91-93 are really really gutless
93-97 are really gutless
All 80 series are gutless by today's standards. Especially if you live in a mountainous region and do a lot of elevation gain.
My 91 with 280,000 miles did get better gas mileage than my 97 with 120,000 miles on the clock.
After owning both I would say get a 93 or newer. Not because of the power difference but because of parts availability. The 3fe has less new parts available and it would be a harder motor to get rebuilt correctly.
Oh yeah, and none of this is true of you live in Cali. In Cali they will both get 18+mpg, clear 37's with a two inch lift, and have enough power to tow a 30' boat......
