I wish you well with this project and will be following this with interest.
A couple of questions if I may:
1. Where did you get the kit?
2. How much?
With the price of petrol now, I am seriously thinking of having a go at such a project myself.
the like that JamesV6 has posted iss the kit i have bought, remember that is only the front end though, you will need a back end kit on top of that
i spoke to the guy direct rather than going through ebay, for everything (front end kit, 70l cylinder tank, fitting kits and software) it was £700
Factor in another £100 at the most for certification and possibly 10 hours of my own time and i have made a saving over the fully installed price, granted i don't get a warranty on fitting, but i know the quality of the work that has gone ito the conversion.
I have been chatting to the guy, i have no doubt that if an order was placed by a few people for the same kit he would do something to 'sweeten the deal' if only the P&P (£35)
