FD specs?

[RXpilot]

I have looked through the search but i cant seem to find if anyone knows year/model final gear and estimated top speeds... does anyone have a link or this type of info, i found something on one of the US sites but its not very detailed only giving a rough figure for the FD in general.
mine is a Japanese import from 93 and the KPH/MPH convertor is not wired right (searched to no avail on re-wiring to ECU...) and my Apexi PFC only goes to 200kph (i think) I know i can outrun the stock mercs and audis so thats 155+ but not sure how far past it? or how far it will go?
any clues would  be great :driving Cheers
