Default AU V8 Conversion - Parts List

After spending more days than i would've liked getting my V8 in and running,
I thought i'd save someone else the heartache by putting up a list of all the parts that were changed on the Fairlane to accommodate the V8.

I will break it up in a few sections so we can have a comprehensive list.

BRAKES
Shorten Vacuum Hose for Brake Booster - My 6 Cylinder Line had gone rock hard and needed replacing
IF you are installing a V8 i suggest uprating your brakes with better discs and pads, or even a retrofit of BF Brakes

STEERING
V8 Intermediate Shaft
Power Steering Lines - High and Low Pressure lines route differently
Power Steering Cooler - On a 6CYL there is simply a Loop Pipe, on a V8 there is an actual finned cooler
Grub screw or Replacement PSP Switch - to Block off and stop leaks from the Speed Sensor hole on the Rack
Length of 3/8 Hose - to run return line to the pump (Most Wreckers cut the hose)
Small Steel lines from Rack Body to Tower on Steering Rack (Mine got crushed by transmission on 6CYL Removal)

ENGINE
Water Pump - Easier to Replace while it is out
Engine Mount Brackets
Driver side Transmission Support bracket
Ford Steel Core AU V8 Rocker Cover Gaskets
Breather Line from Rocker Cover to Throttle Body
PCV Valve and Grommet

ELECTRICAL
AU V8 Engine Bay Loom - This runs from ECU to the Engine, Transmission, EVAP Cannister
Engine Harness - Please Be Aware that the Injector Plugs are to suit EV6 Injectors
EVAP Cannister
V8 Alternator Plug - You can either splice in your own connector, or use some half size spade plugs
Solenoid Plug (Unsure of name, Sits under the inner guard infront of passenger firewall - 6 CYL is different to V8
ECU - This will need to be reprogrammed to the car for Smartlock / Shield - Or if you run a QH - It can be disabled in the Programming
Ground Cables will need to be changed - You can pick up Ground straps of different sizing from SuperHeap or any Parts store
Starter Battery Wire - This is longer for a 6CYL, i pulled the excess up and changed the lug at the battery end once i shortened it
2x New 02 (HEGO) Sensors

FUEL SYSTEM
Fuel Pump - V8 Pumps have more flow, I believe these are the same as a VCT but i suggest a Walbro Pump - GSS340 with Installation Kit
Fuel Lines - V8 Lines are longer from the firewall forward
Vacuum Line - This is usually a package with the Fuel Lines
Vac Lines - From Manifold to Regulator

TRANSMISSION
Transmission Lines i believe are shorter on a V8 due to the box sitting further forward
Gear Shifter Linkage - V8 Linkages are Longer from the shifter to the gear plate - Roughly 1.5 - 2" Longer
Transmission Cooler - a Must if you install a Convertor

EXHAUST
V8 Extractors
Exhaust System from V8 Car - PLEASE BE AWARE Sedans are different to LWB - LWB are longer between Cats and Diff

COOLING & HEATING
Aircon Lines - From Accumulator on firewall to Compressor are Different (Lines mounted to guard do not require changing - But inline filter should be
Heater Lines - From Steel Lines on Manifold to Heater Tap
Heater Tap - This will require a Vac Line - The 6CYL One can be shortened by removing a section and installing the right angle connector to the end
Heater Core Lines - From Tap to Heater Core (Can use a BA 6CYL Heater Hose and cut it for two right angle hoses which will work fine
V8 Upper and Lower Radiator Hose - Please be aware that the Hose Clamp will need to be bigger for the water pump than for the radiator on the lower hose (Found this out at 10pm at night!)

FLUIDS
5L (or more if you have a larger pan) Engine Oil (Refer to Manual or engine builder)
15-20L of 95LE Transmission Fluid (For Autos)
2.5L of Green Coolant Concerntrate
Garden Hose
Brake Fluid (Always good to check the levels)

MISC
Cable Ties
Bolts - to mount the Power Steering Lines and Transmission Lines to the Crossmember
Band Aids
Music
Food
Drink
Leash - For the Dog that decides he wants to wedge himself between you and the car while on the creeper
Friend on Speed Dial who knows more than you
another friend on speed dial who never answers, so you can curse at him via voicemail (Kristo!)
Wrecker on Speed Dial
Access to the AFF Service Manuals and Wiring Diagrams
Never ending Bank Account
Hand Cleaner - A Lot of it
CLR - To wash your hair after working on transmission

That is one hell of a list and would put most off doing the conversion!!! WAY easier to do a V8 change in an E series compared to an AU ...... I have done my own below that should help anyone who thinks this is too daunting and would rather start with a cheaper E to get things going ......





BRAKES

STEERING

ELECTRICAL

FUEL SYSTEM

TRANSMISSION

EXHAUST

COOLING & HEATING

MISC
Cable Ties

Great list !! I'm doing my conversion in the next few months and this will be a great help.
I've got a few questions the 6 cyl run a 2 pin alturnator and the 8 runs a 3 pin connector which 2 of the 3 pins do you use on the V8 alturnator ??
Also in what way is the EVAP Cannister different to the 6 cyl i thought you could make the 6 cylinder one work for the 8 ??

