We stock popular EJ reconditioned Subaru blocks, machined with matching piston sets.  All of our blocks go though the same reconditioning process.  If your core is destroyed, we have DIY Short Block Kits in stock and are ready to ship.   All of our blocks include the same paperwork, so there is no difference in our these blocks, or if you sent in your block for service.  We do not offer core exchanges or buy backs at this time.  If you have a core, you must send it in and wait for turn around; or you can buy these today!  Limited Supply!
