Happy holidays to all! i just returned from my 2nd deployment in 2 years (NAVY). Its good to be home and ive followed the forum very little over that time. Im home for good now and am certain that i want to do a simple and custom FI setup. Ive read a bit on the engine managment forums but dont know what company id like to use for my engine managment. I want it to control fuel/spark/air. My setup currently is a mildly ported S5 motor in a SE with full RB streetport exh. with a (restricted for engine breakin) weber 45dcoe. I have a list in my head of what i think ill need different from my setup now to run EFI all the way. I dont want factory either. Thats all i can think of, so im sure i need some help and some pointers, i looked around for some books on the topic an was wondering if anyone has some reccomendations.

Custom TB w/ TPS
CAS from S5
i have SE injectors??
s4/5 fuel rail
I have MSD 6A

 

Tweakit throttle body
Megasquirt maybe?

 

does anyone have a TB size reccomendation? I mean i can use a TB off of a mustang/supra whatever.....right?

 

Why? Get the 51 size Tweakit setup, very nice

 

I agree, get the Tweakit setup. That's what I'll do if I ever get tired of the Weber.

The ITB setup is good, but fuel injectors placed directly in the motor (stock) is much better setup. thats why TBI is no longer used, its outdated.
