Hooniverse Asks: What Would You Do With This Lonely Citroën V6?

It’s a lovely problem, isn’t it? Certainly, it’s more likely for a car to lack a working engine, than an engine to lack a fitting car. But that is the issue here, faced by my friend Lauri: he has a perfectly fine, leftover PSA 3.0 24-valve V6, but nowhere to put it. He ended up with the engine as his otherwise impeccable 406 Coupé suggested another transmission could come in handy, and the powertrain was dropped in his lap as a pair in a deal he could not resist.
So, which car would most benefit from the addition of over 200 French horsepower in V6 form? Hilarious mid-engined shopping carts come to mind, but surely there are other options. The sky is the limit!

  1. Boring option: break it down for parts, either to sell, or to use for spares when they go wrong on his runner.
    Fun option: swap into Fox Mustang with dead or 4cylinder (nearly dead) used to live, head to LeMons.

    1. No. What that Mercedes W201 needs is a completely bolt in, no mucking around with electrics W124 320E 3.2 litre bottom end bolted in,or, put up with a little bit of wiring,(but less than you’d need to put in a French engine) and put in the whole 24V 3.2 M104. or if you can get one, an AMG 3.6 to make a 190E 3.6 24V, plus of course the 6 speed manual gearbox from a C250D. Absolutely heaps of information online as to how to do it

  2. Antti, I’m more than a little shocked your answer isn’t shove it in a Delorean.
    Personally, since I have a small hatchback anyhow, shoving it in the backseat is the best answer for me (especially if I went twin-engined to get 300hp). Otherwise, I’ve been wanting to make an engine wine rack or coffee table or something for a long time, so that, and other assorted car part household items.
    Going really weird, find like the one remaining Eagle Premier, and give it a nice little power boost.

    1. I have a quite unnatural affection for the Eagle Premier. In white with red leather interior please.

      1. That’s rather interesting. Do you happen to have a link to this car, preferably one that shows the engine bay in some detail? I’m not finding anything on it, and would love to see how they accomplished this.
        I have an idea for a front-engined R5 with the PRV motor and gearbox from an Eagle Premier; this A310 has my mind becoming very interested in the 3.0 V6 for that project.

        1. I have corrected the spelling for Reo Motors, the company that kept Renault alive in NZ when there was no official importer, after the Rainbow Warrior bombing by the DGSE.
          That is a stock picture of an Alpine chosen because it is the same colour as the one I saw converted. In those pre-internet, pre-cellphone camera days, much was left unrecorded, I saw the car which was there ‘for ages’ getting the conversion done, the ‘wiring was a bit of a headache’.
          (Quotes from one of the company owners doing the conversion)
          I only know about the car as in the early 2000s I was running a Renault 25, Fuegos and S1 Espace at the time and had been getting some work done, probably on the 25.
          I will try to find out more as the two brothers that owned Reo have retired to a town near mine, only a few hours drive away.

    1. What the…? There’s a mashup I’ve never seen before. Someone got ketchup and barbecue sauce on my escargot!

    1. Not really, at least not without going the Toronado route or similar. The last RWD Peugeot built would have been either the 504 or 505 (depending on whether you’re talking European or rest-of-world production), and there is no chance of any of the FWD engines bolting up to the gearboxes in those cars. Might be able to do some sort of intermediate shaft arrangement or something, but you’re really just better off trying to squeeze as much power as you can out of a PRV engine in those cases.
      One corner case that I can think of: drop the 3.0 V6 into either a Peugeot 405 Mi16x4 or Citroën BX 1.9 GTi 4×4, remove the front driveshafts, spool the front end, and either figure out how to have the 3.0 drive the hydropneumatics in those cars or remove them entirely… But that’s a lot of work to end up with a RWD 405 or BX.
      What might be interesting would be to import a Peugeot ROA (pictured below) from Iran and start with that as the basis for a swap – given its Rootes origins, it may be possible to get a 289cid Ford V8 in there with some work…

        1. Did the V6 ever come paired with an AWD drivetrain? No idea if the BX/405 gearbox and diff, etc. would hold up to being behind it.

          1. 405Mi16X4 Turbo had more torque than a V6. Diffs would be fine as their work is halved. Gearbox should be okay but it’s always the weak point in AWD as any Suba WRX / Mitsi Evo owner will tell you.

          2. I’ll admit that I’ve been trying to turn up info on a XU9J4 that came from the factory with a turbo and, outside of aftermarket conversions, am coming up empty-handed. Do you have any more info on this? There are a lot of very tempting reasons to want one of those…

    1. And let us not forget that other Citroën-powered star of the silver screen (in at least two sci-fi flicks of the time and varying degrees of dubiousness, anyway), the Trihawk.

  3. There is only one logical answer to this question, but it comes in multiple parts.
    1) Find a Peugeot 405 Mi16.
    2) Transplant the 3.0 V6 into the Mi16 (much as was illustrated below and here; details are in French).
    3) Transplant the leftover Mi16 motor into a 205 bodyshell (preferably one from a non-GTi so that it’s a complete sleeper).
    4) PROFIT!

          1. Agreed – but this is apparently a case where ‘too much’ needs to be between the axles (preferably behind the front seats) and not in the nose.
            That said, if someone feels like doing a 6-cylinder recreation of the 205 T16, I’ll heartily support and endorse their efforts!
