Hi everyone out there in Subaru land
I have a Subaru brumby 88 ea81 motor,I'm wanting to rebuild it soon but interested to find out some modifications to give it a bit more go,can some one help with ideas?
Also I'm interested in hearing from someone who may have fitted a 5 speed box to the ea81 donk.

for exhaust, you can use the header pipe off some later model ea82 fuel injected(spfi) for more flow, then cusom after the flange, the spfi pipe is tuned just right for subaru, that will get all your scavenging effect.
it is possibe to use the ea82 motor from later 85-87 carb ea82, in conjunction with the 5spd dual range box.

i myself have had an ea82, 5spd, and ea82 front suspensions, rear discs in an 83 wagon.. dependint on what motor/tranny combo you use will determone you clutch/flywheel configuration. if your motor needs rebuilt, maybe you can consider an ea82(timing belt) motor for replacement. thw motor itself will fit with no mods

the way i made my mods was to mod the car itself to accept stock(replacement) parts. feel free to ask anyhing specific
