seeing as your starting with the 130PS engine you cant really do anything apart from the usual filter/exhausts, decat mods.

Removing the EGR system will free up a BHP or two and help the engine rev slightly better.

To be honnest to get any sort of really decent increase you wanna be looking at throttle bodies or carbs - or even a full on turbo conversion.

either way you need a good few grand.

There is always Nos. Its not as danderous as some people make out and doesn't fook the engine. Do plan to get it when I get a bigger engine (my 1.1 wouldn't be able to handle it :lol: )

Would cost about £700

Maybe its just me who would do that! :aviator:

As long as its set up correctly. A DIY job always runs the risk of melting a piston
