3.4 engine swap Q&A

[itsnotanova]

I'm very close to installing a 2001 3.4 into my 2000 Boxster S and I think I mostly comprehend what I need to do. I have the "101 project for your Porsche Boxster" book and I've also been surfing the internet on other engine swaps. I've got a few questions for those who might know.
1) What flywheel/clutch do I use? The 3.4 had a really good clutch on it and I'm hoping to reuse it.
2) I have the cluster, immobilizer and DME from the 996 cab. Besides running another wire to the cluster for the oil pressure gauge, it's just plug and play right?(using the 3.2 engine harness). There shouldn't be any reason for getting the 996 DME reprogrammed. The 3.4 DME will still think it's in a 996 cab?
3)I have a 987 aluminum engine cover. I won't need to lower the motor any to clear the 996 intake?
4)Is there a verdict on which fuel rail is better/easier? 3.2 or 3.4?

Thanks Woody
