1) WTMF are you talking about? That's the dumbest sh*t I've ever heard.
2) The only Teg w/ a 6-speed is the new DC5 chassis and since you are looking for a used one, you can throw the 6th gear thing out the window. Oh and by the way, the reason you are at 5k at 90kph in 5th is because your current motor and tranny suck so before you complain about something you know nothing about, I'd do some reading. The 98+DC2 chassis had the highest frinal drive in any honda and no you can't install a DC5 tranny on a DC2 motor.
3)
www.kbb.com ( not sure if it applies to you )
4) Seeing as you don't know much I highly suggest you forget about changing VTEC cross-overs, rev limiters or fuel maps. These things are modified w/ other mods such as aftermarket cams, reprogrammed ECU's, etc.
5) Blah, blah, blah.
