Description

Subaru blocks are made out of aluminum and can sometimes react adversely to heat, slightly changing clearances with temperature changes. This consequently makes the engine less consistent and less reliable. Inserting a Ductile Iron Dry Sleeve into an aluminum Subaru block reduces the amount of warp, and remains a consistent size and shape through its operating heat range.

Dry Sleeve means that the sleeve does not contain water/coolant passages bored through the sleeves. This solid design provides a more rigid structure to prevent warping and sleeve expansion.

These sleeves come as a 98.8mm bore, and can be bored out to 102mm.

  • Q: Piston Pin  joy_alam 3 years ago

    Answer

    I just got the sleeves few days back from here. Quality is great. Just one question, there's no hole for piston Pin to go in, do i have to drill that bit myself?


    • A: The wrist pin access hole will need to be machined in to the sleeves once the sleeves are fitted into the block.

  • Q: Clearance question  Chris88 4 years ago

    Answer

    Will these work well with Wiseco Piston Set 100mm Bore Subaru Turbo 2.5L (inc. 2006-2014 WRX / 2004-2015 STI) and if so what would the clearances be?


    • A: These sleeves come as a 98.8mm bore, and can be bored out to 102mm. These would work with the Wiseco piston set but machine work is always required when installing sleeves.
