I need it, how much?

A complete Nitrous Oxide DIY kit, complete with bottle, solenoids, wide open throttle switch, arming switch pipework and fittings will set you back Ł574.58inclusive.
This is suberb for the performance and pose factor available and is infinately more cost effective than major engine work like cams, turbos, porting and ECU chips (Klik for examples of 10bhp Superchips @ nearly Ł300!). Even exhausts are expensive and although they sound great, do they actually give you more power?
This table compares popular methods of performance tuning and gives a breakdown of how much HP/£ you actually get for you money (based on a Maxda MX-5).
