U340E is used from the 2006- yaris (all models minus the IA, to present, so It should fit with Mk2 and Mk3 models)

Haha thanks man. You should come out again and get hooked lol.

Finally got around to changing my rear springs, can't wait to test it out this weekend!

Enjoyed the install video!

So jelly of the Swifts, the thought crossed my mind when I received my Cusco Street Zeros, but figured I'd see how Cusco's springs perform. So far I'm happy with my 7k/5k set up. I also removed my trd rsb, figured I didn't need it with the 5k rear (compared to the 2.8k progressive springs).

Coming from a spring/shock combo w/ trd rsb, the car was too soft for the track for my liking, plus I was getting understeer at high speed sections, but very likely that I'm not that great of a driver, and not slowing down enough.

Car feels pretty neutral at Streets of Willow earlier this month. Big Willow is the next event, can't wait to destroy my PB!

Can't wait to see your next autox video; oversteer, windshield wiper counter of fury, and killing more cones! (jk, but it is fun! )

I considered the Cusco setup for a long time, but the overseas service was hard for me to accept. They are a great product for sure though.

So for with the BC testing we've found that it's better for autocross to have a harder spring in the rear, and aggressive damping. At the track you may want to leave the springs where they are though, safety first out there is more important.

I'm planning to hit Big willow next month with the TRD cup as well

You are correct. Since Im only working with 140hp, all of our development attention is on the suspension and driver right now. We are only 1 second behind the turbo/hoosier tire miata currently winning in prepared class. Im still leading in championship points but we need to close that gap to prove we can run this car at the Pro Solo next year and do well.

It is a lot of fun, since we only drive it at races Im surprised every time by its acceleration and cornering abilities. Its very capable of winning Prepared class as well....with the right driver.

Ultra Racing Rear Lower Brace Install

I finally got one of these rear braces for testing before we do any more spring changes.

Hi, my name is Vincent, and it’s my first time posting. I’m picking up an 09 S hatchback this week and I have a motor and ecu with wiring harness from a 10 Corolla that’s been sitting in my garage for a year and a half. What are the main reasons the electrical/wiring setup from the XD are more favorable than the Corolla’s? Could the Corolla’s components be used still, or would the amount of wiring make it unfeasable?
I’m excited to do this swap, and I’d like to use what I already have. Any help would be appreciated!

Hey Vincent, welcome! If that's Woodstock ON you're not too far down the road from me..

One of the folks who have completed the swap with the xD harness can elaborate, but basically the xD is the most straight forward because the Yaris and xD share the same platform so everything is plug n' play - install the xD ECU in place of the Yaris ECU, xD engine harness runs to stock ECU location and connects to Yaris body harness, etc.. I'm not familiar with the 2010 Corolla wiring and locations, but I imagine you're in the same boat I am with the Scion (now Corolla) iM harness - will need some changes and relocation of the ECU. I can tell you if it works in the new year, lol.

Lots of good reading and awesome folks here on YW. When you dive into it get a build thread going and document your progress.

Pretty much what Adam said. The xd shares the same chassis to the yaris so when running an xd ecu and wire harness it is virtually plug and play. With the exception of having to add 12v ignition power to the maf and taking one connector and wires from the yaris wiring harness for the speedometer (iirc).

If you end up going with a corolla harness and ecu then you have to get a wiring digram of the corolla and yaris ecu and figure out what wires and connectors you need to repin so that everything works properly on the yaris chassis side of things.

With an engine swap the tough part isn't just getting the engine to run via an ecu, it is trying to ensure everything in the car is still working that goes along with the engine

Imo if the yaris is your second car then go ahead and take the time to re wire it. If itnisnyour only car and/or dd then source a used xd ecu online and either do the same with an xd harness or just foot the bill and order an oem one. The big challenge with this swap is finding the xd harness and ecu for a manual transmission in the used aftermarket so you don't have to pay out the a*s for a new one
