Originally posted by bullettdsm Honestly, I do mine from just past experience on 4G63's and 420a's. My NA's and turbo's have all gotten over 90. I guess I've always looked at the manufacturers numbers as a suggestion. And I work off those numbers as I see fit. Because, obviously, I know better than their millions of dollars of R + D
I went ahead and torqued them to 90. You think that's enough?
