all thats left is to pull the trigger on 6 Jenvey throttle bodies with a new Colvern CP17 TPS. I'll have to order carbon fiber velocity stacks down the road once I make the 2 CNC'd TB flange plates to weld to the intake runners I'm making and test heights from vertical to various inward angles and get flow results before deciding VS or runner lengths as well as ITB angles. Then there's the whole new fuel rail required and associated hoses along with linkage. Once everything is bolted up and working there's still the air filter and ram air induction to contend with. Not to mention getting the CF hood to close on it all with clearance unless a hole/scoop becomes mandatory (ICK!) Then there's anodizing/powder coating to get all this stuff looking like it was custom made for my car.
But at least I've got a carved-in-stone plan now and along with it the direction and focus to take on a project of this complexity.
Pic above is what I'll be using ITB-wise but not in the "cross-flow" layout. (It was the only v6 config I could find using Jenvey ITBs).

if it comes to that anything will be non-stock and not my first choice. If its an inch or less...
I'll lower the engine as I already have engine/transmission mounts that have that much adjustability machined in. If its more I'll likely compromise some flow to keep everything under the stock hood.
I just cant like the idea of any hood "tell-tale" advertising what might be under the hood.

awesome! there goes the "factory look" your engine bay had...but well worth it I am sure!
Will this decrease your low end torque or is that wholly relavant to the runner lengths you choose/can fit?

Oh yeah Alfa V6's at full throttle are like an aria being sung at the Milan Opera house....
somethng to experience. The sounds that engine makes is nothing short of heavenly, something the Germans yet do not know how to design in.
