Yaris Motor Swap Thread *Read before posting swap threads*

[Sabretooth]

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.

i know why they are in a "why?!?!" section, but how come those specific ones are mentioned? just because of smaller size? i wish i could put in a wankel.

how about a busa?
1340 cc (82 cu in), 4-stroke, four-cylinder, liquid-cooled, DOHC, 16-valve

x2

It has been done it the Smart, so why not in our cars ? Would be nice.

The 3S-GTE engine is also found in celicas(GT4 = AWD) Doing a full custom AWD/3sgte swap from a celica GT4 to a yaris would pretty much be my dream swap.

The only problem is, that is one huge engine to squeeze into the yaris.

the 3s weighs like 360+lbs... thats an extra 200lbs from the 1nz

what about a 4efte instead??

This is my dream too my friend...And i done it...........

[at3GG]

i think the sr20 should be a distant consideration as well...

[xbalance]

Is there any engine is a direct fit to the engine bay mean dont need to mod the engine mounting location?

[at3GG]

highly doubt it

[eTiMaGo]

in theory the 1.8L 2ZR-FE from the European-spec Yaris TS (and also the same engine as used on the new Corolla and Scion xD), as I highly doubt Toyota would have two totally different bodies for each engine. But, with "just" 130hp, it's not exactly worth the swap... unless it can be built up to much much higher levels, but I don't think that has been proven yet....

Looks like this has been confirmed and well documented:

What would be needed in order to do a b18c or k20 swap?
I like the idea of having a honda engine with a LSD transmission.

First, ditch the B-series. It spins the wrong direction. K-series spin the correct direction.

Buy a donor K-series. My suggestion is a cheap Base RSX, Ep3, Element, or CRV. You'd be best off with the 02-03 Ep3 as their axles are smaller and fit 4x100 spindles so should be easier to adapt, not to mention their wiring harness is easy to use and adapt. If you need a Helms service manual for wiring, have it in .pdf form,

1. Custom motor and transmission mounts
2. Pre 2000 Honda aluminum half radiator
3. Donor K-series car (for engine, tranny, wiring, immobilizer, matching ecu)
4. K-tuned or other aftermarket shifter box and cables for easy floor mount.
5. Cable operated and modified throttle pedal OR a donor drive by wire ecu and wiring to adapt to the Yaris.
6. Kpro for a drive by wire application OR a 02-04 CRV, 02-05 Ep3, or 02-06 RSX for cable operated throttle.
7. Spindles and strut adaptation from the donor OR custom axles for the Yaris spindles.
8. PATIENCE, MONEY, AND TIME.

If you insist on boost a K20a3 is the cheapest swap and can handle 300whp for s VERY LONG TIME, but one the torque gets over 300wtq k20a3s have a tendency to bend rods. K20a2, K24a2, K24a2, K24a4, K20z1, K20z3, and K20a (02-06 ITR or JDM Ep3R) can all handle LOTS power with the only problem being compression and detonation risk on the higher compression K20a2, K20z1, K20z3, and the K20a (11.5:1).

I'm sure I'm forgetting things. This is just off the top of my head stuff as a Moderator of Ephatch.com.

1. take 1.5L out
2. put built/stroked 1.6L in
3. turn up the boost... a lot.
4. have a nice day.

[dallas]

Only if you run a sucessful online Tuner business and spend all your hard earned cash on your Yaris
