Subaru

All of our Subaru engines are remanufactured at Sunwest Automotive Engine with state-of-the-art equipment under the strictest of standards using only premium quality parts. Our engines are built to not only meet, but exceed OEM quality. We sell long blocks, short blocks, and cylinder heads and we offer a variety of options including performance packages with forged internals for people that want to get a little more out of their Subie

All engines are remanufactured at Sunwest Automotive Engine's facility in Medical Lake, WA. We ship nationwide for a reasonable rate. Our engines are sold on an exchange basis which means we need your core back. There is a core deposit required that is refundable, as long as your core that we receive back is rebuildable.

All our Subaru Short blocks include

  • New Hyper-Eutectic Pistons with Rings
  • New King Main Bearings and King Performance Rod Bearings
  • Crank is ground and/or polished
  • Rods are reconditioned on both ends
  • Deck surfaces are milled to an almost mirror finish
  • New Rear Main Seal Installed
  • Case halves come out spotless with our new state-of-the-art ultra sonic cleaning process!
  • Long Blocks also include:
  • Complete gasket set (including 6-Star MLS head gasket installed)
  • Reconditioned valves and valve guides (Replaced if needed)
  • Valve seats are re-cut with a 3-angle valve cut
  • New OEM timing kit installed
  • New Water pump installed
  • New Oil Pump installed

The above is a pair of Subaru case halves being honed with torque plates. This is how ALL Subaru engines should be done. Because once they are torqued down, they mimic the cylinder distortion of an assembled motor (as if the heads were bolted to it). This keeps our clearances EXACTLY where we want them.

All Long Blocks are pre-ran on our SIM test machine to give an accurate reading of oil pressure, cylinder compression and engine load

Machine Work Done:

  • Case halves and heads are cleaned using our NEW state-of-the-art Ultra Sonic cleaner
  • Deck Surfaces are checked and milled to an almost mirror finish
  • Blocks are honed with deck plates to mimic the cylinder distortion of an assembled motor
  • Blocks are honed with a computer controlled Rottler diamond hone
  • Rods are reconditioned on both ends (exc. FA/FB where rods are replaced)

  • Deck Surface is CBN milled on a Rottler Machine
