why would you do that? at least convert it to a 6spd. it's near pointless to switch to a 5mt, unless is was a rebuilt 5mt.

i'm getting ready to do this to a 95 legacy...with a 5 speed out of an impreza (not sure of the year though)...except i'm not sure if the front and rear gearing will match up.

The center diff is part of the trans and they are different, the auto has an electronically variable front-rear split while the manual is mechanical and fixed at 50-50.
You would need to change a lot of parts in the drivetrain, also the flywheel and the ECU.
This is not a cost-effective conversion. If you want an MT car you would be far better off selling your auto and buying one.

i would covert to a 6sp, but i guess if i do that, i rather sell it and buy an sti, cause its very pricey as you probbaly know, however, i think that its more economical for me to not sell it and convert it to a 5mt, it has many mods and i think its less of a hassle to put in a new tranny with all the hardware,s there are several people i found that did it, and looks like its not horribly complicate as it might seem

i think that if you want to keep the price within reason your best bet is to go to several junkyards and pray that you find your manual tranny there...and then you might as well take the other parts like the flywheel and ECU too....keep us posted

well...i found a tranny w/ linkages, pedal set, and needed cables to hook it up for like $300. just need my flywheel and clutch assembly to come in ($50 for the flywheel & $160 for the clutch assy.)

a friend and i will be doing all the work.

i talked to the guy at the salvage yard about possibly needing the ecu...he said he'd just swap me for mine.

just gotta wait for my parts! that's the hard part for me.

being said that the center diff on the manual is a mechanical piece rather than electronic...how possible would it be to get it locked for RWD?? i'd rather do that than risk eating the gears due to the possiblity of the gears for the front axles being different from the ones in the rear end. the tranny is coming out of an impreza...i'm not sure what year (1st gen??) and it's gonna go into a 95 legacy.
