997 turbo engine Q

Im looking for a replacement engine for my 2009 997.1T Cabrio.

By doing the relevant searches I have found that the correct part number for the engine of that car is 99710097011.

But there's a different engine for older 997T which has part number 997100970LX.

Both engines are 3.6L turbo, but what's the difference and would they both work for my car?

Thanks in advance

The 99710097011 part number is a 3.6l w/turbos engine for a manual transmission equipped car for MY 2009. At Sunset Porsche Parts web site this is listed for around $65K.

The 997100970LX part number is a 3.6l engine for the Turbo or GT2 equipped with a manual transmission. The applicable years are 2005 to 2008 and include both the 3.6l and 3.8l displacements. There is a bit of ambiguity at least to me arising from the different displacements. Price is around $53K but there is a $7560.95 core charge.

Based on the above info it would appear the engine associated with the first part number is the one for your 2009 car.

However, I offer no guarantees. My advice would be to check in with a Porsche dealer parts department with your car's VIN and learn what engine part number comes up. You want to be darn sure you order the right engine as I think returning one of these if it was wrongly ordered might be a real problem.

While I can understand the attraction of saving $12K (assuming there is no core charge levied) by buying the engine with the part number ending in 'LX" I would urge you to not try to fit an engine intended for an older model year car into your 2009. There is the question of whether the engine would physically fit, bolt up, connect to the car and the various hoses, pipes, manifolds, etc., and would the car's engine controller be compatible with the older engine.

Thank you for your detailed reply! I am definitely been trying to find about the physicial differences between the two engines, because im needing the first part number for the car and brand new is worth the same as a running car.

So the option is to source for a second hand engine, and be sure it fits to the car.

Well, based on 2nd hand info I don't believe there is a 2nd option regarding engines. There is the engine that is specifically intended to be mated to the car and there is .... nothing.

Swapping engines with modern cars is almost always a real nightmare. There are changes in the wiring harness, the engine controller, the very intricate intake and exhaust plumbing a Turbo engine requires, possibly hard points to which the engine/drivetrain use, and so on.

Unless you know someone who has done what you seek to do and you can verify to your level of satisfaction the amount of work (and cost) is acceptable and the results are acceptable the 2nd engine option may leave you with a big expensive paperweight and still a car with no power plant.
