Guess the compression. 

Looks Like Time For Some Forged Pistons!!! Then You Can Get More Boost Out Of It!!! Keep Rocking It Out Down Under Ziggy!!!

Good luck on the repair and maybe a 1.5 swap. We will see what happens. Cheers mate

Detonated Pistons yea,.. heck, seen me a lot of them..do a leak down Zig, that won't be cheap in the end, dam 200!!!! Got one helluva a good one in her still,.. Cheers Mate😎

Good on ya mate - I reckon it would be hard these days to find a mechanic who knows how to read a spark plug….. All they want to do is load up the parts canon and you walk out with a bill for two grand

I've never seen a comp gauge go to 200 before. Not that I remember anyway. Yeah forged pistons should be the go eh. Cheers Zig, Happy Easter.

I'll go for 100 in 3 and 68 in the other.

was here :)

LS swap time !!!!

Did you open the throttle body?.
