modern turbo diesel engine power delivery whilst impressive is very sudden and short lived. This is fine for chubby tin tops BMW's,
Audi's etc for regular everyday driving. In fact I wouldn't go back to a petrol tin top now.
But IMHO it would be rubbish in a lightweight 7 style car. Too much torque too soon would equal wheelspin and turbo kick out of corners is asking for
grief.
What's wrong with tuning a V8 n/a petrol motor?

I have the BMW 2.5 diesel in my 525 estate. About 177bhp and 295lb/ft torque. Pulls like a train, even in such a big and heavy car. The 3.0 is the
same, but more so. However, these are NOT small engines ...
I have a 330D and it does pull like a train, but it also corners like one! The 3 litre BMW diesel is ~100kg heavier than the 2 litre and not much
quicker.
The extra displacement makes the delivery less peaky, sure, but the downside is that chuffing huge lump of metal you're trying to convince to
turn around corners.
I think most diesels are too heavy for a 7. A big-ish bike engine seems much more suited to the original 7 ethos. Light, compact, enough torque to
cruise on, mad power when you want it and an addictive noise to go with it. Oh God, i'm going BEC!

I reckon if you have a large 7 (book + or Viento) and ran it with turbo diesel and auto box, it might well be a laugh
Go for it

No real soot - or at least no worse than petrol exhaust - from a new design. But the problem with diesels (have one as a tintop - it's very
good for motorway schlepping of large amounts of stuff) is the noise at idle. I'm told it's the pump(s) that make most of the racket.

They have to do excess of 20,000psi, I think I'd make funny noises too

Hi Geof,
I agree with nick 100% on this one.
If it's economy that's the main reason for your thoughts, then have you considered converting your V8 to LPG?

Diesel In locost?
Thats Sacrilege, my expierence of diesels has been great ,but they are great for specific reasons,
It wont respond like a petrol, the car is light and the short power band and high torque wont suit the response you would expect in a small nippy
locost.
Sounds like a truck!!!
Even Alfas diesel sound like a diesel!!!
Lastly ,
Diesel engines for trucks, car engines for cars and (this'll cause a stir) bike engines for bikes

OK only 160Bhp to start with, but with turbo's will go to 250bhp plus, and 400 plus Ft Lbs. might need a different geaboxs and back axle
though!
Plus its a V8.
Hey, not fair! I was going to suggest a V8 turbo diesel! You've got the wrong engine entirely though!
What you want would be the Ford 6.0 Powerstroke. 320Hp in stock form, with chip and open exhaust it'll see ridiculous power in the 450 to 500 Hp
range.. racing versions with bigger turbo's, injectors, etc., etc are pushing 1,500 Hp. (silly money spent though, and not a snowball's
chance in hell you'd pass emissions)
But then again, the V8 engine + transmission combo weighs about the same as a heavy BEC or light CEC. They're about the same size, too.. And if
you think a normal Seven has bad aerodynamics, just wait until you've made space for the HUGE radiator and intercooler!
But hey, you asked for silly ideas, no?
Seriously though.. late model VW or AUDI turbodiesels? Shouldn't be too big, and offer very decent power. Just taking a quick look:
Let's see.. the 2006 and up Golf Sportline is available with a 2.0l 170Hp engine. Too bad its 6-speed transmission is useless for a Seven..
I'm guessing the 2.0 in the A4 is the same engine? The A4 also comes with 2.5, 2.7 and 3.0 versions though.. the 2.5 and larger are V6 engines
though, 167, 180 and 204hp respectively.

Hm.. perhaps the 1.4 TDi from the Smart ForFour? Only about 95Hp in stock form, but it should be relatively small and light, as it is only a 3 pot..
In the 1000kg Smart it accelerates to 60mph in just over 10 seconds. I guess acceleration wouldn't be half bad in a car that weighs about half..

The reason I suggested the auto, is so you avoid the need to change gear every second under acceleration.
Makes sense to me, though with injection and my silly new diff, I'm expecting 50+ mpg at constant throttle, which given todays traffic
conditions is what it'll be most of the time!

Thats made me think. May be a bit on the expensive side but jag deisels are seriously quiet.
How long can i resist the temptation to drop a V8 in?

what about merc diesels, they come in rwd with a gearbox the right way round..
also vw 1.9tdi's in passat/a4 and a6 are longitudonal so the sump should be ok, just need a gearbox/adapter..

Hmmm Now what type of fuel was this, and last years Le Mans 24 hours winning cars fuelled by?
1. The point of a journey is not to arrive.
2. Never take life seriously. Nobody gets out alive anyway.

the V6 would be a weighty option for 150Bhp
PD150 is a 4 cyl option with the same power out put it would be less weighty. this can be chipped to 180 to 190 bhp.
the PD130 can be chipped to about 170 bhp.
.
i would have to agree on the VAg (audi VW seat ENGINE)
Erm i have 3 vehicles with them in the passat FWD 2.5TD1 180BHP now 220BHP with 410Nm and the audi a4 1.9tdi quattro 130 Now 170BHp and 366NM, and the
caddy FWD 104bhp.
The engines can come longatundinal or regular depending on if its came from a quattro on a FWD, if i was you the 1.9tdi Quattro engine is the better
one, its smaller, lighter, sits the right direction, sump is tight up and adpaters for type 9 etc are available.
and for £1000 there is a 210bhp 445nm upgrade including new turbo, and superchip from starperformance!
Built, Ivaed, Drove and now Sold - 2011 MNR VORTX RT+ 2000cc Zetec on R1 Throttle boddies.
