I know this topic has been talked about before.

We have a 2003 2.7 with a auto transmission.

We have a 2001 2.7 that we would like to put in it.

I have been told 2 different things.

1.Will Work
(We will have to change everything as if it was a long block)
(fuel rails, wiring harness, plenums, throttle body etc)
Then it will work

2. It will not work at all
(they have a different timing system and heads)

Which one is correct.

Hope someone knows the infinitive answer.

Thanks Bart

You can substitute the 2001 short block for the 2003 short block

Will the DME work? Mine is version 7.8.

So just so I understand this correctly..

To make this work you have to change the heads for this to work no matter what??

just trying to clarify.

Thanks

No you need 03-04 heads to not have to change the DME. You can install your original heads on the 2000-2002 short block. ( my mistake on my original post as I was thinking swapping short blocks instead of long blocks because Porsche only sells rebuilt short blocks now, no more long blocks from Porsche AG.)
