Default 3.6l for a 2001 C2?

Having put 137k miles on a 1999 C2, I had no fear buying what looked and sounded like a clean 2001 C2 with 79k on the odometer.
10k later she’s developed piston slap. Still runs strong but I know it’s a ticking time bomb and I’m a crazy road trip guy.
So, I’m about to go
shopping for a rebuilt engine or a low mileage used one and I’m wondering if using a 3.6l engine from a 2002 or later 996 is a plug and play operation or are there extensive mods to get the Mark2 engine into the Mark 1 car...

any advice is appreciated.

3.6L is not plug-and-play in 996.1s. You can swap a 3.6L into a 996.1 if you swap harnesses and some other things.

A Boxster 3.2L swaps into a 996.1 pretty easily. Just gives you another option. It's not much less powerful than the 3.4L either. Maybe 20-25 hp difference.

There's a 3.2 in the market place and I'll have a low mile 3.6 for sale when my other motor is done in Feb 21.

Thanks Prelude Guy....had not even thought of the Boxster option....BY THE WAY mines a tiptronic. Does that complicate the swap?
Regards,

No, that should not complicate things.

There is a user on this forum who rebuilt an M96 properly. BYProdriver, or something like that, is selling it. It was originally a 3.2L Boxster engine. Now it's a 3.6L.

If you want to do it right, I would go that route. Any M96 that hasn't been properly rebuilt is a ticking time bomb. His has the Nikies sleeves.

Default I’m in agreement

I’ve continued my deep googling and have to say I agree with your conclusion on having the engine rebuilt with the new sleeves, pistons, etc...
Thank you for your feedback and insights. Hope you are hunkered down and well.
George

That would be me. I do have a 2001 Boxster S engine rebuilt to 3.6 liters. 2000- 2002 engine cases & heads were made from the same aluminum castings. Different accessory mounting threads are required in the heads for 996 or 986 installation, so to install this Engine in a 996 you would need to Drill & Tap some holes in the heads or replace with your heads & just sell the rebuilt Boxster S heads. Here is the link to the rebuild thread: https://rennlist.com/forums/996-foru...6-rebuild.html
