Gearbox for `58 KG?

[AREX]

Hello all,
I`m new here but not in vw`s garage
Anyway - I was wonder maybe someone has good idea for gearbox to 1958 Karmann Ghia. I`m planing build VW turbo engine about 200 HP
I`m thinking about some Porsche gearbox but I`m not familiar with what type?
Best would be with 5 speed. I don`t want to make big body modifications (unless it is necessary) becouse we don`t have here in Poland many pre-60 KG`s.
