I noe the 99-04 ones work better with CNG, but there are some issues involved in it, but due to the fact i wont get a better car after selling my Vitz. my only choice would be a Alto that too i would have to put in money.
So i am taking a risk getting it cngfied, (thats the only option) if CNG gives me 12-15kms a kilo for Rs.50 a kilo, il start saving, iwas geting 17kms a kilo on my Baleno.
Petrol now gives me about 10-12kms a kilo, for 80 a liter
keeping in mind the cars running for 10-20kms daily has rose upto 80kms a day.
Now all im concerned about it the what kit/advancer/emulator to use.
@rawfay, im considering the 50kg cylinder due to the weight factor. Altho had a 60kg in my khyber worked fine.
