Diesel into a P6

Other problem I can see is insurance, you'll need a trade policy that covers anything, or you'll be talking to Adrian Flux etc and paying through the nose for a Modified Vehicle, been there....
 
The engine is from a 205 peugeot

The gearbox is original P6 via adapter. :roll:

It needs another gear for going over 60mph on motorways. :(

The present owner finished off a duff installation.....


Insurance will be a nightmare!
...but I got a Trade Policy!!!!!!!! :D :p :D

PS - Rick you're supposed to be unwell!!!!! :wink:
 
I'd have thought the engine from a 205 would be a bit weedy for a P6. I'd be looking to fit something from a similar sized car.

Same engine was fitted to early Pug 405 diesels..

...the problem is the use of the original P6 gearbox.
 
Unless I'm mistaken, that engine seems to have a Lucas RotoDiesel pump, which I'm told is NOT at all happy with anything other than diesel.

Had it got a Bosch pump like our old 305 had, it would likely have been OK with Veg Oil.

Apart from insurance, is the car still legally tax free? It's obviously not the same as when it was built, so maybe that needs to be verified?
 
Yes it will be tax exempt, the basic rule is that all regulations apply to the oldest part of the car, so you can fit a modern engine but only have to pass the emissions test relevent to the cars age etc..

Quite correct - The Lucas Rotadiesel is a terrible pump even on proper fuel.
However it is fairly simple to replace the pump, lines and injectors with a Bosch set-up
from a later 1.9 turbo diesel from either a 405 or 306 engine.
 
i have known that car for a number of years i have seen it driving around,its only 10 mins away from me,the body work isnt the best but it is used everyday,will try and scout a look bri

That would be handy Bri as a 160 mile round trip for me.

Interested in the usual suspect areas if you do go look...

hi all,been to look at this today,it needs work,nearside d post wants a bit of welding where the rubber seal goes,had back seats out offside doesnt look bad while nearside wants a bit weld,all chrome not the best and interior isnt correct,offside hockey stick wants a little patch but the rest of the car looks solid,the original interior looks as if it might of been mango with the door cards glove boxes furflex etc,it has black cloth boxpleat seats,the orignal colour of the car is mexico brown but has been painted badly and looks a bit like tobacco leaf,now to the engine,it is running the original p6 gearbox,it has wat looks like a leaky number 3 injector but this car drives beatiful,its really quite quick up to 70 but really needs another gear,which is a shame cos it changes gear lovely,if i had the room i mite have give this a go,but i havent,i would say its worth saving hope this helps Bri
 
Cheers Bri for the info and going to see it.

You reckon the MoT would be quite easy or more a weldathon round the rear end?

Suppose I could fit an SD1 5 speed to it?
It has been done before.

Pete
 
Hi Pete,i dont think it would take much to re mot this car,but dnt count me on it,it is by all means no minter and would take alot of time and money to make it a real stonker,but none the less its a p6 and it is definately without a doubt worth saving cheers Bri
 
Personally I think all the engines mentioned so far are terrible ideas. I suggest the following instead:

Jaguar 2.7-litre twin-turbo V6 sourced from an S-type - manual gearbox as standard, most people ticked the auto option. I think it's the same ZF 'box either way as is used by BMW. Should fit. Very smooth engine. The newer 3-litre version launched this year is auto-only, but I assume that as, again, it uses the same ZF box as BMW, a manual will fit.

BMW four-pot - ideally the newer all-aluminium engines. The current BMW 123d is a 2-litre 4-pot with twin turbos, 201bhp, 300 lbs ft. The single-turbo as in the 1/3/520d is now 175bhp, 260ft lbs. It's still a four-banger diesel, but it's as refined as they get.

Volvo inline 5 - not the most economical or refined, but very good nonetheless if it'll fit.

Mercedes-Benz' inline fours and V6s are very good, too - auto-only for the V6s (7-speed suffering from terminal indecision), the four-cylinders have a manual or a sluggish five-speed auto.

Forget Ford, French or Volkswagen diesels - except for the Peugeot/Citroen V6 (which is the Jaguar engine mounted sideways).
 
I wouldn't know where to start to get a modern common rail tdi engine swapped into an old car. If that weren't a problem though, how about the tdv8 from the latest Range Rover? Very powerful, and it's supposed to make a good noise too.

That's a big, bulky engine, and not the best diesel V8 there is - the best is BMW's now sadly discontinued one in 4.4-litre form (the only all-aluminium diesel V8 ever to be put in a production car). Audi's 4.2 is apparently very good, too, as is the Mercedes-Benz 4.2 - sure, use the TDV8 if you want, but don't be surprised if it doesn't fit. Maybe in a P5 or an SD1, though.

Oh, and why would it be a problem to get a modern diesel engine into an old car? If you wanted, you could use the donor's engine, gearbox, diff, wiring loom, ECU, everything...
 
I gather there's a problem with modern V engines in the P6. They tend all to have twin cam etc heads and so are noticeably wider than the simple old Buick. Wouldn't stop me sizing it up though! I don't see any insuperable difficulty with any of the techy bits, although I'd prefer to start with a complete car to remove all the "new" bits from. There are likely to be two awkward issues, arranging the engine mountings and fuel tank and pipework. The engine mountings are crucial in getting a modern diesel to run smoothly and are typically much higer on the car than the Rover V8. This is awkward on a P6 because of the intended weakness of the inner wings - all the strength being in the bulkhead. The fuel tank and pipework I have the impression is considerably more complex than the Rover, perhaps with a degree of pressure in the tank - not insuperable but would need to get my head round the problem.

Cut off the front end and build a space frame- That could start a new debate - what front suspension system would you fit ?
