Take off all the vacumn lines, but don't bin them just yet. You'll need a vacumn line from the altenator to the brake servo and a tee off this to the front axle. You'll also need a bit of the disguarded piping to go from the boost compensator to the intake manifold.


... and what he said Very Happy

If the 3.1 is anything like the 2.8 for vacuum pipes the only one engine wise you "need" is the pipe that runs from the inlet to the top of the fuel pump.

If however you still want to keep the quick warm-up, and EGR facilities you need the wiring for the solenoids and the vacuum system for the two actuators, fuel pump throttle adjuster valve thingy and EGR's as well.

Thinking at the moment tnis poor chap is confused enough between 2.8 posts and 3.1 and other mods
lets just guide him into getting a 3.1 standerd fitted so ne can get jup and running again this thread is reading like rocket sience please dont ta;e offence at this  but i you read the Thread through its a proper nead scratcher

The 2.8 and the 3.1 is basically the same engine. What works on one will work on both. The conversion process is the same.

Hi all,
  I'd just like to thank everybody who has posted so far, I read most of the threads in the general and engines forums and I've have learned a hell of allot from them. After this project is over I should be able to answer a few questions myself! It really is a great online community, two members have given me there contact details which I really appreciate. (I not going to annoy them until I run into problems with the wiring which by the looks of it is a certainty!) But I will post what I run into here, it may help someone else down the line...

So just wanted to say thanks to all....

Well I've progressed a little further,

I fitted the 3.0 adapter plate to the 3.1, 4 bolt holes matched up so I didn't try to drill any extra. I fitted the 3.0 flywheel and clutch. I left the 3.1 spigot bearing inplace I figured that the 3.0 spigot bearing is so far forward in the fly wheel that the input shaft should to hit the old 3.1 one (hopefully I'm not wrong on this).
I had to grind down a locater pin at the top as it was rubbing against the larger 3.0 flywheel.

I fitted the 3.0 filter and housing to the 3.1 engine, the water pipe at the back of the cooler is a different diameter to the original, I had to make an adapter to bring it up to size.

I have a few questions that I'd like to get figured out before I try to put it in, hopefully the pictures I've taken will show up

<img>http://s1225.photobucket.com/albums/ee397/diytrop/?action=view&current=stats.jpg</img>
What are the 3 sensors number 1, 2 and 3 in the above photo for?

<img>http://s1225.photobucket.com/albums/ee397/diytrop/?action=view&current=pump-inj.jpg</img>

The 3.1 engine comes from a 94 and has no security gadgets on it,
This is a view of the injector pump,

There are 3 different connectors coming from the pump.

One at the back marked 1 which is a single wire.
Two comes from the righthand side of the pump as you look at it from behind and is marked 2 in the photo, it has two wires
Three comes from on top and is marked 4 in the photo,

What do all these wires do, do I need them all to work?

The last thing on this photo is the pipe marked 3, where do I connect the other end of this to?

<img>http://s1225.photobucket.com/albums/ee397/diytrop/?action=view&current=flywheel.jpg</img>

This is a pic of the flywheel, when is the fork engaged with the release bearing is this after the gearbox is bolded to the engine or does it have to be lined up when they are being mated?



<img>http://s1225.photobucket.com/albums/ee397/diytrop/?action=view&current=oil_press.jpg</img>

And lastly is this the 3.1 oil pressure switch?


Sorry for such a long post hopefully someone might know a few answers to these..

Many thanks...
