Theres nowt better value than getting Pumabuild to do a 1.7 conversion

Its 25%more power but its the way it drives that makes the 1.7 so good, with the VCT it really breathes better at the top end and feels really good. A better base for tuning too as the 1.6 has nowt going for it really. If you're happy at 120bhp-ish a panel filter, nice exhaust and manifold and a livemap or a bluefin will see that no bother, maybe a bit more but it wont feel like the 1.7.
