2zR swap worth it?

Also Ive negotiated a 43k engine with complete exhaust, accessories, MAF and mounts for $600 from a 2011 XD? It’s auto and my 07 Yaris hatch is manual so I didn’t ask for the harness or ecm. Is there something else I should ask for from that car? Airbox is broken :(

I agree with the comments about not being afraid to get up into high rpms--the 1NZ really wakes up at 4k and will pull up to about 5500. The 2ZR with a high flow exhaust setup will pull hard all the way to redline at 6500. On ramps are a non-issue for me, even if traffic is doing 75-80 mph. =)

Definitely spend some time going through the existing build threads. You're fine to use the Yaris gearbox with the 2ZR. That's what most of us have done initially and it allows you to keep the stock axles. You'll need to source an xD ECU, engine harness and all of the xD engine/trans mounts (both the vehicle and engine sides!) for whichever type (auto/manual) you choose. You can use an AT harness on an MT swap, but not the other way around.

I wouldn't worry about going with the xD trans/axles/hubs unless you're planning on making over 300 bhp. Garm did a build on his 1NZ that dyno'd over 350 bhp on stock axles and 4x100 wheels with no reports of things being broken. In theory you could get the rear beam axle from an xD to get 5x100 in the rear, but I don't know if anyone has attempted that.

You don't need to swap the whole axle, just the hubs/bearings and I would imagine the xd drum setup. Unless you redrill the yaris drum to 5 bolt.

During my swap I spent a bit of time comparing hubs/bearings. Seems to me everything fits everywhere. Xd to Yaris, Yaris to Yaris se, Yaris se to xd... It all bolts up. You just have to match your brakes to your lug setup.

If you're going 5 lug on the front, you'll need xd rotors/calipers or redrill the 4 lug rotors.

4 lug on the front, stock Yaris brakes or Yaris se big brakes

5 lug on the rear, xd drums or redrill Yaris drums to
4x100.

However I have not yet checked ebrake cable compatibility between Yaris drums and xd drums. I would imagine the brake line is compatible.

As for the se rear disks, we know there is different lines and ebrake cables for the calipers

I chose to stay 4 bolt on the front so it matches my rear disk brake axle. As far as I know, I can't convert the rear disk brakes to a 5 lug setup using off the shelf parts.

the whole xd rear drum assembly including the 5lug hub should fit. yaris and xd share the same axle beam. the xd drum is larger than the yaris.

The xd drum wheel bearing/hub does bolt up to the Yaris axle. That's a fact. I did it myself. Only thing I don't know as of yet is if the ebrake cable and brake likne from the Yaris fit on the xd drum.
