turbo technics pinto turbo manifold

still collecting parts to build a strong pinto turbo so far i have

205 block
efi
cast iron turbo manifold ( is meant to be from turbo technics )
injection rods ( will replace with cosworth rods )
cast pistons ( will replace with cosworth pistons )
hybrid cosworth T3 turbo
2wd cosworth intercooler
2wd cosworth radiator

my main problem is how strong the manifold is and i need to decide if it is better to turbo the pinto or fot the turbo to my 24V cosworth any ideas ?
thanks steve
