I put the sleeves on the center bolts only. I think I will do the outers next time apart..
15* is a starting point because I have no Idea where the boost will end up.

Ok i was just mentioning it because low timing will act that way..
At 38 psi im at 23-24 degrees . I use e85 like you ..
A friend of mine wanted to be conservative so he ran 10 degrees. He ran it like that for a few months. He burnt off 3/8" of his turbine wheel tips. shows how much heat goes into retarding the ignition. I realize your running a belt. But just sharing a learning experience with you... His is a 6 cyl 2jz . so his combustion chamber is different . But he went from 623rwhp to 740 rw going from 10 to 20 degrees..
Thats good . Yeah best bet is to do the outers as well. When i did mine there was a settling process. It needs to be re-torqued when its cold everytime until it stops moving. Might take a few times.. I dont believe in loosening to re-torque . I just set the wrench and pull on it. If it moves it moves ... Mine always did. Now they stay . No movement..
