Source a complete manual transmission setup from a salvage yard, including the clutch master and slave units. Plan on changing the axles and swapping the computer. Expect the conversion to cost roughly three times as much as replacing the automatic transmission.
The owner of a high-mileage 1991 Acura Integra LS asked how much work and money it would take to convert it to a 5-speed manual. The expert said the brackets are already in place and recommended obtaining the complete manual setup, including master and slave units, from a salvage yard, along with changing the axles and swapping the computer. The conversion was estimated to cost about three times as much as replacing the automatic.
