So detonation breakes apex seals! Ask me how I know! It lasted me 4000 miles. It was a fun 4000 miles though. When I rebuilt it I replaced everything but the apex seals. BAD MOVE!!! So I was getng on the freeway just filled up the gas tank. I was pulling through 2nd @ 9 psi slammed 3rd heard pop. let off the throttle kank, then no power and rough as hell. Sweet now I get to crack it back open put new apex seals in and port it some more!!! LOL!!! I'm a fuggin idiot... Oh here's the best part I have neen running Arco 87 octane with 2 storke cause I'm cheap and it had been fine. So I filled up with 89 and put in some MMO. and now it detonates. Lesson don't buy Citgo gas...

No offense but you need to be hit in the head for running 89...and arco...comeon...get a DD your will be much less stressed. Well Check out the other thread I have some apex seals that I might be willing to sell you...

another thing to think about is was your timign the same as when u were running NA?? most turbo cars pull a degree over timing per psi....
