Gear Ratios/Speed per Gear 1G AWD

[GSXlaunch]

I was just wondering if anyone could reply with this info or point me in the right direction. I have a 90GSX 5 Speed. I have some 225/50's are all four corners on the stock 16" rims. I am trying to figure out how (if any) this affected my speedometer. I saw this http://www.vfaq.com/mods/Trannies.html but was wondering if there was something out there that included max mph per gear. For instance, 2nd gear should get me to 60 correct?? When cruising at about 70mph my rpms are around 3400rpm. Sorry for the newb questions. Thanks
