearbox, can be worked around by getting a donor gearbox and building it before the swap

^that is awesome! Thank you!

Im also starting to contact the Lotus guys to see how the 2zr handles track abuse and if it needs cooling upgrades

Like so many other people that have posted, I'd be up for getting information on the order of a DIY.......

I'm in the frozen north, land of Igloos and Universal Health Care............so having a paid swap done in the USA is out of the question.

This seems a little bit easier than a K20 swap

UPDATE: Ive completed my move to San Diego and have started searching for 2zrfe's. Ive found a few at dismantlers out of Corollas for $850-1000....but not complete engines. I will be purchasing one of the longblocks to test fit with a Yaris clutch and transmissions asap.

I've been watching this post from the start and have been wondering if there is a more common (AKA cheaper) LSD option for the XD? Or another trans that bolts in?

Also, good job on the swap!

Generally, no. The "cheapest" option is a Phantom Grip, which still runs a few hundred dollars and requires complete disassembly of the stock differential to install. There was an OBX-made torsen style that was hit or miss for being a grenade for around US$700 iirc, but I haven't looked for them recently. You might be able to find an OEM LSD in a junkyard if the stars all align for you, but I use US$1000 as the benchmark for adding limited slip of any kind that isn't going to be a gamble down the road.

Thanks for the reply. Yeah, that's the price range I was finding as well. I just can't justify spending that on my Yaris even though it would make a world of difference. If I could do an easy motor swap, get more power/torque and LSD I'd be all over that though. As is, I give you guys credit for the work you've been doing; trying new things is what hot-rodding is all about.

Cheers

This is exactly my plan with my personal 2zr swap. I have a spare Yaris trans I will upgrade with the Xb final drive and a LSD....given That the yaris trans works with the 2zr.

For what it's worth:

On toyodiy.com

2008 Toyota Yaris NCP91 with a 1NZFE 1.5 Liter engine, uses a C50 manual trans part # 30300-52360.

2008 Scion XD ZSP110 with a 2ZRFE 1.8 Liter engine, uses a C50 manual trans part # 30300-52360.

Same trans, so my guess would be that a Yaris trans will bolt to the 2ZRFE engine, or at least in this case.

I've got a 2007 Yaris with an auto, and if I did this swap, would go consider going manual, but the manual trans part number for my year is a 30300-52510. I bet the difference has to do with VSS sensor vs. getting speed off of ABS, as my car doesn't have ABS.

Checked the auto trans part #s, they are different from a Yaris and a XD.

I'm just wondering if you can run the Yaris computer with the 2ZRFE, or if you have to swap out with an XD computer?

[ArmstrongRacing]

^What oem lsd are you referring to?

[ArmstrongRacing]

Wow...thats more evidence suggesting compatibility. Thank you.

Anytime you swap Toyota engines you are required to swap in that corresponding ecm. And yes the 2zrfe uses a different auto trans, I haven't looked into why though

If someone was in the market for a used Yaris and they did it smartly depending on how much equity they could have in the purchase it would be smart to roll the swap right into the note ;-)

sooooo........................................why aren't we also talking about the 2Litre- 3ZR-FE ?

Is it because its not as readily available in North America?

Does anyone (CTScott???) know if it is dimensionally the same as the 2ZR ? (ie:, is it just a bored and stroked 2ZR?)

Either way, I'm still anxious for more information because I was thinking about some other "next level" mods for my 1nz-fe, and it seems more cost effective to put that investment into a swap.

We briefly discussed the 3zr, and yes it will probably work but like you said...its not available in the US. The 2zrfae just now showed up here and it was developed in 2010!

If I had some assurance that the 2 litre was the same (externally) as the 1.8, and if I knew that it would bolt up to the 1nzfe tranny (like its looking the 1.8 will) than I would almost go through the effort of importing the 2litre (I know a guy ) ......................................

1ZR, 2ZR and 3ZR are more than likely the same as 1NZ and 2NZ. They're all different displacement but otherwise use the same parts. Unlike the 1ZZ and 2ZZ in which are totally different engines.

[ArmstrongRacing]

I don't believe the 3zr at 150hp is worth the additional effort, and it would not be a legal option. The 2zr has n/a bolt-on potential to 150hp, or you can boost it like Lotus does

Up here in the land of Igloos / clean water and Universal Health care, "Legal" engine swap is not really on our Radar.

All we have to do for "Emissions Testing" is to plug a scan tool into the OBD port and check for CEL codes. Thats it.

They don't even run sniff tests anymore (for tail-pipe emissions).

I literally have one friend of mine that has a Stand-Alone ECU that runs his car, but just for shits and giggles he keeps a bogus ecu powered up and "properly" setup in the car (Connected to the OBD port) just so that when he has to get a "DriveClean test" (only once every two years), he just takes it to the testing facility , they connect their scan tool - they see that there is an ECU present.. that isn't throwing codes and thats it.

I could frankly install just about any motor I wanted as long as it gave a reading through the OBD port and it didn't show a code DURING the test.


Now back to our regularly scheduled engine swap discussion.
