5.0lt efi
Hi All, I am new to this forum and have been building my G-Force Cobra it is running a 5.0lt HO but when I got the block there were no vacuum lines attached, I have worked out where couple of them go but there is 3 lines coming from the back of the Plenum, can anyone help out where these go. I have blocked the holes at the back of the block so I do not have to run the Smog pump. Also is there anyone else in this forum from NSW building the MK1 chassis.
Thanks Stuart |
Hi Stewart,
I'm building a Mk 1 G-Force too - the engineer is coming on Friday so I've been rapidly covering up the chrome bits (hope he doesn't read this thread !). I'm running a stock 351W and run the following vaccum lines:- Brake booster Computer (Autronic) Charcoal canister Fuel rail regulator Thats it ! pretty simple unlike most production cars which feed vaccum lines off in all directions. Hope this helps, Adrian. |
Hmmm,,,,I think you should also have a "map" sensor too.

The specific vacuum-hose routing will depend on the EFI setup (SD or MAF, specific computer, etc). Best bet is to get a Haynes, Chilton, or other service manual -- the vacuum diagrams are in there for each year. If you can't find one, let me know, and I'll dig it up for you.
Cheers, -Neil. |
Thanks for your replies, I actually found a diagram in FFR forum and it looks straight forward. I am running a BAP sensor and mass air flow not vss so that will be ok.
Adrian if you have any photos of your build and if don't mind I would be interested in taking a look, I still have a bit to go, so any ideas will help. |

Adrian I have posted some photos in the gallery which will basically represent the stage I'm up to.
Currently I am waiting for a computer and mass air flow and TFI dizzy and connect the fuel, lines and it should start. |
Welcome aboard Stuart. It looks like you are making some good progress there.
Cheers |

I wonder if it would be more efficient with a MAP sensor? I understand that is what the computer uses to determine "engine load". May also be primarily for altitude considerations (barometric calculations?).
What would a guy typically want for accurate injection computer decisions I wonder...... Mass Air Flow sensor for entering air volume. TPS (throttle position sensor, VERY important)! The O2 sensors for rich/lean air fuel ratio. Engine temperature for hot/cold performance. Crankshaft position (of course)! I wonder how the combustion chamber temperature is monitored? It seems THAT would control an EGR valve to reduce "peak combustion temperatures" to limit formation of NOX gases. And how is a "knock" or pre-ignition condition monitored? Which would result in an immediate retard on the timing. I love this "tech" stuff! :D Ernie |

Hi Stuart
I might be wrong but I thought with the new ADR rules you could not use the old ford 5lt unless its running on gas. Craig W:rolleyes: |

Thanks Stuart |

I have been advised of this from where I purchased the kit and I have also been told that new rules with RTA, that even running with gas will still make it virtually impossible to make it legal. I am planning to have it registered interstate where it might still pass. Otherwise I might have to invest in a newer motor. Thanks Stuart |
Stuart - any cars in Qld that are going for a 2003 Compliance Plate have to jump through hoops to get their car registered. Depending on who you talk to seems to determine the Emissions Level that you have to pass. I've spoken to engineers who will approve a 5.0L motor, and others who would require the new BA motor (or Chev/Lexus equivalent).
I wouldn't bank on being able to do the interstate tango when registering your car. It might be worth speaking to the transport department and engineers (hypothetically speaking -- without giving them your name), and seeing what they have to say... |
Thanks Craig
I have spoken to a mate who lives in Tas who seems to think it maybe possible |
I hope your car's ready in time for the Targa then - kill two birds with one stone :)
