From what I could find, JE seems to say no more than .004". This sound right? They are going in a 2.4 turbo build that I plan on running a lot of boost on, 450whp is the goal.

FM always states .0035 to .004 on the JE's I've bought from them. I ran .0035 on my 2.5 and haven't had an issue at 20psi. I run .004 on my 2.2 they're ok but a bit noisy on startup. The one's I'm putting in my 2.5 Masi will be set to .0035.
Rob,
I would say .004. This is what happened to Rocky Johnson's motor in ten minutes of total run time. The guy who put this motor together was supposed "Nascar" engine builder that knew too much to bother sticking to piston manufacturer's guidelines. I tore down motor to find out what went wrong. Piston to wall was tip of iceberg. Not saying that was all from too tight piston to wall butt...We were able to save the aluminum rods out of motor. The rest was scrap!

scary Todd. What's "tip of the iceberg"? I sold the 2.5 8v JE's out of my daytona that had been run for years at .0035 with some very lean a/f's dealing with "tuners" at times and 20lbs of boost once I started tuning and they looked pretty much brand new.

Mine is quiet
I've always run 3.5-4 though with je's on 2.5 and 2.4's been good.

There is no logical reason to call an Engine a motor.
