Don't have any pics of it but I moved the radius arm mounts back 15mm and spring mounts back 10mm and now its all looking sweet as.

Iv got the shock mounts with me and will get some crusher tube so I can mount them onto the series chassis
Image

Iv also got the bump stops which need the old disco chassis cut off them. Might need a packer between the bump stop and the chassis so the wheels don't hit the deck when flexing but i'll deal with that when I get to it.
Image

Im back in Christchurch now so there won't be another update for a while but the next one should be a big one as I will be in central for a week or more instead of a weekend.

Right then, back in central for about a week and a half and the aim is to get the front end in...

Iv measured up the front end to ensure I get the right castor angle and to make sure diff will sit in the center and every other measurement under the sun. I also took note of the angle of the spring mounts on the diff and with no weight they are angled forward quite alot...

Here are a whole lot of random pics of the front end. Im off to pull it to pieces now. :twisted:

You can see in this photo how much of an angle the springs are forwards with no weight.

So now iv dismanteled the front end. Cut the engine mounts off because they were easy haha. There ready to go on once the front end is under it. Then I decided to move the outriggers forward so it was easy to mount the front radius arm mounts. I also needed to cut 50mm off the bottom of the outriggers so the front radius arms could pass under them and not hit while flexing.

Pics

What the left side outrigger looked like for a start.
Image

This is the rightside outrigger after removing 50mm off the bottom and moving it forward.
Image

Once it was tacked on it was clear it was going to need a gusset. So thats what it got.
Image

Image

Im also planning to put a gusset from the radius arm mount to the outriggers for additional strength.

Iv done both sides and tomorrow I'll start gassing off the spring and radius arm mounts off the disco chassis and get them ready to go onto the S2 chassis.

I cut the spring and radius arm mounts off the disco chassis and cleaned them up. Tacked on the front spring mounts and sat the diff under it and it looking not to bad.

Its mint how photos make it look like you have done more than you actually have haha

Image

Image

About where the radius arm mounts will go.
Image

More shit that I have to cut out so I can put in a new front cross memeber and the disco engine mounts

I cut all that stuff shown in the previous post. Finished up the front radius arm mounts. Sat the motor where I wanted it to be, marked where the engine new engine mounts were to go, tacked the engine mounts in place, put the motor in, put the bulk head on and put the deck on.


Motor sitting in place
Image

Image

Image

Image

Image

So where I have the motor sitting at the moment, the oil filter is dangerously close the the diff head.

At the moment the gearbox is sitting on the old series gearbox cross member and once the disco gearbox mounts are in (series gearbox cross member removed), the back of the gearbox will be 2 inches lower, which will lift the oil filter about half an inch.

This wont be enough. So I'm looking to possibly use the oil cooler lines to mount a remote oil filter. However there will probably be a valve to stop flow to the oil cooler when it is cold so im not sure if that will work...

Image

The deck sits about 60mm higher at the back and the rear springs are far to stiff. If I was to run the disco rear springs I think there would be about 50mm of down travel haha. Im not sure what springs to replace them with does anyone have any ideas?

Image

I have also pulled out the disco wiring loom and have brought it back to chch. What a mess!

Looks good. Just today I got my Disco V8 same as yours going in a project. Its pretty straight forward, there are only 4 wires needed to make it run.

Re: V8 Land Rover project

Any pointers of what those wires are? Even the colours of them because im picking they will be the same. I was also wondering if with just those four wires if the computer runs in "safe mode" which I think means it will just use more gas.

Heres the entire disco loom less the engine loom because I cut it off :oops:

Image

I didn't realize that the engine loom was separated from the rest of the loom so nicely. Where the loom has been cut comes pretty much directly from the engine and the rest of the loom (the one on the ground) as far as I can tell, is separate.

Image

So at this stage im thinking of getting some new crimps (if you can buy them) and rewire the EFI computer plug to the engine loom. The engine loom has enough length to mount the computer on the inside of the firewall, wire the plug onto the end of it, get the four magical wires that make it go wired up and hopefully it will run...

Image

Image

Or if it comes to it I will just join the bloody thing :roll:

Either way, It would be great if I knew what those four wires are...

At this stage I can't remember without going out and having a nosy. I just remember the black on the coil bit going to power, caused me a headache and oh having the fuel pump going the right way :oops:

I'll have a gander later on today for ya and see if i can see whats been wired where.

cheers

Yes, got to to shoot to work now but will be in touch later today. My loom was cut like yours, looks like the same place as it went through the firewall. Just join them all together and you should end up with two connectors - a white one with lots of wires and a brown one with about 7 wires.

