Thanks for the replies guys. Yes GP it is the murena specifications I am looking for. I have the ones for the N9TE, And have have had to have the crank refurbished for 0.2 oversize shells. The reason I am asking for murena specs is that the rods for my N9TE engine is the ones without oil spray holes for under the pistons, so I figured I can use murena bearing shells , which is much easier to come by.
Is it wise to use con-rods without piston oil-spray holes? Turbo engines generate more heat so the idea of the oil spray to the underside of the pistons is to help cool them, as I imagine you understand. If it was me, I would want all the cooling I could get. If these were originally fitted to the lowest power spec. turbo, that doesn't always mean the oil cooling wasn't actually necessary; just that the manufacturer didn't have the right spec. at the time! They then get feedback suggesting they need more cooling, and the next 'improved' version of the engine includes the piston oil spray (via the con-rods).
