Does anybody know of any good websites, or forum with information on 1990-1994 Toyota pickup trucks?

automotiveforums.com they have a pretty good forum for any type of car. Im sure you can find some people with a truck from that time period

tacomaterritory.com

Those trucks aren't Tacomas so I don't know how much info there'd be on a Tacoma site.

You can try www.yotatech.com

Those are great trucks...extra cab versions were available in all those years and they came with the 22RE 4-cylinder or 3.0 v-6. The 22RE is a very reliable engine with decent fuel economy. The 3.0 is not Toyota's best engine....it's heavy and doesn't produce that much power, and it had some trouble with head gaskets. It is a very smooth powerplant though, and many people like them, but I'd go for the 22RE if I were buying this year of truck.

The 4WD versions have chain-driven transfer cases with a 2.57:1 low range and all trucks have independent front suspension with torsion bars.

Many people prefer this truck to the Tacomas in suspension, body, and interior design. The Tacomas got new engines that outperform the truck engines, however.
