Looking For Info On Interchangability Of Relay Engines

[marcus88]

Hi guys, i've had a long look through the forum and I can't find any existing posts relating to this, please stop me if i've missed something.

I've got a Citroen Relay 2005 with a 2.2 HDi engine. The engine has given up on and I want to replace it. I'm looking through the internet and finding a lot of engines from different Relays, I'm wondering which engines are possible to interchange with mine.

For example, could I refit it with an engine from a 2004 Relay, or from a 2005 Relay but a 2.8 engine ... ? What are my options?

Obviously I've clueless and any advice is useful.

Welcome to the forum.

 

A quick look on ebay searching for 2.2 hdi engine came up with this http://www.ebay.co.uk/itm/like/252779463802?lpid=122&chn=ps&adgroupid=13585920426&rlsatarget=pla-75952154106&adtype=pla&poi=&googleloc=1006876&device=c&campaignid=207297426&crdt=0

 

For alternative engines, I can not help much other than point you at the parts diagrams to see which parts are common for the different engines and which other parts you may need for a different engine to fit - you could also look at other cars with your engine. As well as the engine you might need the ecu - if so you might also need the bsi/keys for the imobiliser and the radio to match the ecu.

If you are fitting a different engine (ie 2.8 instead of 2.2) I believe you will need the ecu. The injectors on Renault engines are coded by the ecu so you would need someone with "canclip" to programme them for you,

 

I have anumber of renaults, most of them Megane. Two of them look exactly the same but one has a 120 BHP engine and the other has a 130BHP engne, both engines are classified F9Q and you would think that swapping them would be simple, but it is not. Even the pumps are individually matched to the ecu.

Also the 2.2 has two different engine types, the adjustable cam shaft type and the non adjustable cam shaft type. I believe the engines are interchangeable but obviously they have different cam belts which you would be changing as a matter of course anyway.

 

If you take my advice you will go for exactly the same engine and, if they will come out (most of them dont) swap the injectors over and the pump from your old engine, that way no programming is necesarry.

 

(HINT _ Spraying lots of release oil onto the injectors and using a spanner on the machined flats of the injector, start tapping it gently forwards and backwards, takes a long time but if you are lucky you will start to get movement and eventtually extraction.)

 

You would be fitting a new cam belt anyway so no hardship to swap the pump, it is timed electronically so you dont have worry about timming marks.

I forgot to mention, to do the timming belt (cam belt) on the 2.2 you will need a crank pulley "Puller" to get it off and you will also need a belt tensioner guage that measures in "Seems"..

 

Another thought is that if you were to try to go for a 2.8 instead of a 2.2, I do not think the gearbox would match up and if it did, it would probably not be man enough for the extra power.

 

Not trying to put you off, but, best you are aware of what it entails before you tackle it.

 

2.2 engine code 4HY (DW12 UTED)  77Kw @4000 rpm

2,8 engine code 8140.43S                 93Kw @3600rpm
