My imported Hilux Surf (For some reason they dropped the 4Runner name for the non-US markets, although they were called that here in the 90s when they were officially imported - we never got the 4th gen onwards) is a 2WD 2.7 with no low ratio, I found out by digging around it's a common Tacoma configuration.
I don't think it was ever offered in the US...why would you guys need a small engine?
There are no zerks on the prop-shaft, which puzzled me for a bit while laying underneath it with my grease gun.
I suppose I could find a Tacoma forum, but I like it here.
