just getting some ideas from you smart people out there..i am having a little problem with my engine. 95 ka24de..when engine warms i am having some detonation, i have higher compression and using 93 octane fuel on the street and 104 on the track. i have set my timing to 18 degrees. my question is when the detonation occurs i get a puff of smoke out of tailpipe, it only smokes when the engine pings at temp. any ideas? the engine has been fully rebuilt 2000 miles ago.

What color does it smoke? Are you sure it's not rich misfire?
