Engine replacement question
Good evening -
I recently acquired a 2005 Boxster base 6 speed manual transmission car (2.7 flat six) that I knew needed some engine help. My local shop has determined that the IMS bearing has disintegrated and the engine is a goner.
I have been researching used replacement engines to put in the car.
My question is this:
Will any year 987.1 2.7L motor work for me or do I need to get a 2005 engine?
Most of the engines that I'm looking at come with everything but the alternator, starter, power steering pump, AC compressor.
I found a 2008 2.7L engine, but before dropping the coin to have it shipped to my shop, I figured i'd see if anyone knows the answer to my question above.
Thanks!!!!

Look at the engine serial# on the near the sump plate. Can you confirm that it's a M96.25? Installing a M97.20 would be problematic. I wouldn't recommend this transplant if your car is setup for the M96.25.
Please confirm.

Sorry to hear about your engine failure associated with IMS bearing failure. So many people don't know that Porsche used the most problematic bearing (6204) on the first run of the 987 Boxster. Many think they went with the 6305 on all 987 cars.

Great news! I think in the long run, you'll be thankful you didn't overcomplicate this decision. A lot of the conflict has to do with some of the improvements/slight changes on the mechanical side of the M97.20 and your current DME version which is programmed for the use of the M96.25. Therefore, sticking with the right version of engine while making component improvements (e.g. swapping out the problematic 6204 IMS bearing and installing a IMS Solution) will make the M96.25 as durable as the M97.20.
