Peugeot 207 engine swap?!

Post by Rosian Drashkov »

Hey folks,
I searched quite a bit the internet and couldn't really get somewhat of an answer to what I have in my mind right now...
So I have a 2004 Citroen C3 automatic that I smashed into a wall right before Christmas and totaled it. I've owned it since new and I know for a fact that the engine is in great working contidion.
As I was browsing through some cars I found an 08 Peugeot 207 for sale with a 1.6 blown engine which really got me into thinking wouldn't it be possible to put my 1.4 in it. I mean these Peugeots come with the same 1.4 so it should fit right? Does anybody know if the 1.6 gearbox will bolt on to the 1.4? And also do you guys think that the 1.6 wiring will be a plug-and-play on the 1.4 or it would have to be modified in any way?
I will be looking for any replies.
Thanks in advance.
Cheers

ECU would be different settings gearing would be wrong you'd need to change the gearbox as well. These jobs are good sitting with a cold beer a pig to do in reality

Thank you for the quick anwser! Obviously the ECU would be set up differently but would everything just plug in? And can it be reprogrammed to work on the 1.4 or I am gonna need a 1.4 ECU?

Not really practical as has been stated by Doctle.

One being a petrol and the other a diesel, it will have a completely different engine management ECU, gearbox, clutch, ABS system and just about everything else. Apart from all the mechanical mis-matches, the Engine ECU is specifically designed for the particular engine type - petrol and diesels have completely different ECUs and within these, different models of ECU for the different diesel or petrol engines. It won't work.

It's a non-starter to be honest. You'd be better looking for the same vehicle as your own, or just scrapping it and getting another one.

Ok, my mistaken assumption - for some reason I had diesel on the brain! :roll:

But the same principles apply, There were 5 variations of 1.6 Petrol engines on the 207.

The 2004 C3 had 2 types of 1.4 petrol engine (TU3JP & ET3J4) fitted and a 1.6 (TU5JP4)

The same 1.4 petrol engine used in both was the ET3J4 (1.4i 16V 90).

There was a TU3A 1.4i 75 used in the 207, but slightly different to the TU3JP in the C3.

So really, I would the VIN number of the 207 and the VIN of your C3 to be able to do a quick comparison of the the gearbox, clutch and ECUs etc to see what the differences are to help you further.

It will depend on what components the 207 has for the 1.6 petrol engine and comparing that to what you have in your 1.4 C3.

Well what I know is that the Peugeot is 1.6 120hp (the motor built with BMW) and my C3 is 73hp but I will update you on both VINs in a few.

I just went to have a look at the 207 and there's its VIN VF3**************[VIN obfuscated, can be read by forum staff]
The VIN on my C3 is VF7**************[VIN obfuscated, can be read by forum staff]

Obviously I can't go into the finer details - it would take 2 long - these are 2 completely different vehicles, but as noted - different injections systems, different gearboxes of course and different multiplexed networks I suspect. Different ABS systems too.

C3 TU3JP
AL4 with Final ratio: CP 21 X73
Gearbox differential 84
ABS Teves MK70
Sagem Injection


207 1.6 VTi 16V 120 EP6
5 Speed Manual
ABS Teves MK60 0
Bosch Injection
BSI +COM 2005 4-Position Ring

So more likely it is not going to be as straight forward of a job as I first thought. If that is the case I am probably not gonna bother but I am still curious if the engine mounts are the same and after all isn't it just the matter of air, fuel and spark? As you can probably tell I am not that competent when it comes to the internals of the vehicle and if your guys' answers were more positive about that case I was not going to be the one doing the job but a mechanic friend of mine. I just thought that it would be a pretty cool project and the result of it- a cool little town car.

Loom radiator exhaust ECU driveshafts could be different throttle pedal, doing an engine transplant is far from straightforward. I Once put a ford pinto into a vauxhall chevette. Looked easy utter hoor of a job

I mated an Alfa Romeo Giulietta 1300 twin cam to a Getrag 5 speed gearbox and put that into a Chevette!

These young chaps don't know what a Chevette was, they maybe think we are Americans! How did your swap work out? I had Weber twin 40 side draughts and the driveshaft was wobbly. Straight line fast cornered like a 2cv with a wardrobe on the roof
