Lpg?
Just wondered... what of LPG? It's becoming very popular round here.
Is there any special problems with converting rotary engines... and what of the ECU? Does it need to be remapped or not?
Don't think I'd do it... at least not right away, but it's somthing to think about anyway.

Liquid Petrolium Gas... Basiclly propane...
Is sold along with Petrol and Diesel in a growing number of filling stations here... somthing like 30% now. It's less than half the price of unleaded and conversions are about Ł1000... you retain your regular fuel tank and gain an additional LPG tank and a switch on the dash...
Most petrol cars can be converted with a fairly simple kit, and most don't even need an ECU change as far as I know..... You get 90-95% performance for less than half the cost... My Landrover 110 3.5 Litre V8 costs about the same to run on LPG as a petrol car that does 40Mpg...
All the american car clubs here do conversions, especially V8 trucks... because it's so much cheaper.
I just wondered if there was any special issues with the rotary...

Propane is actually very well suited to a rotary, especially if turbocharged. Oh, and if you live in California, it doesn't even require a cat because there are very few emissions. It's perfect!

OK so just for fun I want to revive this thread and see were we are at 7 years later.
Here what I found and it looks interesting. But I am still learning on the difference between a rotary and a piston engines.
So lets hear everyones input.

So I have done a little more research and it looks like with our cars. If you drive only 30 miles a day, It would take more than a year to recover the cost of putting the conversion in your car.
But I also read that with LP it give you a octane of 110 and release no carbon into the combustion chamber when burned. So it should produce more HP.
Any thoughts?

^well there would be no need for 110 octane unless we're running crazy amounts of boost! however the NO CARBON idea I like alot...maybe this would be a breakthrough to bring the reliability up for the rotary...
My opinion would be that if I could get 300k or more miles out of my motor with LP then even me driving about 20 miles a day at least if would be worth it because that fact that I could keep my car for 10 yrs and not have to worry about it....same aspect of a diesel most ppl that buy those new keep them for 250k or more and can easily go 500k on the motor!
Maybe thisin the 16x from the factory? haha

Seems interesting
Edit:
Looking at other cars' setups.. I don't know where the heck you could fit the giant explosive tanks in an RX8..

Well a 40 lb tank would fit under the rear deck in the trunk. It is the equivalent to 10 gallons.
I have also read that there is anywhere from zero lost in mpg to 10%.
LP is selling for about $1.30 per gallon.
On a 13 gallon fill up that is about $1.60 per gallon savings. If you use 13 gallons per week you save $20.80 a week. Times that by 52 weeks a year and you get a savings of $1081.60
So it would take about a year and half to recover the invesment of the set up to go to an LP bi-fuel system.

Also, gas near me is $3.09 now, so that's about twice as much the cost of LP for me =\

^yeah unfortunately gas is on the rise again....i was liking it around the 2 dollar mark....A yr and a half to pay for the system wouldn't b bad at all.....I mean half the price of gas I use about 50 bucks a week or so in gas so that's be about 25 a week...I'd b happy with that!

Remember
I think it is interesting.
I don't know if I would have the guts to do it. So how putting a turbo on a car seems natural, but putting something other than gasoline in it seems strange. The only real draw back I have seen is there is not an LP station on every corner to fill up at. To always save money.

Well remember this is a bi-fuel system so you could run gas every once in a while and LP the other times.

what about these guys from UK ( http://www.egasuk.com/rx8.html ) look what they say:
"although all the LPG components appear to be standard, there are some real differences we'd like to keep to ourselves for now"
anyone know someone with a kit for these EGASUK guys ?
