Can I make my PSP system into PS3 system?

May be...

I had update my version of my PSP. After I got an idea if I could change the system into PS3 system! Can you tell me is it right?

No. The PSP's processor and memory would not be able to handle it.

No, you can't, they are different machines. A PSP is a PSP, and a PS3 is hugely more powerful, it will be a long time before something with the power of PS3 could be made the size of the PSP. Given the size of any portable screen, it wouldn't really be necessary anyway:)

Well why do you want to change it to a ps3 system if it is like a ps3 system.

that wouldn't work and even if it did you wouldn't be able to do anything. THe closest thing would be on of those PS3 laptops like Ben Heckendorn's

No. That be cool thou. The ps3 is big for a reason

Simple answer: NO!!

No you cant! Sony cant even do it yet =S
