Guys,
The stars have finally aligned and I now have a few $ to buy my replacement engine. While I'm still hopeful that Dave at Japan 4x4 can come through with something new for a reasonable price I'm heading out this weekend to check out some used ones. I have a bunch of info on the 1HZ but the one thing missing from my data is what kind of compression numbers I should expect to see per cylinder if I can get these guys to compression test the engine before I buy it.
Second in all of the data sheets I see the "compression ratio" listed as being either 22.4:1 or 22.7:1" for the 1HZ. How do these numbers relate to the results that folks post after running compression tests on each cylinder of their engines.
Thanks,
John
 
suppose that you already know the comp test method ..

1HZ std comp 526PSI minimun 384 PSI .. IIRC no more than 50 PSI diference across the cilinders ..