If you check out the wiring diagrams,

it looks like the cables are reversed. I will get a Photo of my setup (Just using smaller spade connectors)

The Cannisters themselves look the same, so does the solanoid, but the vac lines are completely different, as the V8 ones have the fuel line closer and connect to a different spot on the engine.

I do have a set of Lines here from a V8 Cannister if you require, but it might just be easier to pickup a EVAP cannister from a wrecker as they literally slide in and out with very little effort required.

It was daunting, but after being halfway through the conversion, and having the 6 cylinder out and not wanting to put it back in i said 'damn the expense' and got it in.

There are still little fiddly bits todo but nothing too major!

Default Re: AU V8 Conversion - Parts List

Main Difference I know of is electronics,
The ECU will need to be flashed to a Manual Tune, Or you can use a Quarterhorse and do it yourself.

guys gday
Ive had a few AUs and fords in general over the years and just picked up a neat AU2 ghia as a weekend toy project thing. ,its got all the gear in/on it(leather,sunroof,tickford kit,low ks etc.....) i wanted except the 4.0ltr VCT engine,and have a V8 AU1 fairmont donor car.....
Amusing Ill use all the AU1 engine/gearbox and hardware pointed out in "the list"

Electrically Can I use the AU 1 v8 harness and ECU ? or is an AU2/3 XR8 ecu a better option for abit more poke stock for stock...before I tune it anyway...

Before it goes in Ill fit a better performing cam,extractors,exhaust,inlet manifold and either flow these stock Au1 heads or look at a better off the shelf head type....?????
Does the car require engineering in NSW for the conversion? or just a blue slip and rerego it...?

Ill post some pics up tommorrow when i pick her up.....thanks guys

@V8Falcons You will need to use the AU1 ECU as the Injectors are different on the S1 motors to S2/3.

Another thing to watch out for is the fusebox harness... Mine was missing the power pin for the passenger side Oxygen Sensor!

@Lost the plot - Not sure on the spacer.. Maybe try a wrecker for another tailshaft?

Hi, First up, great thread! Exactly what I was looking at doing! Just wondering though, how do I go with the legalities for this? Will I need engineering certificates? Or just a bolt in job, and updating engine numbers on licencing papers?
All help will be appreciated

Default Re: AU V8 Conversion - Parts List

hey John,

Here in sydney, All the car needed was a Blueslip.
They checked I had used all the factory parts, had uprated brakes and steering.

Identity check on the motor and that was all.
If it is done with parts from that Car with a factory V8 Option, there isn't any major hurdles.

Nathan

Default Re: AU V8 Conversion - Parts List

Nathan, thank you so much for making up this list. It has been my bible while preparing to do my V8 conversion.

I'd like to ask a few things about it please. Sorry if some of the questions seem silly but I am learning everything as I go.

STEERING
Grub screw or Replacement PSP Switch - to Block off and stop leaks from the Speed Sensor hole on the Rack
^ Is this sensor no longer used when converting to a V8, or is there another sensor?

ENGINE
Engine Mount Brackets
Driver side Transmission Support bracket
^ Were the engine mounting brackets and trans support bracket changes technically the only things required when an engine is all fine?

ELECTRICAL
Solenoid Plug (Unsure of name, Sits under the inner guard infront of passenger firewall - 6 CYL is different to V8
^ Did you ever find the name of this?

ECU - This will need to be reprogrammed to the car for Smartlock / Shield - Or if you run a QH - It can be disabled in the Programming
^ Will the car start and be drivable until flashed, just no security?
Ground Cables will need to be changed - You can pick up Ground straps of different sizing from SuperHeap or any Parts store
^ Is this a cable from engine to battery ground? (I forgot to look tonight before asking.)

FUEL SYSTEM
Fuel Lines - V8 Lines are longer from the firewall forward
^ Can they be extended using longer fuel hose instead?
Vacuum Line - This is usually a package with the Fuel Lines
^ Can you please explain a little more about this? Is this to the Evap?
Vac Lines - From Manifold to Regulator
^ Would you please be able to show a photo of this? (I can't be sure which it is.)

TRANSMISSION
Gear Shifter Linkage - V8 Linkages are Longer from the shifter to the gear plate - Roughly 1.5 - 2" Longer
^ How is this accessed? Does it come out the top after the trans is dropped out? What if removing both engine + trans together?

Was there anything else you think would be important? I saw your note about the oxygen sensor pin, is it just literally adding a pin into the fuse box harness to enable it, or more involved? Are the two oxygen sensors part of the V8 engine harness?

I am guessing also:

Cruise and throttle cables different lengths?
V8 dash (for rpm)?
V8 driveshaft

Thank you!

Thanks for the feedback Utu13.

My best advice is to do some reading in this very area, or moreso the Workshop builds one level down. Mods can be personal, so it really comes down to what you want to do, what your skill levels are and do you want to do it yourself. There are plenty of threads that have shown varying levels of mods, some done at home and some paid for.

Research is king. Sorry if you where looking for an easy answer.

Cheers
Stu
