Don't do It!

A friend of mine had his LS 430 converted to LPG His car was sluggish thereafter and, after a couple of months the air filter compartment blew up into a thousand pieces.

Think long and hard Pal

 

I do not believe you will ever find a natural gas conversion kit. A Liquid Propane conversion might be possible, however this would be a custom setup, that you would pay real big for. I can't imagin the costs of the kit would outweigh keeping the car the way it is now.

LPG makes no sense as it is a petroleum product and there is no savings
i am looking for a conversion like the Honda Civic

 

I was under the impression the propane injection was reserved for desiel motors only?

 

Every country in asia and many is europe do it. It is safe and much much cheaper. Utah has NG refill stations for such vehicles. Google it and you will find that many people are converting to a combined system. No one has blown up yet.
