LPG on a turbo Forester?

[rovermorris999]

I'm shortly looking at a 2001 Forester Turbo auto with a genuine 35k which has a professionally fitted Prins multi-point lpg system fitted. Now I'm not interested in the pros and cons of lpg in general, I've made my own mind up on that, but I've not had or known anyone with a turbo engine that's been converted. Are there any potential problems over a n/a car? Subaru will do a similar conversion from new (or did until recently) so I'm assuming there are no problems but does anyone know any better?
