FS: 2005 Scion xA RS2.0 Turbo - Toyota Yaris Forums

questions that I think any serious buyer would ask.

1.

Quote:

Car was dyno'd at 157WHP and 170WTQ on Stock internals, has not been dyno'd on the newly built engine.

You put in a lower compression motor and didn't retune it?
And that new motor has 6000 miles on it? This is unclear (to me).

Makes approximately 185-200WHP on 12.5psi of continuous boost.

This is a guess, right? 185 is probably low if it's built and tuned properly.

What turbo is being used? Specs?

Turbo is a Greddy TF035HL-14GK Mitsubishi turbo. This turbo Mitsubishi used on their turbo diesel Pajero line and also the same turbo used in the EDM Jeep Cherokee Diesel.

The 185-200hp is a guesstimation, I have not yet had it put on a dyno to get the actual numbers. With the current air temps here in New Hampshire it is much higher than that right now.

It has not been re-tuned at the moment. The tune I have on it now was tuned for both half and full throttle. Under full boost with the stock internals the AFR's were holding 12.5:1. On the current set-up full boost sees about 12.0:1 AFR depending on air temps so it does run slightly richer. I can very easily change my fuel trims with minor adjustments on the laptop I bought for the car for data logging and engine management.

This is with the adaptive ECU that Toyota loves to use with the 1NZFE and in the 6000 miles I have driven there has not been one DTC for a rich or lean condition on the engine or any Catalyst DTC's as well. Under cruise power at constant speed and with light throttle adjustments the engine hold the AFR between 14.5:1 and 14.8:1. And this is with the stock fuel pump and pressure regulator.

With a small adjustment to lean it out, the car would probably pull another 20hp or more out of the engine.

Conservatively, with the right adjustments the engine would make roughly 210-230whp depending on air temps.
