1. What would be some advantages of swapping to a turbo ECU and should I do this?

To have the fuel/timming maps for possitve pressure..

2. I am obviously going to have to upgrade the fuel system. I was thinking about 450cc injectors like the link above stated. If I switch to a 2g turbo ecu will I still need the SAFC?

Any injectors larger then the 450's will require some type of fuel mangment..

3. I will upgrade the fuel system with a Walbro 190 pump and some injectors. Besides an SAFC what else will I need. Will I need a fuel pressure regulator if using the SAFC?

You will need a 2g turbo FPR set to 43.5psi, 440's and no other tuning device... If you choose to get a 255lh or larger you will need an AFPR that will allow you to lower your fuel pressure; like the Aeromotive 13109..

4. Will I need any additional tuning besides setting boost and tuning the SAFC?

If you choose to use an safc2 you will need a pocket logger to log RPM, Timing, 02, Airflow.. And of course a Wideband if you have the available $..

5. I want to run around 8 psi for now. I may eventually build the bottom end and do the DOHC head swap so I can turn up the boost. With this in mind what will be the best turbo to install. The above link suggested a small 16g or a 14b.

both have extreamly good compressor effencys for low boost.. The 16 just has a higher & wider effency... Choice is yours.. I would stick with the 14b to begin with becaue it won't outflow your walbro & 440's..

6. I will use an aftermarket FMIC. Can I use aftermarket 2g turbo lower and upper intercooler piping?

The UICP yes if you go long route, LICP, No.. You can get a suppra side mount to work with the stock intercooler pipeing... Most FMIC will require new pipeing...
