405 4x4?

[adriches]

Did they do a 405 td 4x4? I dont think they did...
If not did they do a citroen BX td 4x4?

If u wanted a 405 td 4x4 would it be easyer to put the td engine in a mi16 say or convert a normal td to 4 wheel drive??
If Peugeot/citroen didnt make such a thing does that mean it wouldnt work??

I though Peugeot made the 405 4x4 in diesel form, but only as an estate. Might be wrong though. if they did, that would be your parts to throw into a saloon. There's going to be a huuuge hill of problems sticking a diesel engine into an Mi16 4x4.

It doesnt look like they did do a td 4x4.
Td engine into a Mi is a definite no no then.
So would the 4x4 bits from a GRix4 or Mi16x4 go on a td? What problems would there be?

[Admin]

Well the rear suspension of the 4x4's is totally different as it's lifted from the citroen so it self levells so you are going to need all the gubbins for that. You'll also have loads of trouble routing the drive to the rear as the normal fwd shell makes no allowance for the 4x4 transmission.
Obviously anything CAN be done, but it's going to be a labour of love. Goodness only knows what special parts youare going to need to manufacture from scratch to do it.

Do all the 4x4s have that suspension? Even the GRIx4 And Glx4 etc?

So what would be the problems with putting the td engine into an mi16x4?

The 405 MI 16Vx4 and GRx4 are both petrol models. In the UK the Citroen BX 4x4 was petrol only too. Both cars do not fetch hardly any money, as the transfer box is a week point and is about £1000 to replace. The 405 used a adaption of the Citroen hydropneumatic suspension on the rear only, electric motor driven I think. Fitting a TD motor to a GR would be the most sensible option as the 1905 block of the TD will match from the 1905 petrol unit. The torque from the TD unit however will more than likely blow up the transfer box fairly quickly. A scrap 405 GRDT would be able to donate a wiring loom to accom the diesel electrics.

The 405 is still made, including a rear wheel drive model, called the 405 RD, that is unique to Iran. 405s are still made in Egypt too.

So you would recomend an engine swap?
I wouldnt do it myself (not possible!) but id ask a pug expert i know. The engine and gearbox would connect up to the 4x4 bits ok? Any other advice? Recommendations?

You ask would I recommend an engine swap? I think the answer must be a resounding no! Apart from the fact that the Mi16x4 is an outstanding car in it's own right the, problems you will face will simply be too vast. If you end up suceeding in getting the engine in and firing you will probably end up with a bodged car that is full of niggling faults as you will not have access to any of the devlopment process that PSA would have carried out in order to make a production 4x4 diesel fit to sell, and will be plagued by endless minor faults and failures as parts you never considered, break under loads they were not designed to accept. A "simple conversion" such as putting the Mi engine into 205 GTi is well documented and has been carried out hundreds of times and yet most installs end up being trouble, goodness only knows what a bespoke conversion like you are sugggesting would end up like!

It doesnt sound cripplingly difficult to me. If you had a 405 MI16 x4 that one of the 205 boys had robbed the engine from it would make an interesting transplant. As you say the diesel engine lump would actually bolt in easily enough, and the wiring for a diesel motor is not too complicated is it, might have to change the engine wiring loom right over and the instrument panel. Much easier than if it was the other way round (pez engine into diesel car).

For me the only worry is as you say the diesel engine torque might overpower the transfer box. What are the relative torque outputs of the two motors?

Anyway an engine-less MI16X4 and a 405TD lump are not hugely valuable items, spend the cash and give it a whirl I say!

One thing to remember is the gear ratios will be totally wrong, with the slower spinning diesel engine, the top speed of the car will be slow !
