Diffrence om617 turbo and non turbo - BRABUS - 07-28-2010
Hello
I´m going to build a custom om617 with h rods.
But whats the diffrence on om617 turbo and non turbo?
I know there are thicker rods in the om617 turbo and it has oil cooled pistons.
Is the pistons and the crackshaft the same?
Is there any diffrence on the head? same camshaft? and so on?
Hoping someone could take the time to answer me.
Best regards
BRABUS

Off the top of my head.
The turbo Blocks have oil jets for piston cooling. N/A Pistons have a smaller wrist pin than the turbo units. Turbo crankshafts are nitride hardened while n/a cranks are harden differently.
Later n/a head castings are the same as the turbo units. Valvetrain is different – the cams have different grind spec and valves are sodium filled. 79 and older n/a heads used the bigger threaded loop style glowplugs, Turbo engines of the same era had pencil style glow plugs.

As well as the turbo unit having a chain driven high flow oil pump instead of shaft driven.
