Cayman 3.4 engine into Boxster S 3.2

[recycledsixtie]

I can relate to this thread from the seller's viewpoint a few years back. I had never seen the CEL come on while the engine was running in my old 99 Miata. I sold it in the morning to this gal and the boyfriend was with her. A few hours later I get a call from the new owner and she says in an assertive voice " I have the CEL lite on. What is it about this car you are not telling me about?" I said that I had never seen the CEL lite on before which was true. I told the owner before me and the Pres. of the local Miata club. They both offered to go down and read the codes.

The boyfriend must have settled her down and later fixed the offending O2 sensor.
If it was me that sold you your Boxster I would have refunded you some $$$ but not everybody is like me.

Here is link to a post on this Forum where the car had exactly the swap we are discussing.So it is doable -the question is:
1. how to deal with the electronics?
2. and is a Tiptonic O.K. for a manual recipient ?
If someone covered this in all the vital details, plese tell me.

That 3.4 engine is from a 2001996. If I read you correctly you were thinking of installing a 3.4 Cayman engine. The older 996 would be a more compatible swap. Same displacement but quite different w electronics.
