I have a Volvo S80 2.4 20V (2000) Now I would like to upgrade to autogas. However, there are fewer suppliers (Switzerland), but I should prefer to do the conversion in Switzerland (because of Tuff, etc). However, when I switch to this system: POWERED 5 ZyL. SLY INJECTION (120 – 140 KW) It costs somehow little, not much more than 2000 Euro. Either the conversion in Switzerland is cheaper, or I have definitely chosen the wrong system. On http://www.autogas-suiss e.ch/Price [email protected] are the other products. Maybe you recommend another product for my Volvo.
