3V 5.4 Swap In Progress Questions

zinc-vert02 · January 8th, 2012, 08:31 PM

ok so some of you know that im working on my 3v 5.4 swap right now.

what i need to know is if i can wire up the 3v fuel pressure sensor on the fuel rail to work on my 2v harness...

also nee to know if i can splice the 3v IAC plug onto me 2v harness and use the 3v IAC sensor ( will make using the super charger elbow easier

also, the rousch charger has a small blax box under the lower intake that has a 2 wire plug on it and has a couple vacum lines going to it that i need to know what the two wires are for...

any help on these questions would be fun

number1gt · January 8th, 2012, 08:35 PM

Im sure you can splice the in no problem but as far as that last part...good luck wish I could help

zinc-vert02 · January 8th, 2012, 08:38 PM

yea im jsut hoping they send the same info to the ecu like the 2v sensors do

number1gt · January 8th, 2012, 08:47 PM

Did you get the whole kit to do the swap?

zinc-vert02 · January 8th, 2012, 08:50 PM

i got the entire engine,

5.4 3v out of the stage 3 f150 witht he twin screw roush charger,

then i got it home, pulled the oil pan to find out its fulyl built lol

number1gt · January 8th, 2012, 08:57 PM

You luck bastard

how much did you pick it up for? I know there is a company that sells everything you need to swap a 3v in for 900 or so

zinc-vert02 · January 8th, 2012, 09:21 PM

i paid 2500 for the whole thing, and the lower end should be good for more power than ill ever make

number1gt · January 9th, 2012, 03:51 AM

Then more boost is a must

94racing · January 9th, 2012, 09:16 AM

i think its logan motorsports.
the sensors should be the same other than having to splice them. if they dont work you could probably make a fitting to make the 2v sensor fit but i would much rather slice the wires. as for the 2 wires it could be something for you to hook a gauge up to.

i know the guy that i got my front valence off of just wired his gauge to the supercharger while i was picking up the bumper.

i figured out the two wire plug is for the EGR, so its not needed

wrong, 3v's dont have egr, the cam phasers retard and advance the cams to meet emissions.

Its under the intake? are there metal rods attached to it? almost sounds like the imrc box to me

zinc-vert02 · January 9th, 2012, 10:51 PM

the engine does not have the intake flaps on it. so idk i they where taken off then the super charger was put on or not

so i guess the mystery remains on wtf that plug it for

86er · January 9th, 2012, 10:54 PM

prob the old imrc box. It sat/sits at the back/under the intake

zinc-vert02 · January 9th, 2012, 11:09 PM

yea thats right where it is, im hoping thats what it is, at first i thought it was for the small throttle body looking thing thats in the super cahrger, but from what im learing that is the vacum operated boost contoller of some sort

sorry im very new to roots stlye super chargers

zinc-vert02 · January 9th, 2012, 11:10 PM

thanks bro

86er · January 9th, 2012, 11:11 PM

that sounds like the boost bypass valve on your current set up, lets boost escape when cruising. Are the vacuum lines a colored hard plastic or black. Small square connector or a flatter looking connector?

zinc-vert02 · January 9th, 2012, 11:12 PM

86er, do you know if i can runt he 07 style fuel pressure regulator on my 2v harness? the 07 style has four wires to it and the 2v has 3..

also need to know if i can use the 07 style IAC on the 2v harness...

any help would be awsome!

they are hard red lines, one goes to the intake wlbow behind the throttle body and one goes to the acuator fort he bypass valve

its not a regulator, its a pressure sensor, youd prob be better off finding a way to adapt the 2v one.

07 doesnt have an IAC. It only has a TPS. The DBW handles the idle/throttle opening that the IAC use to do on cable driven tb's

zinc-vert02 · January 9th, 2012, 11:30 PM

so i need to figure out a way to use the 2v IAC on the 3v elbow...
