Oh hai guyz
Yep I have done this and surprisingly it is the engine that has not blown up, I have been using it as a DD for about 4 years now and even taken it to a couple track days. My engines that blew up were the stock pistons and one with silvertop pistons, go figure (normally due to something retard but anyway....).
I run it on 91 with the timing knocked back a little but even if I bump it up it doesn't ping or detonate or...anything. It even idles at a healthy 900 revs all day long
