G’day mate, you should slip this back over to the L series sun forum where you originally had it. You’ll get more replies there.
This forum is for EJ series engines/vehicles. The EA82 is the L series which is in the 80’s subforum.
All the best with finding the issue. You must have some sort of shirt that you need to track down.
Cheers

Your guess is as good as mine!
If you’re doing a rebuild, why not drop a set of turbo pistons in there as these are really the only difference between the NA and turbo shirt blocks.
If you’re after power/torque, best bang for buck is to do an EJ conversion, hands down. More reliable too!
Cheers
