Description

If you are going through the perils of rebuilding the EJ20, you will want to use the right type of piston that can sustain high-performance driving conditions where boost is increased, or where you might be using the vehicle for racing purposes. With that said, Cosworth has developed the 86.5MM 9.2:1 compression ratio piston that has been manufactured through the same careful forging process that is involved with the pistons developed for Formula spec applications. This is a complete piston set that comes with premium rings that have been built to reduce friction and to reduce blow-by. Also included are a set of premium wrist pins, and finally, these pistons have Cosworth's anti-scuff skirt coating with polished tops.

  • Q: Stock Question  Darkendays488471 1 year ago

    Answer

    Being that these pistons are the stock size and compression ratio, will they work as a stock replacement without a tune? Thanks


    • A: Correct, due to these being the OEM bore and Compression Ratio it will not need anything. However, with forged pistons being stronger vs oem a new and improved tune would be be very beneficial.
