I've noy seen a pinto turbo manifold for years

The last one was appox 7 years ago

I had a 2.0is engine in my cortina with over 150000 miles on it

I put a KENT FR34 cam,4 branch manifold,FSE valve,K&N filter(cone)removed the viscous fan and it gave me 128 bhp and 127 lb ft

With 2.1 and a bit more compression and a stage 3 head could have seen 160 bhp imo

Good luck
