1.3 on 33's" you def need to lower the gearing. 410 t box is a start, would be better with a rocklobster (super low geared t box), or change the diffs for diff ratio's.

As Jordi said there's not much you can do with the 1.3 power gain wise

There's loads you can do to the 1.3 if you want to spend money and ship it over from the US. There's probably more available for the 1.3 than the 1.6. Cams, hi-compression 10.5:1 pistons etc.

Stick quad gsxr carbs on a stock 1.3 and you can get more power and torque than a 1.6.

Now that sounds very interesting Scottiej do yo have any more info on that conversion.
