no... that would be far to easy ...
and keep in mind, these numbers are NOT LR numbers BUT VDO numbers...
what i now "know" (can find), is this... LR seem to have changed the whole fuel system (HPFP, presure rail's AND injectors) when they added the DPF for EU4 My '07 models
BUT Jaguar, did achieve EU4 with the same HPFP pump and Fuel rails as LR used for their EU3 system..
and they did it on the S-type from My'04 till Early '08
that is why the EGR's on this engine are from a '08 licenced plate (can be a MY07) are the EU3 "model" on a LR.. as are the HPFP and fuel Rails...
the injectors although seem to be different on a JAG by standard... (all JAG EU3 or EU4 are different than on a LR either EU3 or EU4)
i have to compare the wiring loom, but it looks that these are also the same in colorcoding and wiring, as a EU3 LR maybe the connectors to the car are different, as said have to compare that still
if so, very easy swap...
Exhaust manifold's , turbo , airco compressor, dipstick, oil pan&frame and Fan connection ..
nothing on top..Best regards

We’re all super keen for this to progress and see if these cheaper alternatives are worth the bother, so far...they seem they are!
Keep up the good work.

Thnx...
this replacement is rather common Ofcourse. disco mikey did it more then 10 years ago from what I read.
BUT I couldn’t find almost nothing regarding What to exchange, other than ALL the ancillary’s,
Because.... no exact data..
And if everything else on your old engine is in very good nick, not the biggest job and most difficult job to do it all, but why not keep the youngest and “best” parts if possible...Best regards

Well, I did not take that final decision, but am leaning towards body off..
What I hear/read, it takes the same amount of time in total and body off is easier to work
I simply do not have the time to do it completely myself, since I have a busy Motorcycle shop and the spring is coming... so I take care of the preparation/engine work myself but he transplant itself is in a fully equipped workshop , so body off not a problem I presume...Best regards

another difference of the EU3 to EU4, at least on discos, i the location of the fuel pressure rail sensor. on the old one is vertical to the the rail while on the later is parallel to the rail. i don't know if that will help.
on the other hand once you remove your old engine wouldn't you be in position to compare both fuel systems? that wi tell you if you need to interchange HPFP and lines.

Thanks for your input...
As a did wrote earlier.... it is not a question for me IF I have to replace the fuel parts... on a EU4 Jag s-type TDV6 they ARE the same as on a EU3 LR TDV6 (except for the injectors who are by default different in VDO part numbers as LR, but I keep them in place I think, first I will have a try with them...as Disco-mikey said earlyer, the EU3 system works fine with EU4 injectors from a LR, so why should these do not the same )
You can clearly see the HPFP model/type and fuel pressure rail/sensor on here same as LR EU3 (but on a EU4 jag engine)
Regarding the wiring loom , last night I was thinking, it should be different, hence the twin turbo on a JAG, so it must be different...Best regards

Hi pete
where is the second MAF located on a Jag? on the jag engine i have here, i can not see any difference in sensor's at first glance.. (in the air/inlet part)
and "port opening wiring solonoid" what do you mean by that?Best regards

The MAFs are on top of the air filter assembly. Which will be left in the jag! But the wiring will be present.
The port valve connection is ontop of the inlet manifold at the back. They are unconnected on the LR.
The valve is on the front belt cover

MAF, ah yeah.. you are right.. was too focused in the engine alone
BUT... the port valve On the inlet manifolds ... you mean the “vacuum” valves? On the back? The one’s who are connected on the jag engine with a tube?
Edit.. 24/02/20 misunderstood the message from peteK.. so rephrased it..Best regards

This week I bought a small block from a LR
Engine is Upside down on the pictures 8)
Two reasons why I bought it: it was cheap, has a good crank (I hope) and the most important reason, the ladder frame and sump, fan carrier, exhaust manifolds etc. needed for the swap... are all there! so I can build up a complete engine ready To LR spec before I start the actual engine removal process from the D3 this way I am saving expensive workshop time because no paid working hours for swapping engine details (exept for turbo, alternator and aircopump, but that is rather quick work)
The good crank can be used to build up/repair the original engine later on...Best regards

This weekend I sorted and did take a picture from some of the LR specific engine parts (from a extra donor engine I bought rather cheap since that one seems to have a good crankshaft) who need to be changed on the JAG S-type engine... before you can replace the starter, turbo, airco pump etc..
I planned To bolt them on After I do change the main bearings and big-end shells (because it is rather easy now)
Although I have to loose the pulley bolt first.. before I can change the oil pump ...
And believe me that is not easy on an engine out of the motor/car .....Best regards

The LR specialist garage that MOT's my car would say don't even think about the Jag engine.
They have tried to do this once and it turned out to be to costly to be economical.
that was not just on the Labour but on the new parts required. You can only make it economical if everything either comes from the Donor or 2nd hand Ebay.
