Hi there I did some research and took the advice from this thread and gave Phil price a call I have now had my rx400h 2006 converted to lpg all I can say is absolutely brilliant I left my car with him for a week this gives him time to do a proper job and check everything is fine he really knows what he's doing and his workmanship is spot on Phil runs a rally school and all his subarus are lpg converted
The car runs fantastic its 125 miles to his place. From me well worth it when I drove home after picking up the car I filled the lpg tank up
And I had only used £13 and I wasn't hanging about either it's the neatest work I've seen on a conversion yet well pleased and would highly recommend him
