triple carbing my 80 280zx
 

What is need how to setup and delete efi and what electrical work needs to be reworked and iginotio? Also I have played with dual and triple carbs before just never had to convert from efi

Bro. Don't do it.
I could invest my time on elaborating as to why, but someone else surely will.. just don't. There are no gains except the beauty of the sound, being completely objective. You will burn more gas and tinker more just so you can have a louder, less reliable car.

I'm assuming you're running a naturally aspirated l28 with a normal block and head? Just throw headers on her(To get a bit of the sound you crave) a larger TB (self explanatory with the headers), get a billet fuel rail(To simplify things since you dislike F.I, consider turbo injectors) and megasquirt(to tune and take advantage of your TB & injectors). Eliminate the emissions crap if your state allows and continue from there. Please don't carb a RHD S130.
