Aye lad, the whole 1.7 clutch assembly (clutch plate, cover, and thrust bearing) are used. Forgot to specify! Cheers lad.

I know this aint quite done yet, but this is very useful already:D

Epic thread!!

cheers lad! Thanks for reminding me to finish it! Job for next week I think.

SECTION 4. ECU/ELECTRICAL CONNECTIONS, MAP SENSOR AND FUEL RAIL

As previously stated, I am using Adam's (340GLT) loom, so I will just be showing how and where to connect his version. I will not be showing you how to make your own. Adam's loom came ready labeled, so all I had to do was find the right connection on the engine and effectively plug & play.

1. INLET SIDE OF ENGINE

Connect the large ECU plug to the ECU. The loom connections will start from here.

Below, the main connections can be seen that connect the volvo loom to the stripped clio loom. (1.) Connection 3 is a diagnostic port, and connection 4 is taking a rev signal to a rev counter I have installed. You do not need this if you don't want to. Some 340's are lucky enough to have a rev counter already installed. I was not one of these people.


From the 2 pin connector labelled Ignition coil, there should be 3 wires coming from it (pink, yellow, and black). These connect to the grey, blue and orange wires from the volvo loom respectively. The other plug from the ignition coil in the middle needs to be earthed (2.).

The yellow wire from the actual clio loom is the ignition live (this should come labelled), and needs to be attached also to the yellow wire from the ignition coil. After these connections, they should look like this.


The injector plugs are the four plugs that look identical. The the plug with the shortest length of wire goes to the plug closest to the bulkhead, and so on. You'll know if one of the connections is wrong, as you won't be able to get the rest on. (Injector locations circled in red)


Connect the air flow metre connector (1.) and TPS (throttle position sensor) connector (2.), located here (TPS connector hidden in the picture slightly by the loom):


The fuel tank to fuel rail connections (1.) are shown below, as well as vacuum for the brake servo (2.), fuel pressure regulator vacuum (3.), and MAP sensor (4.).


Location 1. shows the Inlet and return outlets of the fuel rail.
Location 2 shows the solid line the goes from an outlet on the inlet manifold around the engine cover to the brake servo. (indicated by red arrows)
Location 3 shows the FPR, with the white arrows showing the routing of the line from it's vacuum port to the FPR (part of the pipe is hidden beneath the servo line in this picture).
Location 4. shows the location and connection of the MAP sensor. The yellow arrows indicate the routing from a vacuum port on the inlet manifold to the sensor. (The actual sensor can be located on the bulkhead if desired, or anywhere else, however mine is here due to the short length of hose I had left from the build.) The sensor connection to the loom is the large 3 pin green plug, which should be labelled "MAP".

The image below shows the connection location for the air temp sensor, on the end of the inlet manifold (1.) Outlet 2. is an un-used vacuum port, which can be used for the volvo econ gauge if you have one, or it can be blanked off.


2. EXHAUST SIDE OF ENGINE

The starter motor connections are as follows. The large red cable is the power to the starter, attach the cable loop to the positive starter bolt, and do up the nut. (1.) The yellow/blue striped wire previously used for the volvo ignition switch needs to be cut into (2.), and using a 3 terminal connector, connected to both the long black wire (2.) from the clio loom (signal to the ECU to tell it the engine is being turned over) and the rest of the original yellow/blue wire (this is done because if the black wire is connected directly to the starter motor, the wire can overheat and melt. The thicker striped wire prevents this).


Also, make sure the starter wires are clear from the exhaust manifold and downpipe.

The engine is earthed using the original braided volvo earthing strap, and is attached to the block in this location.


Make sure to insulate all connections before you connect the battery terminals, and when you are satisfied all the connections are correct and secure.

What starter motor should I run?

The one with the F7P/R engine. Your 1.4 starter IS COMPLETELY DIFFERENT and specific to that engine.

What about 'classicswede high torque one on his sight?

The 1.7 and 16 valve starters are the same. The one on my sight is slightly uprated with higher cranking power.

I'm planning doing this over Christmas, been stock piling parts
can you not just use the whole 1.7 gearbox instead of changing parts around?
Would make it easier but not a huge worry, don't mind the extra work

You have to use the complete 1.7 system

gearbox is at the back of the car fella. You dont have to touch it. Detach the prop and its all front end stuff like the bellhousing, sump, engine mounts etc.

Sorry to dig this up since Nov/Dec i just had a few questions.

I was looking to either go F7P OR F7R.

I have been looking into it and i have seen a few engines available but am unsure which one to get.

There is the F7R from a laguna but as i have read they seem to be difficult when it comes to ECU Loom conversion.
Other then that there is the one from the clio williams engine but as there was only some silly number made it seems like it would be impossible for me to source one.

then theres the F7P - I have seen they come from either the renault 19 or the clio 16Valvers.

My question here is what sort of clio can i get one out of - as in what year am i looking for.

Ideally i would want to go to several scrapyards and take an engine from one of those or look for an engine for cheap.

All the engines i seem to see are around 300 mile round trips and are big money in comparison for me driving a 50 mile radius to over 30 scrapyards.

And then when it comes down to the loom conversion - Adam hasnt been on since November so not sure about whether i could get one from him. Is there anyone else who does them?

If anyone could point me in the right direction that would be great.

FYI i have a Volvo 340 - 1.7 C Reg .

Thanks!

Theo


*Edit i have just done some searching - it comes back to suggest what f7p and f7r are installed in.

Last question would be - what are the capabilities and limitations with a F4R engine.

I enevitably would be putting it on motorbike throttlebodies rather then fuel injection.


Thanks!

Awesome thread! this has some very helpful information, thank you.
