My 1983 300SD uses the KKK turbo. Per the book, they started shipping the KKK (in addition to the Garret) in 1/1983 and mine is a late 1983 car.

I checked the boost at the line between the changeover switch and the ALDA and I'm getting 10 psi.

I would like to turn this up to 14 psi (just shy of 1 bar) and remain within factory spec. (<1.1 bar).

The adjuster on the KKK is on the right hand side of the turbo (from the driver's seat) and is very close to the frame. It uses a 10mm lock nut - I can get a 1/4" drive socket in there to loosen the nut but then I have insufficient room for my ratchet. Any ideas how I can get in there? I assume you turn the adjuster in to get more boost?

Also, what is the corresponding adjustment on the ALDA to enrichen fuel flow?

I have searched the archives and they seem to focus on the Garrret turbo.

Thanks in advance for any help.
