Do-It Yourself Electronic Fuel Injectionwww.diy-efi.org/diy_efi/ http://www.diy-efi.org/gmecm/ http://www.bulltear.com/forums/ http://groups.yahoo.com/group/jyturbo It's pretty basic, you'll need to collect stuff from salvage GMs - like an engine harness / ecm harness fuel injection harness / ecm , throttle body, you'll learn about the 2 different EFi systems GM has & which one you want. biggest pita is getting the harnesses, don't cut them, you have to unplug them from the dash / fuse block etc. - then get a schematic to weed out the unwanted wires. AMC EFi IN take Manifold: MC aka 'Matt' - owner / moderator of Bulltear can modify any Alum. AMC manifold to accept injectors. Throttle bodies: you can adapt a GM throttle body to the 4bbl. manifold using an Offy 90 degree throat or mod something up - not real techie. can you do this cheap ? yeah. find a donor and you're there. save all the sensors and senders, you'll know the specifics from the above on_line forums - they'll lay it out for you. is it worth it ? sure. you can run gasoline, then when it gets to like $5 or $8 gallon, you can buy that Alum. LPG tank I posted about and run LPG @ 115 octane for under $2.00 gal. - by switching to the Bi-Phase Fuel Injectors. If you're running big inch AMC on the Street - eventually, you'll be forced away from Gasoline due to pricing. Join the above groups - read up - know your Options & what salvage parts to be looking for. Can't hurt. That Enderle Mechanical Fuel Injection on eBay is hot - but not for Street daily driver. It's a drag race only item as it stands - and an Antique at best. Mechanical pump & lines etc. will put you back another grand. Three grand money would put a Thiokol alloy LPG fuel tank / EFi system into your Grem and have another 1500+ available for the Snake_Skin Upholstery button tufted headliner. Jay __._,_.___
