ALFA Busso 2.5 V6 induction

[dazaroo16]

I'm currently trying to decide between switching to individual throttle bodies, using a Larger Throttle Body (like a Ferrari f430 Throttle Body conversion) or to Create a Custom induction manifold from carbon fibre and heat-wrapped with twin throttle bodies with ram air style cold air input like on a Ferrari f430

i want to keep it NASP and below 260HP while improving torque as much as possible (my 156 is FWD and i don't want to overpower it),
im after a lightning fast throttle response

Any ideas and pros and cons as its currently my daily driver with 210 HP tuned and for torque
