ITB question from a noob

[mmx005]

hi guys,

looking for a little advice to assist with the install of my jenvy itbs.

whats did you do for vacuume??? im paranoid about not having enough vac for my brakes in my daily dríven nb8a, does a bigger vac block volume = more vacuume??? eg a 500ml sizes block give more/better vac than say a coke can sized block?????

im guessing i need something with atleast 6-8 ports (1 for each trumpet so 4, 1 for my ecu, a BIG one for the breakes, 1 for the fuel reg, vac guage (some say uesless but atleast i know how much i suck :-P)) or maybe join 2 smaller ones together???

any advice (or pictures etc) will be appreciated as im a bit of a noob with this sort of thing.

cheers guys

I ran my brake booster off only 2 throttle bodies and I could not tell any difference than the feel with the old manifold. I would be more concern with the vac to the ecu, I had to move to tps, because the map reading was so unstable, to the fueling was all over the place
