Yaris Motor Swap Thread *Read before posting swap threads*

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.
