My advice from a practical standpoint is to put one of whatever was in it back in. If you put a 4 cylinder in place of a 6, or a 6 in place of an 8 everything will be different, assuming something made within the last 20 years. The computer hookup and wiring harness will be all different, exhaust will be custome, fuel delivery will be different. If your time is worth anything to you I doubt you'd ever make it back on a $$ basis for the fuel saved. The transmission might be a slighly different proposition. Gearing it so the engine RPM is slower will probably raise your mileage a little, as long as you're not slowing the engine down into a less efficient mode. There's no sure way to tell without looking at the same kind of car with the different options. A manual transmission should give you a little better mileage as well, but if you've got an automatic now it would seem like a nightmare to setup the clutch and shifting linkage so that it works well. My thoughts, worth at least what you paid for them:) --- David _______________________________________________ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
