Yaris Engine Swaps!!!

[Snake]

the motor you guys have in your yaris just doesnt have the capabilities to produce the power you want, dont waste too much on the 1.5
I doubt anyone can push over 185 hp with a good amount of boost

if your looking into a 2zz swap, im sure its not going to be too difficult

you can buy a used 2zz from a toyota matrix, celica gts, or vibe gt
they come pretty cheap, the one i bought for the mr2 cost me 450

im looking into if our c50 trans will work with the 2zz motor, if people can post some pics of the c50 trans then this will help

as for engine management, you can run a hydra stand alone for the 2zz

if you want to run close to stock, you can swap the yaris computer for a celica gts computer if thats possible, i know they do it on the mr2's with a special wiring setup someone designed from the spyder forums
a similar setup can be made

if anyone is serious about doing this swap, i believe it is very possible and a little bit more research has to be done
with a built 2zz and boost, you can push over 350 fwhp, think about it?

turbo'ed 2ZZ in a Yaris... I wonder if there'll be enough space under the hood to fit all that! And you better have brakes and suspension to follow, not to mention a good LSD, with that much power to the front wheels

[Snake]

anything is possible my friend
and you have plenty of room under that hood
and an lsd shouldnt be much of a problem to install
but definately some upgraded axles

A stock 1nz-fe can only see so much boost and power before things start breaking, it was never designed to. Being an FE style engine the rods, pistons, and pretty much everything else was designed entirely for economical reasons. A BUILT 1nz as any engine can take much more punishment and with the right fuel/engine management and head/cam work it can produce serious power.

The difference is that the Matrix, Celica, and MR2 all share the 1zz-fe standard engine. The Matrix XRS, Celica GT-S, and Corolla XRS had the 2zz has a standard feature. This fact means the motor mounts, transmission linkages, etc are similar enough to justify simple changes during the assembly line. The Yaris, X series of Scion, Echo, etc never had anything available except 1nz and some 1.0/1.3 options in other places of the world.

The Celica ECU or any 2zz ecu will work with a swap as long as your able to wire up the main functions from one harness to another. This of course takes some wiring ability and perhaps the discipline to not fixing every last wire (ex: not getting all accessories to work).

The real problem is getting the mounts to line up, getting the linkage right, wiring done, exhaust system plumbed, powersteering to work, ac system to link up, etc. The ABS and restraint systems will be nearly impossible.

A 2zz is definitely possible and has been done. However, these are not Honda engine swaps that two high school kids do over a weekend and a few beers. They even make kits for those guys.

I think the Yaris crowd needs a little bit more power and more work on suspension and weight loss. You can only put down so much power with fwd and we dont have factory fender flairs. Stock SRT-4's have a chore putting down 230 at the wheels in stock trim. Much past this the game just gets silly. Sure slicks and straight lines (60mph+ as the kids do these days) are one thing but turn the wheel and try leaving an apex and your going to get walked on at some point to a rwd or awd car.

While its a fun idea to make a wild flame-spitting tire smoking Yaris but its probably not the most practical. Any Yaris that can corner flat and put down 15-16 second quarter mile times is a blisteringly fast car on any track. Remember a Cooper S only do low to high 15's stock.

Fuck it, who want to see a Chevy 350 in a Yaris!!!

This pretty much sums up my view on anything performance-related with this car.

[eTiMaGo]

Very good insight... Personally I would not want to see more than 200 hp on my car, more than that would basically go to waste, I'm not gonna go drag racing

not a bad post only thing i disagree with is this "You can only put down so much power with fwd and we dont have factory fender flairs. Stock SRT-4's have a chore putting down 230 at the wheels in stock trim."
dont know about this considering my SRT puts down over 600 fwhp, so I kind of disagree with this one.
Ive seen front wheel drive cars put down close to 1000 fwhp...
For an SRT-4 to put down 300fwhp, you only need $1500 in aftermarket mods on the motor, so its not that difficult.

