It really isn’t often that we are surprised by an outcome of an engine build, but this Corolla’s 2ZZ-GE has left us all with our jaws open. We have completely rebuilt the motor from the block up, the specs are in the image below. Using the current Haltech Sport 1000 ECU we’ve extracted an impressive 323Kw to the front wheels! On one of the earliest Dyno runs the motor was making power beyond 8,800rpm, and up to a ridiculous 9,200rpm. But to future proof the build and ensure safety we are limiting the red-line at a screaming 8,500rpm.
You’re thinking traction right..? Yup, needless to say it has traction issues, but we have a plan to help it put the power to the ground.
The next step will be to switch to a MoTeC M130 ECU. By using the drive-by-wire feature of the MoTeC we can use Torque Limiting to help traction, this process has two functioning elements to it. One ; the ECU computes the difference in wheel speed between the front and the rear wheels. Then applies ignition timing to guide the power through the drive-train. Two ; the drive-by-wire allows the ECU to over-ride the physical throttle position at the throttle body. With a combination of the two processes, the ECU computes the differences between all these factors and applies both ignition timing and throttle position to release the 323Kw to the wheels.
