Ok, so ignoring the fact that you are ignoring the advice from the users here about the internals of the car.

Hi, new to the thread here. I'm always looking to save money, but this statement confuses me.

So you are prepared to spend the money on the initial install, then prepared for the engine to blow (hypothetically) in 40k, then buy another one (engine itself), pay for the install, then pay again to have another system fitted to the engine? Does all this math really work out? The cheapest engine swap I found here is $3700.00 for parts and labor. You also said you believe the system will pay off in 5 months give or take, but you drive 3k/month, this means that you'll hit 40k in just over 13 months. Is this really that much cheaper?

The first sources from forum hearsay. The second is an actual source.

The installation costs 1300 USD, the car itself costed me less than 3000 dollars. I would rather count in litres than distance, since the car consumes more in the city than on the highway obviously. So the system and the car will be payed after 6000 litres as prices are now if the car runs 15l to 100km. As LoveHounds has said, the engine will wear, irrelevant of what fuel is used, so if that will be the case, I will be left with a dead engine and 3000 saved bucks for a new engine rather than a dead engine and nothing.
I don't need to fit another LPG system, I would just re-use the old manifold on which the LPG injectors are already installed and fit it to the new engine. It might need some recalibration though, but that's not a problem.

The LPG system is already installed and it runs quite well. I will post some pictures during this week.


Carbon Deposits
This is an example of a converter with carbon deposits in the ceramic catalyst. This is unusually a result of oil or antifreeze entering the exhaust system or a too-rich fuel mixture. The heavy carbon deposits clogs the converter and reduces exhaust flow. This increases backpressure and causes the entire exhaust system to heat up. The heat backs up into the engine compartment and may result in a number if heat-related engine problems.

This is what I am talking about. I can't do much about engine carbon, but I can prevent that the cat gets clogged so far that it kills my engine due to the heating up of the exhaust system.

So it's been a few months, still got a running engine?

TomX8

Actually, yes! It's still running and the savings already paid the entire installation off. In another 30.000km I will have saved enough on fuel to buy another RX-8!
