Hi Ho Silveredition,
Ive recently rebuilt 12HT (500km on new engine) and can report the top ring lands (factory- non alfin) were in poor cond with major ring slap.
Unfortunately dont know engine milage at time of rebuild.
Having recently gone through many of the decisions you are now faced with I have a few comments:
Consider fitting a cheap 2H to get you around while you rebuild 12HT- I stopped counting at $10K, but had a lot of work done.
I have access to a few in Kalgoorlie- where are you. I head to Perth often.
I built 3" dump pipe and engine pipe then connected to 2.5 inch I built previously. cheap job but you need to enjoy MIG welding to do it.
I have a single straight through muffler and no resonance issues in a ute with outlet just behind rear axle. - wagon may be different.
Turbo is the best muffler you will find so dont be afraid to go high flow and low restriction muffler.
Ill try to fit a few photos to this post- No guarantees. give us a yell anytime.
