I hate all this "just wait and get a faster car" bullsh*t. Heres some options wee man:
I had a 1.4 8v 93 Clio which i did some of the following too, and it was FAST for a 1.4.
Decat, Filter (not open IK something like a BMC or something), head flowed, cam, chip (or new ECU, something like an APEXI Power FC £800 + VAT tho), larger throttle, FSE Boost Valve, Injectors, short shift (not more BHP but quicker changes so quicker acc), weight reduction, iridium tiped plugs, plug leads, a good engine flush and oil change (something like FORTE advanced formula motor flush), run on optimax all the time. There is more but thats all i can think of just now.
Lightened and balanced bottom end and better con rods (so you can raise the rev limiter), lightened fly wheel.
