Yes, CNG can be installed in a Turbo car using Lambda Sensor Kit with MAP/MAF. It runs just fine.
And CNG runs gr8 on Vitz too with Lamda Kit CNG.
The better option will be a Vitz because of the following Reasons :
- Better Parts Availability
- Parts are Cheaper
- Lesser Amount of Tuning Required (as compared to Terios Kid)
- A little better Resale
- Better Looks
- More Fuel Efficient
