X51 retrofit - whitepaper?

Recommended Posts

I am thinking about having my C2S Cab retrofitted with the Porsche Powerkit (X51). As such I wondered if anyone had the internal aftersales whitepaper instructions doc that says how many hours it should take?

I have the one for PSE but not for the X51.

I have been told by 1 OPC that it would take 25 man hours. This sound about right?

Many thanks,

The process is described in TSB 7/05 1001 Performance Increase Kit Installation Instructions (l No. X51) -- dated Feb 10, 2006.

The TSB quotes 25 hours 20 minutes for manual transmission upgrade to X51.

That includes:

Removing and installing engine and rear lid; replacing cylinder heads, exhaust manifolds, intake distributor, oil filler neck and air cleaner housing; installing rear muffler for sports exhaust system and connecting vacuum lines; adding the letter S to the engine number and reworking rear lid.

Programming DME control module; reading out all control units and erasing fault memories. Filling with fluids and fuel.

Performing sound function test on sports exhaust system.

Removing and installing front apron; draining coolant and installing (middle) radiator; installing air inlet in front apron.

But does NOT include:

Power measurement, test drive or installing switch console with button for sports exhaust system

All TSBs are available for viewing here by Contributing Members.
