Check with this dude, he's installing a turbocharger...I'm running ~17 PSI. Denso's IK22 work well to help inhibit pre-ignition.

 

Yep, thats what I was thinking.

"isn't this dude going with a turbo...."

If you want to share your work thus far, I know plenty of us would enjoy seeing your hard work.
