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?
