Yaris Engine Swaps!!!

[turboyaris]

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.

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
