I had shortblock replaced in my 2007 Impreza WRX STi and was charged $5.000 out the door including the cost of new shortblock. The whole engine consists of: -shortblock -heads (pair) -accessories (oil pump, gaskets, etc) They reused my heads since I had cracked piston (infamous 2007 STi issue) so the price included factory preassembled shortblock (~$1900) + gaskets +labor. Depending on the reason you want to replace your engine you might reuse some components.
No you can access the rear main seal by removing the Transmission, flywheel etc
on top of the engine block under the intake manifold. it can be accessed without removing the manifold. easy fix!
