Wouldn't mind these for my D15B4:

Coupled with a Rowland M043 intake manifold.
I will eat B16's for lunch! And will cost half the price of a conversion..And this coming from a Carby haha.
Just give me some time fellas, I want to preety much have more power than a EK4, since the B16 came stock in them, they're around the 6-8k mark, so I will need to work with my D15B4 twin carb motor, produce better 1/4 mile times then a EK4, better power at the wheels then a EK4, and all of that for half the price of a EK4. Then we can finally close this case.
From different perspectives, its about 3-4k for getting a B16 intalled into a EG, with half of that money, I will try to make the car faster then a B16 EG with a twin carby!
