proper procedure would be to remove the pistons first, its got two plugs on the front, one on each half, and two on the back, again on each half, once you take them out, i think they are a m14 allen head, rotate to tdc, remove the wrist pin circlip, its a c-clip that holds the wrist pin in the journal, and slide it out from the back side, you're do this on each of the cyl's

 

then look for the bolts that hold the block together some are visible on the other shell, some are in the coolant areas near the cyl's

 

probably didn't explain it well, been a long time since i did this for the very same reason...

 

best best is to get a service manual, advance sells them for $15.95 and can usually get them in a day or two, it should have the full write up of the process since i'm sure i overlooked something

hmmm yeah i have know idea....remember im still a noob....ill try to fond a factory service manual...

the haynes would have everything you'd need unless you can get somebody on here to scan the fsm pages for you, i don't have a scanner or i'd post up some from my chilton's manual,

 

just have fun with it, at least you are doing it to learn and not needing a motor rebuilt now, it'll be a good learning experiance since most all subie motors are assembled/disassembled in similar ways
