  1. Hyper-Eutectic pistons?

     

    I'm not doubting you, I'm definitely not familiar with these 4G engines, but will ask some cautionary questions... I know that the Subaru EJ25's have a lot of problems with the factory Hyper-U's... even as low-power as stock STIs, people have cracked pistons. Note that the EJ25 is quite a large-bore, short-stroke engine, and I do not know what the 'quest's is.

     

    But I'd still doubt the reliability of Hyper-U's until looking into it further. They are indeed nicer as far as cold-start emissions and longevity - both because the heat expansion will closely imitate steel cylinder liners as opposed to forged pistons - but not as strong.

     

    Who is this guy?! lol
