    Default CNG in Toyota SURF

    Hi PWs,


    Owing to the ever increasing fuel prices I plan to install a CNG kit in my Toyota Surf with a 3RZ-FE (2700 CC) gasoline engine. I had a couple of questions which I hope someone could answer.


    Which is a suitable kit for such an engine?


    What is the optimal cylinder size and where it should be positioned?


    How is the performance and fuel economy with CNG and is the mod worth any cost savings?


    Thanx
    Life is not measured by the breaths we take,but by the moments that take our breath away.

    Installation: you can get away with a 55-60 tank but don't expect to go far if you put your foot don a few times. you're better off fitting a multi tank setup by removing the spare tyre and using the space for 2-3 small tanks (approx 15). This will decrease your range dramaticall BUT you will be able to use the boot space and your vehicle will not suffer the burden of carrying excesive weight (3 small tanks are only a little heavier than a spare tyre so no mods will need to be done to the suspension).

    Economy: not much benefit of you drive it less than 50-75km a day.

    Performance: not much difference if you have it tuned correctly (for performance) but you will lose alot of range. however if you have it tuned for range than you will have pathetic performance (it will behave as if it has a 1.6L engine)

Never argue with an idiot, they will bring you down to their level & beat you with experience, 5. Growing old beats the alternative -- dying young! 6. انّا للہ و انّا الیہ راجعون

    Have seen cygnus and surfs on CNG in lahore. They seem to be working fine though i personally wouldnt recommend. Range will be an issue and considering how cng is being discouraged by creating a shortage and everything, you will be spending all your days in queues specially in winters.

    that's a pretty personal question. we've all seen on PakWheels how expensive cars are getting refilled with gas. i myself knew (he'd dead now) an extremely rich businessman switching his 500SEL to two cylinders of gas...............
