Identifying factory replacement TT engine

[Live2shift]

I just purchased a 2002, 996 twin turbo that had the engine replaced at 49k miles under warrentee in 2006.

Q1: I want to identify the engine as new or refurb, and also see if it is the same as stock/original.

Q2: I am also am not sure what exactly was replaced, I am a first time porsche owner and not yet familliar with what I am looking at in the engine compartment. I am wondering if they replaced everything including the turbos?

Paperwork from dealer says the part replaced and core return were: 996-1000-971-X

Markings on Case 996.101.198.OR, EN AC-AC 518 Cu3,

Engine plate S/N M96/706450xxxx (xxxx kept blank)

thanks! :drive:

Then the engine is a exchange engine. This engine could be new or refurbished depending on available stock.

The paperwork should say 996.100.971.X -- this would be a MY05 engine.

Thanks for replying.

I realize the engine is an exchange engine. How do I tell if it is new or referb?

If it is MY05, then is is built to MY05 specs or is that just date of build? thanks

I think all refurbished engines have part numbers that end in letter (i.e. X, AX, EX, etc.) whereas new just end in a number.

Built to MY05 specs -- but likely built in 2005.

Mine ends in a number so It looks like if could be a new one. When the factory replaces the engine, what do they replace? Is it everything including turbos, and exhaust? Or is it more of a short-block replacement?? thanks :jump:

I'm not sure on turbos as I have seen many. But, on Carrera's and Boxster it is usually everything except the AC compressor.

I had a professional inspection yesterday and all looked new (not sure about A/C)

Exhaust and even the turbos were brand spankin new, thank you Porsche!

thanks for the help :clapping:
