355nation is another forum specific to the Atlas engine variants. After the Atlas4200 site went down, some of those guys migrated over to here. A lot was lost when that forum ceased.
Thanks, I posted and was on there some years ago but when I looked yesterday couldn't find any posts there on the I4, I5 or 4200. Have you seen anything on there about any of those that is recent? Maybe I was looking in the wrong place. There was a pretty good following for the I4 at the time.
Did find a great YouTube channel where the guy made over 800 RWH with a 4200 only using a turbo....
Blew it up on the last 800+ run but was making dependable 600 RWH to 700 RWH. Wish I was younger, I'd jump on that.
I'm now in contact with him and I'll see where that goes. Hate to see my stuff go to waste if someone could use any of it,
