    1G Eclipse 1G Naturally Aspirated Pinging/Detonation

    Hi guys,I drive a 1993 Eclipse GS. It has a stock non turbo 7 bolt engine.A few months ago, I noticed a weird noise coming from the engine bay, which I believe to be pinging/detonation, after reading this older thread: You must be registered to see element. I can hear it during normal...

    N/A 4g63

    Did these come stock in any Eclipse or Talon? Is this just an engine with the turbo system removed? Is it any better than the 420a as it sits?I just randomly stumbled across this on Ebay and wondered WHY
