    QUESTIONS & ANSWERS

    • Q: Piston Pin  joy_alam3 years ago

      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?
      • 0 of 0 people found the following answer helpful

        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  Chris884 years ago

      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?
      • 0 of 0 people found the following answer helpful

        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.
