Pitbull have you thought outside the box with this? when I looked into doing it for my R34 a lpg dual fuel conversion cost about £1800 and would cut my fuel bills in half, paying for itself in around 8 months. Might be something to think about as you could use manual switching to run on lpg when going back an forward to your mrs then on vpower or whatever when you want to put your foot down. Failing that I have already Pm'd you so let me know what you think
