TC swap?

Very different engine characteristics, the 2ZZ needs to rev HARD to get its power, while a larger engine would be much more torquey and usable.

PK, if it's the latest model MR2 then yes, that would be a 1ZZ engine. Engine which was also used in the previous generation regular 1.8L Corollas. The 2ZZ (Celica, Matrix/Corolla XRS) is essentially the same engine, but with the VVTL-i head which, like Honda's VTEC, allows a high-RPM cam profile for an increase in power, like a second wind, if you will... These engines have been swapped in Yarii over here, as well as Puerto Rico, and I am sure in many other places.

If it's an older MR2 then you'd have the 2.0L 3S-GE engine, a very very respectable powerplant but far larger and heavier than the ZZ series. I have seen one with my own eyes wedged in a previous-generation Vios here, really tight fit!

Sounds like I need to revamp the old "motor swap thread"
2az (New TC 2.4L Motor) Will not fit.

Reasons why,
1. Its a BIG motor compared to the Yaris motor, I mean yes it is small in comparrison to other 2.4L motors, but it is fairly too big to fit in the tiny Hatchback engine bay, even the sedan engine bay wouldnt hold that much.

2. The complete orientation of the motor is reversed from the Yaris, meaning that the hot side (exhaust) and cold side (intake) are reversed...This will only complicate things if you want to keep the ECU and cooling parts in their same area, IF you wedge the motor in the car, but the header is 3 centimeters from the radiator, your going to have a small issue. Or if its 3 centimeters from the ECU, problems once more. The hardest part of this particular swap, would be rebuilding the engine bay from the ground up to make everything fit and work in a harmonous manner. Plus there is the downfall of having to change either the complete setup of the engine bay, or the orientation of the motor...CUSTOM WORK, of course your going to expect it when it comes to exhaust and intake piping, but when you have to change drivetrain parts, who says that the TC transmission is even going to come close to fitting, and if even clear certain critical parts of the Yaris. Then your going to have to pray that after all this, you can bolt up to the origional driveshafts, if not...more custom and costly work.

3. IF you were to swap this in, there are better and smaller motors out there that can generate the same if not more HP than this engine. The 2az TC motor only produces about 160hp, the Xb version even less...Now compare that to a 1zz from the Celica (140hp) add intake, exhaust, header, pulleys and you are at the same HP level. Cram a 2zz in there and your looking at 170ish HP. A 4age Blacktop is around the same HP as the 2az. I am not saying the 2az is a bad motor, just there are more motors out there, than just the TC one.

4. Money, IF you are willing to spend this kind of money into a car, I would assume that more than likely you could have afforded a nicer/faster car. If you wanted 160hp to start, why not buy a last gen Civic SI hatch (Not trying to promote Honda, but just being honest).

5. With money comes another idea, instead of tearing apart EVERYTHING in hope that you can start new, take the existing motor, redo internals and try boost. Almost every application using a turbocharger out there is putting down 150WHP (WHEEL, not base), which is about 170bhp. I am not claiming that the 1nz (Yaris motor) is the best canidate for the forced induction market, but by no means does it have no potential...Just ask Garm


Oh and to clear up the cost of a 2az motor, cheapest one I found was $1100, no transmission, no ECU, no wiring harness, etc...cheapest with all that was about $2000, but with a 4spd auto, "Complete".

Oh, and heres the application list for all vehicles that have a 2azfe in them...
Most common application is the TC, and Camry
Toyota Camry (2002-2009)
Toyota Matrix XRS/Pontiac Vibe (2009-)
Toyota Corolla XRS (2009-)
Toyota Camry Solara (2004-)
Toyota RAV4 (2006-2008)
Toyota Highlander/Kluger (2001-2003)
Toyota Estima / Toyota Previa / Toyota Tarago
Toyota Alphard
Toyota Blade
Scion tC
Scion xB (2008-)

yes, it needs to be added, any swap for any engine is always possible, just requires varying amounts of skill, time and money (usually the latter).

Mike, go watch Monster Garage to get in the mood

And yes, the 2AZ has pretty good aftermarket support thanks to the tC...

I would love to do a 3S-GTE swap. thoes motors are extremely stout and i'd be willing to go as far as saying they are better then the 2JZ. Might even be the best toyota 4-6 cylinder engine toyota ever produced.

[eTiMaGo]

Doesn't Top Secret or some other badass Japanese tuning brand have a 3S-GTE powered Supra?

[turboecho2005]

yes they do ;)

Then again if money were no object then a 7age (7afe with a 20valve head and offset crank) would be the way to go. Stroke it to 2.0 and you have a very nice motor.

[Sabretooth]

the concept is, whats the most na horses you can pull?

with all the lack of space, boosting the car would not be much of a choice.

[eTiMaGo]

once again, the wallet's the limit... Most legendary would be those 11,000RPM 4A-GE's that can get what, 250hp out of a 1.6L engine?

[Sabretooth]

+1 to that...

A 8,000 RPM 170whp motor would be plenty to get this car around corners

That is why the top of my list is a 4age blacktop, with a 6spd lsd tranny...

It will have plenty of room in the engine bay of a hatch, plenty of upgrades for getting to get even up to 190ish whp with a flash and tune.

Imagine a 190whp Yaris whipping around a corner with a stiff set of coilovers, just blowing past a car that costs double and has double the horses of a stock Yaris...pure magic to my imagination.

I wouldn't say there is plenty of room... infact the 4age blacktop with the 6 speed transmission wont' fit between the stock frame rails... its a very tight fit.

[Sabretooth]

Question is, will it fit in a 07 Yaris or newer? I know that yours was crammed into an Echo hatch, so I am unaware of the possible structural differences between the two. But my gut would say if it doesnt work on the old, more than likely it will not work on the new.

Just keeping in mind if it to be a AutoX car only, only real gears needed are 1 and 2

[Yarito]

Here in Puerto Rico there is a Yaris HB that swap the engine by one of a corolla XRS. I thinks is a 2AZ dual vvt-i. 160Hp in a HatchBack?! Thats insane

[Sabretooth]

You see the original XRS/TRD Corolla featured the 2zz-ge which was the same motor placed in the Celica GT-S and Matrix XRS... It would be possible to place the 1.8L 2zz in the HB, but I am still unconvinced that the 2az is small enough or compact enough to it inside the tiny Hatchback engine bay.

Not trying to be a dick, but I personally would like to have either some photo evidence, followed up with a video of it running. Anything to prove that it would be plausable

Compression ratio: 9.0:1 or 12.3:1!!! That would be a NASTY all-motor Yaris!

once i pay off the yaris and pick up a cheap beater car to become my new DD i'm swapping in a built 2ZZ, with turbo. i decided this just now. cali will be dethroned for having the most bad ass yaris. its just not happening anytime soon. hahaha

[turboecho2005]

mid engine RWD 3sgte setup in a yaris.... that would be the ultimate....

maybe i should buy a yaris just to do this swap! the 2006 used cars are getting cheap.

[Sabretooth]

Fun stuff!

[Sabretooth]

My dream Yaris is cramming an STI motor in this car, then changing from FWD to AWD.
