im interested in the head shims...
do they completly replace the headgasket???
or do they work like a decompression plate needing a headgasket on both sides??
a mate who is running a a14turbo with et pulsar pistons(modified dish) recently cracked them on 12psi with an excellent tune.....
we later found out the pin let go and that caused it to crack.
he is now temporarily running his tubo setup on a dead stock a12 @ 8psi.. it has been alive for 3 weeks now and is starting to get very smokey under boost..
i wonder how much longer it will last.
