I used to own 1.6cc CBU Auto Getz way back in 2005. Mods done were:-

1. K&N drop in air filter(better FC)
2. Extractor kit with full pipeing and Sflow exhaust (some slight increase in power)
3. 16"rims with Falken tyres (looks nice)
4. ICE(better sound lorrr)

All else was standard, no BKits...car lasted 1 year, sold and bought something else
