I have a 92 legacy sedan with bad motor. Bought a 92 legacy wagon turbo. Do I have to change wire harness in front with computor, or can I change just computor?


hi im presuming your old car is non turbo if so you will have to change a lot of parts over to make it work, you will have to replace entire engine loom, the ecu will need changed over then the fuel pump and all of the fuel lines will need to be replaced with the bigger turbo model ones to keep up also the trans will bolt strait up but will be the major weak point so swap over if possible.

Shifting problems on my 2000 Subaru Legacy Wagon. 4th Gear slips out, won't hold in at all. 3rd grinds when I shift it into gear, but slides in w/o the noise if I let the car slow down for a couple...


I would buy a used Trans and fix the other one over time. That way you can take it apart and it might not take a lot of money to fix it. Then you can sell it or save it. Also you may look at the different trans to put in yours. Maybe a Legacy GT 6 speed. Good luck and have a great day.
