Another quick update. I've been trying to get insurance for the car with no luck. Regular insurance will not take it, and classic car insurance requires 10 years driving experience. Unfortunately for me the 10 year mark is this December 17th. I just gotta wrap things up now and throw it in storage till next year. Here are some pics of what I've done recently.
The intake just needs to be wrapped. I don't like the location of the MAF, but it's the only place it will work.

The doors are a huge pain in the ***. The previous owner was converting it into a track car, but I have no idea what he was thinking of doing with this:

I think it's safe to say that the windows won't lower when opening doors, since all the wiring has been cut out. The original door lock switch no longer works for me due to the above, so I got a Jetta window switch and swapped out the rockers. It's a sketchy setup, but at least the doors lock now.

I've also been trying to get the tach working. Unfortunately for me, all the older LS based engines use a 24 tooth reluctor wheel to keep track of the crankshaft speed and position (LS3 uses 58x. Lucky you!). The Porsche engine uses a 58X reluctor, meaning I cannot just plug in the GM sensor into Porsche DME. The other option is to use the tach output signal directly from the ECU. Unless both engines have the same number of cylinders, this will not work without some modifications to the signal. I've got something worked out with Arduino, but I still have to test it in the car. If you are interested, you can see more on this in my blog.

I used the tach output signal from the GM ECU to the Porsche, worked fine. If yours is off, you can go through HP tuners and change the signal to the tach (4, 6, 8, etc).
If running the MAF is too tight, you could tune the car to run off the MAP.
