Question about T25 vs. T28 turbo - Toyota Yaris Forums

kou · 10-24-2014, 05:46 PM

We have a low redline and good torque stock you want to try and emulate that with your turbo setup. This engine was not designed for high revs as much as it was for low down torque for a 1.5l its build is robust the cylinder walls are as thick as the 2.4l in the TC and they hold boost well.
When searching for turbos its hard to find info for our application because nearly every other car revs 2-3k more and are moving more air and need something that breathes a lot up top.
I very rarely go to redline as now I am not searching for power(also have stock motor and clutch 130K miles which will change soon) because between 2500-3000rpm the power is in any gear.
