    Replacing motor on 2004 WRX, what to do while it's out....?

    The motor on my 2004 Subaru WRX has to be replaced, in fact it's at the shop now waiting on the used motor. I'm a paramedic so I'm good with people not so much with cars and I'm wondering since they're going to have to take the motor out (and exchange manifolds since it's a Japanese motor) what else should I have done in the way of maintenance or minor upgrades? I'm going to have to clutch replaced, transmission fluid and rear differential fluid changed while it's out. Any suggestions? Thus far this is costing less than $3K and I'd like to keep it that way but does anyone have any suggestions of what else I might consider doing? Thanks.

    How many miles on the current car? How many miles on the replacement engine?

    Unless you've bought a front clip complete there is little way of knowing how old the replacement engine really is. I'd be tempted to assume it needs a full 105K service (timing belt) plus water pump and any/all gaskets and seals -- the valve seals are now easy to replace, not to mention the rear main seal. If those are wet now's the time. On the front there's the cam seals and the crank seal to check -- and again, probably the timing belt.

    The current car has 117K miles and the new engine is at 50K.

    Hoses of all kinds, Tune-up. Stuff that SD has already listed, if it's needed.
