I have an old, dead Pontiac Sunfire that I want to convert to diesel,

[Mike A]

ultimately to run on bio-fuel. Advice? This car was designed to run on gasoline, but a friend of mine told me that I can buy a new engine that runs on diesel. For me, this is more about going green than saving money. The car originally was designed to run on gasoline, but I have no problem with replacing part or all of the engine. The old engine blew a head gasket. Has anybody out there attempted this before?

You can not convert the existing engine to run on diesel. Have no idea why you friend things you can just buy a diesel and drop it in. If you have the money to attempt this why dont you just fix the head gasket?

You will have a hard time finding a diesel engine to bolt to your transaxle. You're better off finding an old diesel poweres car and converting it to biodiesel.
