What are the differences between the 2000 and 2005 engine? Another 30 horsepower would be a sizable gain and it obviously doesn't involve forced induction or a larger engine.

Can anyone help?

Thanks!

On top of the better computer software and variocam plus, I think 05+ have better exhaust manifolds with equal length runners. The manifolds on the 986 look like they could be a lot better.

Thanks for the responses guys! I'll start with the basics, intake, headers, exhaust, and see what that gets me, if I'm not satisfied... well, I've got some spare turbos lying around...

Spare turbos....hmmm....read some of our interesting ideas about intercoolers, meth injection, and forced induction on the board. We have had some great threads.

Welcome to the slope. Watch out its slippering.

I've got two low mileage TD04 MHI 9B turbos from my Stealth Twin turbo. They would each be good for 11 psi to redline, and I'd really only look to run wastegate pressure of about 5-6 psi. As for intercooling... I'll have to research what is available and what will fit. I have not taken anything apart yet and haven't even seen the engine itself yet.

From what I've gathered so far though, most Porsche owners don't do modifications to their cars themselves in fear of screwing something up, which is understandable due to the cost of repairs to fix a mistake. However maybe I can help change that a bit...

Has anyone on here rebuilt their engine themselves? Or even taken out the engine/transaxle?
