Default A bajillion options for replacing an STi shortblock

I need some insight on what direction to go. I won't know until Monday about the extent of the damage to my STi's motor, or whether the heads are salvageable.

Assuming they are, here are my options:

I have a set of brand new OE Bore CP pistons and oem rings already.

Pick up 2 block halves - Gruppe-s has an old post about block halves for $300 each, and sleeves installed for $1k. Anyone know if that still stands?
Pick up cheap new stock rods, or crower rods
Use CP pistons
Use stock crank (or pick up new stock one)

Guess it depends on the shape of my stock crank. If I go this route, what is the rough cost, including gaskets, to get this thing assembled?


Get a stage II shortblock from a motor builder. Cost to get it the motor and ready to drop in with my heads/accessories?


Pick up a fully assembled motor that a friend of mine is selling. About what can I sell my stock heads and shortblock for, assuming the heads are in good shape, and the shortblock has at least a bad bearing, possibly piston damage?

I also need to figure out if I should pay the shop that assembles the motor to drop it in, or drop it in myself. I have required tools, cherry picker, and a decent amount of experience. Time is expensive, though. Any estimates on the cost to pull and replace the motor would be helpful.

Any suggestions will be appreciated. Oh, and does anyone know the cost of a stock clutch disc and labour to refinish the flywheel?

Edit: I forgot to mention - the more $$ I can save here, the closer I am to going rotated mount, which is the ultimate goal. That being said, it's obviously better not to skimp while everything's apart, I just don't want to waste money on unnecessary parts.

I went the fully assembled route... but that is because I wanted the minimum amount of down time plus it ended up being cheaper. Some friends and I started wrenching about 5 pm Saturday and by 8 pm Sunday I drove the car home.

It cost me $40 to get my fly wheel resurfaced.
