QUOTE(Kerr1 @ Aug 1, 2007 - 8:13 PM) [snapback]584481[/snapback] wat do i need for 15 safely? maybe thats a better way of putting it. on what turbo? 15psi on a ct26 like i have, and 15psi on the holset that itchy has are two very different things. the problem with running high boost on a 5sfe is not with the strength of the pistons or the head. its with the fact that its a high compression motor. the higher the compression, the more chance you have to run into detonation when trying to turn up the boost on pump gas. detonation is what ends up killing pistons, rods, headgasket, etc... -------------------- 15PSI - 30MPG - Megasquirt Tuned
