You must have more money than sence
FMIC is about £3-400
Injectors are £100 each
With that you'll need a bigger MAF - £100
Piggyback ECU - start at about £500+ and then theres mapping at £70/hour (mapping normally about £400 to get setup etc)
Bigger turbo - depends what you go for?
Exhaust £300-£600 depending on make.
...and if your wondering why the insurance is so high its cos so many get involved in single car accidents - this isnt a car I would recommend to get in to RWD motoring - they do bite!!
