Too bad we can't use stock second gen non-turbo RX-7 injectors in Hondas, they are 460cc and can be had for $5-$15 apeice. They are top feed, but I don't know how they compair and I don't know of anyone who has tried it.

Your best bet would be some DSM injectors, but as previously mentioned 6.5 pounds of boost from a T3 isn't much air.
