As they quote... "The 1.6L development reached 241bhp/148lbft a few years ago"
They have a great supply of engine parts and were really focused on the 1.6L for a number of years.
Now they have started to heavily develop 2.0L parts.
Here is an example of the power curve for their basic multi throttle kit... which makes 140hp close to the 8000RPM redline.
Keep in mind that they sell aftermarket engine management systems for the 1.6L..... so your not going to manage 8000 RPM with your stock ECU
