I am building my coupe with a carb. it's a 2.3L FI engine in my 89. I am using the lower FI intake. Racer walsh has an adaptor for the 2 baller 350 cfm carb. I was planing on that. Though on a recent post about the offy 4 barrel intake one poster said that their 390 cfm 4v did well. I would like to do a nitrous set up on it and there are 4v nitrous kits gallor.
So my options are:
option 1: 2v and try to modify the nitrous plate for that. Is there a way to use a nozle like the FI setups and drill and tap a hole in the adaptor plate and spray the N2O that way?
Option 2: use the 4 baller and a nitrous plate and construct an adaptor for the 4 barrel.
Would I see a performance difference between the 2 a 4 barrels(not including the N2O)?

I am thinking that the 2 barrel may be easier to tune and there is already an adaptor so I am leaning that way.
