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?

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.
