coprims

i have seen it done before and a mate of mine has an 87 skiline with a motor out of a VL calais turbo and we dragged him and got destroyed and this guy was only running 8psi of boost, we were running 10

I have recently purchased a VL Commodore, low km's, immaculate inside and out. This car will be used as a run around but i really would like it to go a lot faster. A small 4AGZE Supercharger has come my way and i dont really think it would be that hard to bolt up, this is my first experience with a nissan motor. I am not really worried about the internals of the motor as i only want to run aroun 8-9 PSI of boost. What i am worried about is the fuel delivery. How much power can the stock injectors, fuel pump and computer handle? Would it be worth getting some injectors out of a turbo RB30??
