specs on 91 2.5 I-4 please!

I would really appreciate the numbers on a 91 2.5 OHV I-4. It started out as curiosity and after countless searches I'm at my wits end. My guess is around 100-115hp and 125-140 torque.

105 HP / 135 in the s10

I believe it's 110hp to be exact. I had a web page that gave you the exact details for every car, but i can't find it at the moment. The only thing if someone could explain to me.... from 89-91 the 2.5 4cyl, put out about 110 hp, while the 85-88 2.5 4 cyl put out only 98 horses? ( i could have gotten the wrong info) The engines are almost identical, everso slight setup difference, but i always wondered about this and if it was true.
