colinonline Posted January 14, 2006 Share Posted January 14, 2006 Anybody have any info on the 3ltr V6 Legacy or Outback engine regarding LPG conversion, especially pin outs on the ECU etc? Link to comment Share on other sites More sharing options...
colinonline Posted January 15, 2006 Author Share Posted January 15, 2006 Thanks for your interest in this problem. The motor is a rare import in England and there is a lack of information and we are starting the conversion tomorrow and hoping things will fall into place when we get down to it. Thanks again.

Jon in CT Posted January 16, 2006 Share Posted January 16, 2006 In Europe some Subaru distributors support an LPG conversion for some Subarus. The Italian website for LPG conversion is at http://www.subarujtg.com. Good luck! Link to comment Share on other sites More sharing options...
colinonline Posted January 16, 2006 Author Share Posted January 16, 2006 Thanks you guys!! Good info. Electric diagrams will do the trick shows injector pin outs.We are fitting a AG system. Will post at the end of the project.Thanks again. Link to comment Share on other sites More sharing options...
red beast Posted January 17, 2006 Share Posted January 17, 2006 isn't it a bi-fuel car? Link to comment Share on other sites More sharing options...
Jon in CT Posted January 17, 2006 Share Posted January 17, 2006 isn't it a bi-fuel car?Sounds like it will be, soon. Subaru Germany says their system (which isn't available for the 3.0L engine) increases driving range between refueling stops to a bladder-bursting 1,000 km (621 miles). When installed by an authorized dealer, Subaru Germany's system will preserve all Subaru warranties. http://www.subaru.de/kundenservice/fluessiggas.htm Link to comment Share on other sites More sharing options...

Thanks again.What's so rare about a 3.0L engine in England? Subaru UK has been selling Outbacks and Legacys with that engine for years. Actually, there are two significant variants of the 3.0L. The older one, introduced in 2001, is known as the EZ30D and has a single exhaust outlet per head. The new one, introduced with the 2005 models, is known as the EZ30R and has three exhaust outlets per head, variable valve lift and drive-by-wire (DBW), which is also called Electronic Throttle Control (ETC). The wire diagrams provided in the post above describe the EZ30R and probably won't be helpful if you have an EZ30D. BTW, exactly which model/year/market is your rare engine from? Subaru in Japan offers a B4 CNG (Compressed Natural Gas) model, but only as a 2.0L. Natural gas is mostly methane. Methane's knock resistance is so good that it's off the scale for both Research Octane Number and Motor Octane Number (124+). Sadly, the B4 CNG engine's compression ratio is only 11.5:1, the same as the 2.0R engine's, and therefore fails to take any advantage from the additional knock resistance provided by CNG.

crash Posted January 17, 2006 Share Posted January 17, 2006 Interesting info Jon... Has any manufacturer ever tried to turbocharge a CNG engine? I assume that the fuel is still a liquid until it exits the injector, right? Link to comment Share on other sites More sharing options...

I assume that the fuel is still a liquid until it exits the injector, right?CNG (C=Compressed) is slightly different from LNG (L=Liquid). CNG can be easily produced from LNG by warming. LNG needs to be kept below -117°F. Unlike LNG, LPG (aka, Autogas) can be stored as a liquid by using only pressure. LPG is primarily propane, which has a good anti-knock index (AKI), but not nearly as good a methane. Both LPG and CNG are usually delivered to the engine as a low-pressure vapor.
