I suggest that you call Jameel Gill of LoGas CNG at 0322-430-3092 and get a quote from him.
I got a 2005 civic done from gasoline cng on peco rd about a 1.5 yrs ago for 41,000 (55liter faber cylinder) with an italian landi-renzo kit that included the advancer/emulator from tomasetto (you can get the argentine or chinese landi-renzo kits for less if you like). While the installation was done in an acceptable manner, I did not like the fact that I had to go back for adjustment to the fuel-air mixture 4 times after installation. The staff are good at installing but not good at maintenance/adjustment.
I ended up going to Jameel at LoGas cng (on kot lakhpat rd nr toyota township motors) and paid him 500 rs to clean and adjust my regulator and feed-line.
The service was done 3 months ago and now the car drives almost as well on cng as it does on petrol.
Best of luck with your conversion. Your car looks very nice. How much has it been driven?
