6.5 turbo on a 6.2 ????

[hyper14h]

my brother has a 86 chevy truck with a 6.2 and hes looking to get more power. i have a turbo and a down pipe from my old 6.5 and i was wondering if the 6.5 intake and exaust manifolds will bolt up. and we were talking about puting 6.5 marine pump and injectors in it but i didnt no if the injectors would fit i no there was differnt sizes, lengths, and treads threw the years of the 6.2 but dont no if the 86 has the right ones or not