My program appears to not be opening.

Image

This photo here - just about where you cut it there is two connectors that you need, they are the ones to connect. So the loom you have cut, most of the wires go between the engine and the ECU, it is a simpl case of joining them together, I had to solder all mine together.

Image

It is good if you have the whole loom as I did, you can then use the factory plugs. So 1st thing is to join the loom to the motor.
Then you will identify the plugs I talk about a white one and a brown one.

There are two relays you need are one to work the fuel pump and one 'main relay'. They are already in the loom and you can see them in the photo. They are the silver relays, the two yellow and one green one are to do with the air conditioning.

The fuel pump relay needs power from the exterior fuse box. Thats one wire.

That main relay needs power from the exterior fuse box. Thats the 2nd wire.

The Fuel pump relay has an 'out (87 pin) that goes to the fuel pump

The Starter wire needs run

Then you need power for the ECU, this comes from the key when it is in the "on" position, the one that controls the coil etc, so when you turn the key off, it turns the motor off! This one is generally straight from the key and is also fused.

Those are the basic wires, I'll try take some photo's tomorrow so you get the idea.

I do know some models earth differently. I have one here with multiple earths and another loom that is one earth with a big junction box. I did alot of reading to get mine going.

Hey thanks, very good info.

Heres a pic of the top of the EFI unit.

Image

its a bit hard to read but the numbers are:

Top, left to right:

AMR3242

14CUX

80505A

and the Data Code is: 0896

Those were the only numbers I could find.

The white plug and brown plug you are talking about. I figure they were inside the engine bay? And what your saying is once I find those two plugs, using them, I supply ignition to the EFI unit via the "main" relay. Should I supply ignition to fuel pump relay or just a fused constant 12V?

Also, there are two silver relays, two yellow relays then the single AC relay. The two silver ones look like fuel pump like you said because of the heavy duty wires. I was just wondering why there was two for the fuel pump and two for the "main relay" and how you dealt with that when you supplied them with 12V.

I do have all of the loom so I should be able to use the the factory connectors.

A close up of the two plugs would be great then I could get some idea of colours. It sounds like its the same loom because mine also has the multiple earthing points.

Cheers, Pete

Hi Pete,

I hope you are not in a hurry as I have not had a chance to get down to the shed and am now away with work until later in the week. I should be able to tell you what you want over the phone if you want, 021 775180, Glen.

The two plugs can just be seen on this photo of mine in the bottom right. A brown and a white.

No i'm certainly not in a hurry Glen. Im planning on having the truck finished around June next year. I had a look at the wiring diagram which mike PM'd and have labeled all the wires where it has been cut ready to join it. I also identified all the relays and all going to plan, it shouldn't be to difficult to run those additional wires to the plugs you described. Just from the pic's you put up I can see the purple and white wire for the fuel pump. How did you go about joining your oxygen sensor wires, as they are co-axial i suppose you would call it, making it a bit more tricky...

Been a while but to show im still working on this old girl.

Image

Im after a rangerover steering column so if someone has one lying around Im after one.

Image

Image

Iv cut the front bit down and moved it forward an inch and im going to move the bonnet forward an inch on the hinges.

Iv got the landy in dunedin at the moment and want to swing it past the cert fellow before I weld everything up. I want to get the steering and brake pedal and booster and a steering aligment done first.

I brought these 32 x 9.5 x 16's simex's.

Image

I tride some 15x8 will buckshots on to try get an idea of what off set rims I need.

Image

Image


Photo's dont show it that well but they stick out a good 3.5inches. I think I will need to get zero or negative off set rims...

More photos of progress.

Panel beating has been slowly progressing.

Steering shaft is sorted. It was made out of a solid shaft with matching splines for the steering box and top universal.

Dual fuel tanks have been fitted. Coated with POR15 fuel tank sealer on the inside to stop any pin hole leaks.

Front radius arms are out getting castor correction bushes pressed in.

Where's the radiator going to go? I suppose thats why when ya see series rovers that have been converted to V8 they have defender/stage 3 front ends on them.

I did when I tried on that buckshot but didn't get a photo. I should have the tires on the truck in the next fortnight. I need to put them on before I do the bump stops to make sure I won't munt the guards the first hole I go through..

Yip but series 2's and 3's look cooler so the radiator had to go on the back. I'm planning on mounting it inside the roll bar down low against the back. I'm going to try the stock disco radiator with some serious fans with a wire mesh guard around it to stop it getting munted. If it it overheats then ill splash out and get a massive radiator.
