Yaris Motor Swap Thread *Read before posting swap threads*

Well, I lost the old thread back in the hack, so finally got around to wanting to redo the thread, hope you enjoy. Hopefully it will sticky this time

First lets start with catagorizing particular motors that have been tested, proven, and thought about being swapped into our Yaris'

Proven: This is the basic section in which a motor has been swapped and documented to work.
-2zzge (Celica GT-S Motor,1.8L 180ish HP) Proven Sedan, and older gen Echo Hatch only.
-4age Blacktop/Silvertop (1.6L 160hp) Proven swapped into an older gen Echo Hatch only
-4agze 16 valve (1.6L Superchared) Proven swapped into a newer Yaris, overseas, but documented. Motor was then changed over to a turbocharged setup for more HP.
-DRIFT YARIS: I dont have information off hand, other than it is a RWD placement using an older Tacoma motor for the powerplant, All custom drivetrain, etc.

Tested: Experimeted, but not finished or proven
-4G63 (Lancer Evolution Motor, 2.0L Turbocharged) Swap was to be in progress but not documented as finished overseas.

Thought of and Discussed: Self explanitory, I did seperate this into two catagories.
Practicle, but likely not to fit without heavy modification.
-3gste (MR2 Turbocharged Motor) 2.0L Turbo
-3gse (MR2 Beams Motor) 2.0L N/A
-2azfe (Scion TC/Scion Xb2.0 Motor) 2.4L N/A

WHY?!?!
-K20 (Civic SI/RSX Motor) 2.0L N/A
-B18 (Civic Motor) 1.8L N/A
-B16 (Civic Motor) 1.6L N/A
-13B (RX7 Motor) 1.3L N/A or Turbocharged
-Renesis (RX8 Motor) 1.3L N/A

Ok, lets get down to business:

1. Motor Swap intro
With all motor swaps, there are two things your going to need: Time and Money, without both; your project is dead in the water before it stands. Motor swaps are not an overnight deal, you can just wrench it up in a weekend for a car like ours. There is a lot of time taken into changing wiring harnesses, coverting throttle types, custom piping for exhaust and intake systems, then there is modification to any structure of the car (firewall, etc), not to mention any custom parts you might need to order, or fabricate. If you dont have a second car, I wouldnt expect you to try and do this without having another form of getting around for 3-4 weeks, depending on who is doing the job and how much time is being invested daily.

Money is a precious thing when it comes to a swap, if you dont do it right...you could be left with a car that looks new, but runs like a clunker. All used motors need to be broken down, inspected, tested, and cleared by the mechanic or installer to see if there are any major issues that need to be fixed or addressed before the motor you just spent up to $4000 is placed into your car. Not just are the engines costly, a 4age can run you $800 bucks for a good mileage one. A 2zzge can run you almost $4000 for transmission and all, best bet is to check before you buy. Sometimes you can find just as much horsepower in a smaller, or cheaper engine.

Money is also another factor when it comes to installing the motor, when you start working, nothing is going to just bolt right up and wire in. You are NOT working on a Honda, so be prepared to start cutting, splicing, etc. That you will be more than likely fabricating new parts or modifying existing ones to make them work. This can take both time and money, depending what you are having done. Custom driveshafts could take a week, seeing where they are being sourced or made from. Nothing is going to be easy, even a experienced mechanic will let you know this one when it comes to doing a new Toyota swap.

You can only expect one thing, lots of time and money leaving you, totaling into the weeks and possibly months, and up into the $5-6k range, depending on cost of parts and labor. This number could reach into the $10k+ range, also pending you are going to further modify the engine before or after install.

2.Basic already known knowledge about swaps for the Yaris

From a personal aspect, I will include one thing, IF you are going to modify the engine of in which you are placing into the car, please do so BEFORE putting it in the Yaris, say if you change an intake manifold after you put it in the car, it might not work anymore...this problem could have been addressed and fixed prior to install.

So far we know a bit about doing swaps for the Yaris, there are basically a couple people who have gone in depth to check into, or swap out a motor themselves. So far only 1 motor swap has been done in the US, rest are from Canada, Puerto Rico, and Thailand, others may apply...depending on sources.

So far the only information we have on parts that bolt up with Yaris parts from other motors:
-Throttle bodies from 1zzge motors will work on a Yaris, but throws a CEL unless modified.
-Transmission parts from the Xa/Xb/Echo will work on a Yaris, consult previous threads for more information on specific parts.
-RUMOR: That a 4age series motor has the same transmission housing as the Yaris, I have yet to find supporting information to confirm this, but it has been spread around enough to be considered possible.
