The stock motor would probably be fine…assuming you don't currently have to much blowby. Lifting the heads is a common issue with the stock head/headbolts too…but it's not typically experienced until a couple more psi of boost.
As far as the fuel system goes…your going to need a 255 h/p in tank pump along with some 42lb injectors and matching MAF. You could go with a lightning MAF but it will require a tune before you can drive it at all. If you keep the boost level's at 8psi or lower it's possible to "get away" with using a fmu and the stock 19lb injectors…but most certainly won't recommend it.
