  • Q: WHAT IS THE PROPER HG TO USE  Pumbaa 10 months ago

    Answer

    Hello i have a 2006 WRX wagon. I am doing an engine swap. the motor is a EJ257 from a 2011 STI. The heads are the D25 heads from my 2006 WRX. what is the proper HG to use? what thickness would be the best? what bore diameter will I need? should I get a HG for the 2011 block or the 2006 heads?


    • A: For your hybrid set up that you are doing you are going to want to match the block so you will want to get STI headgaskets. The rest depends on what you are going for. Sizing plays a huge role in compression ratios so you will need to consult a tuner before purchasing or setting up your block.
