Stage 2 Turbo Project - TRD Final Drive

For the past couple of months, we have been trying very hard to get hold of the TRD final drive set for the car but with no luck so far.

I was hoping to be able to get the 3.772 final gear set so that we could increase the top speed of the car. Especially now that the car has a lot more torque, I prefer to have less gear changes by going with a taller drive ratio and highway cruising will be just sweet.

I guess lady luck has been smiling at me.

We have given up and decided to go ahead and dismantle the transmission that I bought previously from the TRD Vitz Turbo half cut to install the Quaife LSD.

The moment we cracked open the gearbox something caught our eye. The color of the final drive looks somehow different. We took a closer look at it and to our surprise, the gearbox was already fitted with a TRD final gear set!

Much to our amazement, we immediately calculated the gear ratios and it is indeed the 3.772 final gear set that I have been looking for all along!

A quick calculation with the Quaife Speed Calculator I can now cruise the highway doing 110 km/h with less than 2800 rpm.

Not too shabby eh?

Bro Mugil and Chee Soon,

And what is a super atomizing injector?

Mugil said...


its a THE injector for the water injection kit! can be used for any type of kit. Both Jack and I run coolingmist kit and CCS runs the AEM kit.
