Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

What does it take to drop a 3.2 Boxster engine, into a 1999 996 that had a 3.4 in it? 1. Do I need to swap wiring harnesses? 2. Will the 1999 ECU recognize the 3.2 without any CEL? 3. Any parts need to be swapped from the 3.4 to 3.2? 4. The 99 is a Tipronic. Does the 3.2 HAVE to be a TIP also, or can it be a manual? Here is the reason. The 99 just had massive engine failure at 145K on the car. Otherwise, the car is in great shape, Tipronic and all. 3.2 engines are a lot cheaper than 3.4 engines on EBay. I know I will be giving up some HP. That is ok...This is simply a DD car, to and from to work and running around town. I use it to keep from running up the miles up on my 2002 996 Convertible Six speed.

Have you taken a look at our Boxster Engine Swap / Carrera Engine Conversion DIY tech article? Should be somewhat similar... Either way it has a lot of great info so be sure to take a look at it here: Porsche Boxster Engine Conversion Project - 986 / 987 (1997-08) - Pelican Parts Technical Article . We did this to our in-house 986.
