Which diesel went in a D-series?? A CX I presume?
The D-series four is "bombproof" as you say, but one might want a
little more power. The Maser V6 in the SM is dogshit and I greatly
enjoyed seeing one sawn up for a cutaway display for a vo-tech school
some years back.
Can the CX engine be built "reverse rotation" or are there two
different block assemblies?
Many GM engines can "go either way" with cam and distributor gear
changes-SB and BB Chevy, Corvair-as can the Detroit Diesels. (Which
mostly weigh more than an entire DS.) I suppose a Chevy II four as
well, which would probably fit in a D. Many Hondas are wrong-way too.
Reverse rotation is why the Mazda rotary wasn't installed in the SM:
otherwise it would have been the common swap. In the US a SM wasn't
worth the price of an engine overhaul for a couple of decades at least.
Are any swaps common in Europe?
Bret Ludwig ( email@example.com) gurgled happily, sounding much like they
were saying :
The D lump uses a different block to the CX. I'm sure you could rebuild a D
block with CX25 liners/crank/whatever with a custom made cam, but why
bother? The CX25ie is "only" 10bhp more than the DS23ie. Helluva lot of
work for not much benefit. And that's before you've rigged all the L-Jet
injection in. Yes, the turbo's got another 30bhp, but even more hassle.
Better to start off with the D lump and use old-fashioned tuning.
Oh - and the CX 2200D/C35D is 66bhp.
But I do know of at least one D with an SM engine.
I s'pose you could follow the original design philosophy, and use an air-
cooled flat 6 as Citroen were originally intending. Now where on earth
could you get one of them?
Back in the 70's the boss of the Citroen garage which serviced my
Dad's GS Break used to drive an SM with a D-Series engine.
Given the fact that an extraordinary car deserves an extraordinary
engine, if I were a genius of a mechanic I would try to install one
of the following engines into a DS:
Toyota Prius (the complete hybrid powertrain)
Mazda RX Rotary engine
Subaru flat 4 engine /w turbocharger.
One might also try the 3.0 litre V6 out of a late Xantia.
Chances seem reasonable that all of these engines would fit under the

The Mazda rotary would be perfect but getting it to run backwards
would be impossible.
With most piston engines, direction of rotation is limited by the
accessories, particularly the oil pump. GM engines with distributor
driven pumps can be run reverse by changing the cam and distributor
gears. This includes the small and big block Chevy V8's, the Corvair ,
and probably the Chevy II four cylinder which is half a small block
Many Honda engines are reverse rotation, or so I am told.
Reworking the transaxle may or not be possible, to allow a standard
rotation engine to be fitted. This was done on VWs a lot-for mid engine
and Corvair swaps and to use Type II transaxles on Baja Bugs (Type IIs
used a reduction box at the wheel end), by flipping the ring gear.
