I would agree with EIFFEL, the second time i did it was very close to his estimate it took me a little less than 5 hours. The first time i did it was when i did my auto -> manual conversion so i was at about 18 hours but that included exchanging the computer, guage cluster, shift assembly, motor mounts, rewiring & rerouting coolant lines. Plus running to the Acura dealer a ba-jillion times.
With all the little quirks & order of removal still burnt into my brain.... i didnt have to pause to scratch my head about anything, it is definitely doable. NO WAY IN H*LL i would only charge 5 hours of labor though, I would match the dealer's time estimate FOR SURE.