If you manage to get 200 horse out of any motor at the wheels on the yaris with a good amount of weight reduction, your talking a low 13 sec hatchback thats not too bad

Yes, but what he was explaining is that it's only really good for straight line speed. If you're looking to have it go round a track, or even just daily driving that much horsepower can seriously negatively affect your handling with front wheel drive, unless you have a real feather foot.

I definitely agree with your response; it was a misunderstanding.

I re-read my post and I didnt mean "SRT-4's have a problem producing 230 hp" but rather "traction issues arise with street tires and much more than 230 whp on various tracks."

What I really should have said is: "you can only attain so much streetable horsepower before traction issues arise; FWD and street radials lowers those limits."

I love SRT-4's. They are a blast and well designed. They punish other drivers who have spent twice as much. However, many owners go the power route because its more satisfying than making a well-balanced performance car. As you have noted making TONS of power with the 2.4T is about as easy as cooking Top Ramen in the microwave.

If the Yaris had stout internals, a turbo and huge I.C., and a Quaife from the factory they would do the exact same thing.

However, I bet a Yaris with 150 whp and some little R-Compounds would be a serious toy! It might only trap 90 in the quarter but your arm wouldnt be in a sling from a track day of torque steer. Lol.


PS: Sorry for officially threadjacking the topic.

I still stand that a 2zz-ge swap would be supreme if the time or money were attainable. A solid 155-160 whp in a Yaris would be extremely fun and reliable. I would use a PowerFC or similar unit to smooth the VVTL-I curve so it wouldnt be as severe.

Otherwise for 99% of the other people I would rather suggest a very mild boost situation with an insurance fund for 1nz-fe's. One per season or a mild bottom-end build with a very safe tune.

I don't understand why anyone would want to swap in a different engine. I mean sure it can be done, but I don't see a need to unless your trying to build an ultra drag specific car. The fact that you guys are missing is that the car is a light car ~2200lbs. If you swap in a different engine you run the risk of making the car heavier, because the celica engine is going to be heavier, not to mention you have to get the motor mounts just right to keep the car from being imbalanced. Personally if you make the stock engine have 200whp you would be running a 13 flat maybe even into the 12s depending on traction, I don't see why you would need a car faster then that. That being said... if you want to swap in an engine, I would do a tc engine maybe even turbo that. Reason being is the scions and the yaris seem to have similar things in common and I know its possible to cram a tc engine in an xb so why not into a yaris. But again that engine is heavier. Keep your car light and you dont need gobs of power to be fast. Plus it wuold be cool to say you have a tiny engine and your car runs 12s. Also too about the throttle body the tc's use a electric throttle body as well so it would work. Actually the guys that have my car are looking into switching throttle bodies as a possible upgrade. I will let you guys know how it turns out.

Ah, that's the beauty of car modifications.. so many choices, so many schools of thought, so many possibilities for unique results, each with its advantages and drawbacks.

I agree in many ways.

There really isnt a reason to swap in another engine unless your running into a brick wall of performance and have money to burn. There are very very few motorsport events that allow for swapped engine vehicles and even less places you can pull it off from an emission stance. For those who have the money to burn a 2zz swap is the most plausible as all others would have to be basically assembled from the ground up.

I also completely agree that weight reduction is the name of the game. 15" wheels, stripped interiors with non-adjust race seats, etc is the easist way to make a car with 106 hp go faster. 18's and a bumpin system is only for commuters.

Sadly though a 2zz is within 20 pounds of a 1nz if not the exact same weight. I have read some comparisions on a Echo forum and you wouldnt imbalance the car at all...just pick up 55 whp.

Most Yaris models weight in the mid 2300 pound range. My 2000 MR-S tips the scales slightly under 2200 and it doesnt have side/curtain air bags or a back seat, trunk, etc.

If you could get 200 whp from a built/blown 1nz in a 2300 pound Yaris, more than likely you wouldnt get anything better than mid 13's which is still VERY fast. An Elise at 1950 with 160 whp runs mid 13's at 103-106 and most 2zz swapped MR2 Spyders at 2250 with 160 whp run high 13's at 103ish. I am sure there is someone out there with Hoosier slicks and no interior who will rip into the 12's but probably not the average. Point being, mid 13's from a Yaris is sickening fast.

