1. If your coming out the tailpipe using a sniffer (NOT RECOMMENDED) you're good at 12.0. This method of course is not recommended because of inherent inaccuracies but, some of us do it anyway.
2. If your measuring it, like you should, about 16" from the turbine using a wide-band then 11.5 is good. Like someone else mentioned, 12:0 is ideal. At WOT if you're at 12.5 you're heading for trouble.
At that compression ratio 11.5-12 measured at the the second position should be perfect.
Both SR20DETs and KA24DEs have piston oil squirter's.

not the ka24e
but yeah de has them, it also has a dual timing chain which fails
not a fan of KA
