12a N/A LPG ??

[shaunwil]

Im seriously thinking of buying the 1st gen Alan is looking at selling and will be wanting to convert it to LPG and use as a daily driver. Im been trawling the web trying to find some info but am coming up a little blank.

I\'ve found this : http://autospeed.drive.com.au/cms/article.html?&A=0406 and it shows that it can be done (even grinder may be interested in it) which has a turbo\'d 13b in a 1st gen running solely on gas.

I\'ve found http://www.gasresearch.com.au/ where the bits for that car came from and i\'ve sent an email off to them asking about the 12a

Has anybody else ever thought about doing it to a 1st gen N/A ?

Cheers

Hi Shaun,

Don\'t know if you\'ve seen this on e-bay:
http://cgi.ebay.co.uk/1989-MAZDA-RX7-2-RED-Rotary-Wankel_W0QQitemZ110034775326QQihZ001QQcategoryZ18211QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

They\'re pretty local and might be able to give advice, although I\'d assume it would be an injection conversion.

Nice find :Thumbs-up I\'ve sent him a message to find out if they do conversions.

the thaught of LPG and rotaries has never filled me with great confidence....

Much like a two stroke a small proportion of the lubrication of the seals comes from the fuel itself, and due to the combustion chamber design, cold quench characteristics and firing of the rotary they need a LOT of fuel to run....

This being the case, take away the lubricating fuel and you are inevitably going to encounter problems.....maybe just up the oil injector sizes?

Ive seen reciprocating engines fail after 3 years use on LPG when the valves receed too far into the head.....Just be carefull is all im saying!

The article in autospeed was a very interesting read, they had been using ot for years and had got 160k km so it must make alot of sense. They run it purely on lpg.

Im going to do some serious digging !!!!!

Went to look at the car today (200 mile round trip) an it is a very solid car that needs a few minor jobs to it to make it a daily driver.

[shaunwil]

Why never If it means i can own one and use it every day

You can run a lil 12A carby for a daily !!!!!!!!!!!!!!:spank :Typing :evillaugh

I\'ve done a bit of digging and i think im going to go for a gas research carb and B2 converter. Not sure if I\'ll have to get them imported. Plus i\'ll get pip at WGT to tune the car if it all comes to fruition.

I can remove all the emissions stuff off the car too so i should be able to put a quieter exhaust on it (wanted to be a daily driver).

The dryness of lpg is quite a heated topic on ausrotary ! Anyway if i blow the engine up it won\'t be silly cost to replace or rebuild (with porting)

Has to be cheap though !!!!! Aiming to cost about max 15 quid a week for about 150miles !!!

^^^^^ ha ha ha, where do you get these pictures Era? That must be one of those Holy Bongs, :rollin

A 12a running twin SU carbs is supposed to be quite efficient!!!.... Maybe worth considering in the quest for more MPGs... Cheap too. You have to consider the cost of an LPG conversion, cant imagine its gonna be cheap, are you really going to pay of the cost of the conversion and as Era said, it won\'t run the same. Interesting project though, maybe you are onto something.

The plan at the minute is to try and get it running completely on gas and get about 20mpg on normal day to day running. Looking on ausrotary it is pretty possible, hell they do it to turbo\'d cars.

I drove a 1st gen yesturday and its absolutely nothing like a diesel, my pug is soooooo guttless !

Im looking more for info than banter, but the picture is funny !

Oh and im planning on doing the fitting myself so i think the budget is max of about 700 quid, but then i have the bits for another car in the future.
