Re:d15b2, d16a6, cam and head decision w/ boost and now w/melted piston pics
 

My car is pretty loud. I couldn't hear any pinging. My car hauled ass. I know that. I always ran 93 or 94 octane. I had a block guard and my car was always overheating. I guess the timing being off combined with the top of my cylinders not getting sufficiently cooled caused this. My cylinder #4 sleeve was starting to crack also.
