For those of you who have fitted your own, mine isn't the SGI variety, it came already on the car when i bought it, what would i need to upgrade the 'front end' to gas injection and what would that cost me?
Does it use its own injectors or the petrol ones?

not really worth it. only thing you don't need is the tank. you will need new ecu, new loom and lpg injectors. not worth the investment if you already have mixer system

oh ok, thanks anyway, it was worth asking

Basically a 4 cylinder kit and remove the tank costs, possibly even the evaporator.

You'd need a complete 4 cyl front end kit. Unfortunately the vaporises are different for SGi and mixer type systems.

In reality it'd probably only set you back about £350-400 max if you're capable of DIYing it

But is it worth the expense? :-/ :-/

I beg to differ... If he's doing lots of town driving an SGiS kit will be more economical... If the current kit isn't performing particularly well it may be cheaper to start from scratch than throw money after a system which isn't ideally suited to the application. :-/ :-/

Each to their own though

current LPG kit returns around 20-23 MPG would i see any improvement from SGI. I commute to work, about 30 miles each way, five days a week, thats it. Usually put about 30-35 quid of gas in a week.

On the figures you've quoted I wouldn't expect a dramatic improvement... My 3.0 does about 320 miles between gas fills and it's a 90L tank so takes about 72 litres

No Doubt a SGI kit would be more economical, but i think the improvements would be minimal, and take a long time to recoupe the costs.
