here is my set up for my 93 delsol:

greddy 15g
bbk fuel pump 225
stock injectors
greddy profec b boost controller
blitz turbo timer
guages
spearco intercooler.

if i use Vortech fmu 12:1 then i dont need v-afc or greddy blue box? i am planning to run 6 psi.

 

i dont know what the greddy blue box is, but you need something like an msd btm to control your timing.

 

At 6psi you will be fine with the FMU, and you won't need to retard timing. Above 6psi and you will start to run risks.

 

It would also be a good idea to get an aftermarket fuel pump

 

why not jus tuse the blue box? it runs just fine with it...if you have a fuel compu ter.. trim it down to what you like

 

Yeah you should be fine @ 6psi.
I really recomend looking into some sort of actual fuel management like uberdata or hondata.
I ran a fmu for about 3 years it did it's job but I paid the price. I've since switched to hondata and my times speak for themself....fmu set-up = 13.5 @109mph
Hondata = 12.4@118mph..Granted I have more traction due to the drag radials but my Hp was up about 30hp with the same amount of boost.
