your engine might breath a little better with a carb setup and that might give you a couple hp over a stock rx7, but there is no comparison, in programmable fuel injection and a carb
fi= better in every way shape and form
carb= less complicated

Carb:
cheaper
simplier
more hp vs stock efi: no afm, less restrictive intake manifolds
tuning can be a hassle, every 10 deg jets need to be retuned
hard cold starting/running
harsh, abrupt powerband
Aftermarket efi
more expensive
more complicated
WAY more control
WAY more tuneablilty
Makes more power than carb
Moral of the story if you have money; you have aftermarket efi

carb:
easy to tune
cheap
not verry good for turbo setup
hard start on cold weather, speacially 30 and below
great power
sucks on fuel mileage
FI(stock):
non tunable
not cheap sensors
on N/A you cant put a turbo or in turbo II is verry limited
great HP but limited
great fuel mileage
and with the right stuff is easy to start on the winter
FI(tunable):
from what i heard is hard to start in the winter
depends of the tuning it can suck or be good on gas
depend of the engine configuartion can get alot of HP
can be tune for turbo
not cheap at all
pic your choice.

there are NO advantages runing a carb then EFI
the power u are gettign is nto coming from a carb but the manifolds that u
have to change out to put teh carb on which flow a lot better then the stock
ones, if u get the racign beat lower manifold and then some twm fuel
injection throttle bodies u will be able to make same if nto more power
because of the better tunning tha tu can achieve with the EFI.
carbs are not cheap and goign with the twm is either it pretty much
comes out to be the same price but EFI is much better.
