Gear ratios on 90 integra vs 91 integra

[90gs]

I had a 91 integra gs, now i have a 90 integra gs and the ratios are different.. by kinda a lot

90 integra
GEARS - 1st - 2nd - 3rd - 4th - 5th
RPM 3000 3000 3000 3000 3000
SPEED 13 25 35 47 60

91 integra
GEARS - 1st - 2nd - 3rd - 4th - 5th
RPM 3000 3000 3000 3000 3000
SPEED 19 28 40 54 65

5th gear seems longer geared on the 90 than the 91 too (if thats the right term). for example 5th gear on the 91 was strictly RPM/100*2 (3000rpm=60mph, 3500rpm=70, 4000rpm=80, 4500rpm=90) but on the 90 its like 1900rpm=40mph, 2500rpm=55mph, 3000rpm=65mph, 3600rpm=80mph, 4000rpm=90
