psi is irrevlaent, is all about CFM's casue every trubo varries, so a large turbo at 8 psi will put signifigant more power, then a much smaller one..
your fuel rail is fine, u will need to upgrade the injectors, and getting a hp fuel pump isn't a bad idea... DO NOT use an FMU, that is how u blow motors, u should look into investing into some real engine management, like hondata, crome pro, AEM EMS...
There are a couple important things when doing a turbo car, one is your fueling(big enough injectors) 2. your Engine mangement, and 3. your tune.. those will be the determing factors in a lasting turbo system vs. one that will not last for all that long and not be reliable...
