Yaris Motor Swap Thread *Read before posting swap threads*

[omarnas]

Hi
I have 2nz installed in my car and I would like to upgrade it to 1nz.
can these 2 engine be swaped with out the headache of electrical wiring??

[Bluevitz-rs]

Yes the two motors are the physically the same. Though I'm not sure anyone has run a 1NZ on a 2NZ ECU before.

Here is a great way to give a swap a try and it is a pretty sweet price to start:

JDM 4EFTE

Less than a grand gets you a boosted motor with great internals and potential!

[ilikerice]

That wouldnt be a direct bolt up as far as motor mounts though, correct? I am not familar with the tercel and scartet chasis and motor setups.

but for 130ish bhp, don't know if it would be worth it if you still had to fab up parts and wiring....

Personally would rather do the xD 2zr swap..

[Bluevitz-rs]

For the same power and way better fuel economy, the 2ZR is the far better option.

Personally I can't really understand why someone would even consider FE if they are going to go through the process of a full swap. THE 4E-FTE is lighter than the 2zr, has stronger rods, and a very nice compression ratio of 8.5:1. Also it has a lightened crank from the factory. This motor has the ability to easily get 38-44mpg on the highway in the Yaris paltform even om the higher boost setting for the internal wastegate. Around 32-35 in the city I bet too. Since it doesn't have all the other electronic BS required as the newer engines I have known guys that have bumped it to 1 bar of boost, kept their FE, and been around 165-175hp handily. Then if you wanted to get really into it you can get 260-300hp out od it without even changing the internals. You won't do that I don't believe with the 2zr.

The 4e-fte was direct from Toyota with forged internals. Very easy to make a lot more out of it and less of the electronic control and bullshit of today's engines. Yeah, you would need a little bit of fab work, but would be interesting I think.

Stock motor vs stock motor.

If I am going thru all the trouble of doing a swap like that (fab mounts, fab wiring for ecu, fab axles/hubs, shift linkages, pedals for throttle cable), I would go with a 2zz motor. Stock vs stock. and even then the supercharger for the 2zz has alot of aftermarket parts for it, from the lotus, that are reliable upgrades.

I would like to do a 2zz swap, but I think the 2zr is going to be the best I can do since its been done and a fairly good write up on it on MicroImage website. That is if I do end up doing a swap. But the 1nz is a good platform as well to do a turbo as Garms old Yaris has shown us. As well as Blown xA and a couple other here who boost the crap out of thier 1nz. I think the only real issue with the yaris is the ecu. Damn thing is like a steel trap and is smart as f*ck

The 2ZR is being developed for the Lotus Elise, supercharger and all. I'm also entertaining pipe dreams of a 2ZR swap followed by a Blitz mod. Lots involved in that one.

That said, a 2ZR spec sheet I found lists a 0-60 mph time comparable to my 1NZ + Blitz, so it's more or less the same benefit.

I hear ya rice. I just think that it would be cool if someone did the 4e-fte swap showing another real option. I had considered the 2zz a long time ago then dismissed it because of the extra couple hundred pounds it it could end up being on thw front suspension. If you do the 2zr just make sure it is from the xD and not the previous years sin e there is the documented oil consumption issues. Yes the 1nz is a very capable engine, but as many have noted a pretty expensive one. Just a harness, switch to MAP, and full standalone is over 2k and I speak from experience.

Aren't you going to run into that issue with any Toyota engine? I don't think any Toyota OBD2 engine has great tuning support outside of the trucks.

I'm stuck dealing with OBD1 tuning issues on a Miata, and I just can't see why you would want that. OBD2/CAN is great from a tuning, and diagnostic standpoint.

Thomas has an OBDI 4ag and doesn’t seem to be having any problems. The beauty with the 4e-fte is that it gives you options down the line since it has beffier rods stock and a great compression ratio stock as well.

Agreed, definitely a viable option compared to some. thanks for the tip on the xD. Agreed on the weight of the 2zz, but that stock rev limiter... I wants!

In a year or 2, never knwo what may drop in my lap. May come across a wrecked xD or Celica gts... I am rebuilding a 4age motor, but I don't think I wanna go that old school in a yaris.

[CrankyOldMan]

Disregard, the 2ZR-GE supercharger is only available directly from Lotus in the UK. The only way to get one would be to buy it from them (assuming they would even do that) and then get standalone management. I already own the Blitz, and am not afraid of making my own conversion parts to get it on a 2ZR.

Bah, you don't really want to come play in SMF. The PAX modifier is murder on our little cars. =P
