Sorry for your loss..
My mechanic kinda steers me to go efi...But my CIS is running well for now. The HP bug does hit me once in awhile and I start thinking,,then over thinking....Then I come back to earth and say to myself...RELAX and enjoy what you have.
My car plenty fast enough for now. I don't want to start breaking engine parts if I don't have to. I just plan to save my pennies and buy with either 996T or 3.8GT3--God knows what year from now...
It just sucks what happened to you...Any word or explanation from the builder..etc..etc..
Keep the faith.-----(Just read your engine build thread)
