The 2zr-fe engine swap guide

[ArmstrongRacing]

For those of you with a auto transmission: If you use a Xd harness you won't need this step. If you used the Corolla harness pin#57 needs to be moved to #58. This is for the Sl/Slu+ solenoid.

[ArmstrongRacing]

This is the lock on the main harness connector(C20). You have to pop this grey tab out about 1mm before you can release the pins.

[ArmstrongRacing]

Next you need to slide a small pin into the pin release hole. Pull on the white #57 wire and wiggle a bit until it slides out.

[ArmstrongRacing]

Pop out the little rubber seal in pin location #58, and slide the wire in until it clicks. Install the rubber seal back into #57, then push the grey lock tab back in.

FYI: This pin removal/install procedure is the same for the ABS module plug, in case you used a Xd trans with no speed sensor.

[ArmstrongRacing]

This is the last of the auto trans related wiring. Because the Corolla/Xd have different ground circuits than the Yaris for the Sl solenoid, you need to open the trans harness about 8" from the plug and cut the blue wire at pin #9. Pull the wire out of the harness while still connected to the connector and attatch a eyelet, the ground the wire to the trans case here.

[ArmstrongRacing]

Now that all the wiring is complete, lets be sure the ECM is happy........yep, time to charge the a/c and take it for a drive...

[ilikerice]

YAAAAAY!

Congrats....

Only reason I am upset is because you have a CamCon that you were going to tune with the 1nz and share a mild tune with me.................

[ArmstrongRacing]

Thanks man.

Haha, Im sorry about the tune.....I never had a chance to install the Camcon either, life threw me a lemon and I had to make a batch of oh-so-sweet lemonade!

On a side note.....holy crap this car is a BLAST!

so was the faulty trans ground the reaosn for the previous CEL that was regarding the torque converter?

It wasnt a faulty ground, just a difference in how the Corolla/xd is wired inside the transmission valvebody...2 wire changes and done.

[tmontague]

I see, but that wire you just grounded above was the reason for the torque converter cel?

[ArmstrongRacing]

That's correct

[ern-diz]

Why, oh why, are you holding out on the first start and test drive vid!

[ArmstrongRacing]

Ive edited the videos together up to this point, I need to do a test drive video along with some footage of this weekends autocross.

[aspro]

Im curious to see your time differences in autocross between the 1nz and 2zr... Ill be watching this closely. Good job btw, i bet a lot of people have been putting diesel fuel in there yaris' to justify an engine swap... Or maybe thats just me. :p

[invader166]

I wonder...is there a big weight difference between the 2 engines?

[ArmstrongRacing]

On every engine Ive owned Ive had one of these guys. It never hurts to monitor your oil pressure especially when you push the engine like we do. This is a decent quality electronic gauge with a sender(not the nylon tube). Reasonably priced at $84. I normally remove the stock "dummy light" oil pressure switch and install the gauge sensor in that port. You'll also need Auto Meter adaptor #2269 because the block port is BSPT vs most oil pressure senders are NPT.