From a spec standpoint the 2zz-ge and the 2az-fe are completely different animals. I know any TC fan will live and die by the performance potential of the 2.4 but compared to a 2zz IMO its not a fair comparison.

The 2zz out of the box puts out 10 more whp than the 2az, is much lighter and compact, has its powerband in the right place (due to VVTL-I cams), and internally has been designed for performance applications. Its heads and intake manifold are a work of art and its internals are stout with over 11:1 compression.

While it can be argued that the 2az has the potential to make more power (as its over half a liter larger), i believe at some point you will find flow and rev limitations as well as engine management problems. The extra torque would be great for drivability but depending on tire fitment could be a double-edge sword. Now, if you comparing a built 2az vs a stock 2zz then by all means it has an advantage. The nice thing about all FE style blocks (1zz, 2az, etc) is they are littered in economy cars making engine replacement very cheap. How hard is it to find a wrecked Corolla or Camry?

All Celica engine options, the 2zz and 1zz, are drive by wire operated so ECU wiring is the task at hand.

With stroker and boost options available to the smaller 1.8 engines (or even 1nz), IMO, its a much more viable performance option to putting in a 2.4. As we have noted, the Yaris is a very light rig and the need of all that torque isnt as great as say a TC cracking the scales at over 2900 pounds.

Still, I always invite a vehicle that has been done differently. Cookie-cutter mods are very boring and nobody draws a crowd these days with a B16 Honda swap if bone stock.

PS: Sorry Honda fans; not trying to insult anyone. Its a great engine to swap into any car...just a bit common.

somebody buy my yaris and toss a 2zz in it lol
need to get rid of this thing, come one guys help a guy out to sell a car

[mikeukrainetz]

before diving headlong into the projects im working on over winter I looked into a 2zz swap for the yaris, might even buy the parts for it if I can sell one of the other projects. Trying to find a wrecked or tired 2000+ celica, vibe or matrix around here is impossible for less than 8-9k.
From the research I did do at the time it seemed the only daunting task of the swap was the wiring. Youd need a whole donor car or engine with complete harness to pull off the swap unless you want to spend weeks chasing wires.
Only other issue is lack of front tranny mount which could easily be solved with a cross brace. Like its been said, weight is negligeable, size also, engine mounts on either side are (should) be the same. Some minor clearance issues on the passenger side pulleys and building a complete exhaust from the header back.
Nice thing is the matrix came with an AWD and six speed for a couple years, celica had a six speed in the gts didnt it? cant remember now.
I do know I took all the measurements from the AWD matrix and other than having to mock up rear suspension mounts, cutting down the driveshaft (about 4 inches to long) and putting in a tunnel it would all fit.
Course the straight engine swap is the easier of the two evils. Either way if youve never done a swap or dont intend to do it yourself it may be super daunting and overly expensive to get a shop to do it.
I for one will never spend what youd need to on the stock 1nz just to get 150 reliable hp out of it.
Ive also bounced around the idea of getting a small displacement aluminum longitudinal v8 or v6 and four link with a rear live axle from a miata so dont laugh to hard at the small block chev idea....

A guy in town here built a mini with a small block in it for the 'knox mountain hill climb' was the craziest thing ive seen, think the tranny was bolted direct to the rearend...

Anyway, dont think youll see any extreme yaris anytime soon.

[we-to-11]

Hey im lookin for the owners of this cars.... or if anybody knows owners of a yaris with another not regular engine???

I wanna get some informations before i try to put another engine in there

[slothman86]

4AGE 20v powered NCP91....ACP91 Awesome, I was thinking the same thing!

[YarisTom73]

Holy shoehorned-in, Batman... if I were to find a powerplant like that, what would I tell the junkyard to look under the hood of??
What sort or WHP would a setup like this run, with stock internals?
