I figured I would ask this in here since most of these manifolds are being used on FI cars. Is there any 4bbl throttle body out there that comes with compatible TPS and IAC hookups for the stock pcm?

What about throttle cables... where can I get one with the proper ends for the progressive linkage on most of these 4bbl tb's?

 

Accufab 4 bbl TB plugs right in

 

I was looking into that one along with the Accel. What is the advantage of a 4bbl over a single 100mm with an elbow? Does the elbow really screw up distribution within the manifold?

 

if your going to be FI, the elbow wont matter at all.
Your forcing air in, as long as th elbow is smoothe, and doesnt make the air violent it wont matter

 

A 4bbl will be less sensitive to tip in and most likely easier to drive. The 100mm will flow so much air even open just a little that it might make the throttle touchy. Another thing to consider is that the larger the bore, the more area for leaks. So sealing 4 small bores is easier than one large one.

This one will work as well:
