Opinion on Clifford mods for Slant 6 motors

Seems like am awful lot spent on a slant to hit 200hp n/a. Its a labour of love and enjoyment for me if i do some refreshing and goodies but i dont expect massive hp returns on my money spent.

A turbo will really be the easiest bet for hp, even a simple draw through with no intercooler

Seems like most of the turbo conversions for this motor are pretty substantial, a lot of fabricating to get things to fit. Is that not the case?
