Hello there.
Can anyone help me with the following please?
What is the highest performance lightest weight diesel engine which is readily available out there?
This engine can be straight 4 or 6 or a V6 or V8.
Further, it has to be able to be put in front of a gearbox for driving rear wheels.
If anyone knows anything about this could you please include weight and power figures please?
Or, any help would be appreciated.
Thank you.

The obvious choice is a VW PD engine.
I know a guy who has run 12.2 at about 113mph with one ( on slicks )
Not exactly daily driver material, but it was a 130PD, untouched internally.
Big turbo, nitrous, injectors, VAGCOM etc etc..
From what I recall, it made something crazy like 5-600lbft of torque !!!

To the last 4 posters.
Thank you...................intelligent informative information which I do appreciate and is a great help to me..
I would like to discuss this more with you please.
If you have time could you please put forward your engine choice along with why, and the power and Rpm range of the engine.
OK. So what is it going in?
Well. I do not want to say right now. But, it has moved on from a paper exercise and I am now at the serious side of the thought process.
I do not want to say what it is yet, because of all the negative PH "crap" which will then come flying my way.
PH, I am sorry to say, has a large enough body of "pub-talk geniuses" to be very annoying.
Instead of them actually doing something they prefer to come here and bang on about why they know best about everything.
Even to the point of them never having built such a vehicle, but they are still a "expert" on everyone else's business.
I can tell you that the vehicle is a sports car and runs a diff ratio of 3.08:1 or 3.2:1 and 16" diameter wheels with 245/50 tyres.
A top speed of 140 Mph would be fine. So working backwards from this point it would be nice to achieve sports car performance from rest up to the 140Mph mark. As of now the choice of gearbox is open, but I happen to favour the TKO 600 gearbox. My reasons for this are unimportant. Machining one off and fabrication of any parts it no problem.
Again any ideas etc would be very interesting and helpful at this stage.
Should I go ahead with this project I will give a detailed build of the project as I did with my own Speed Eight Tuscan build.
Thank you for your time and input.

With a TKO box your fine upto about 5-6000rpm after then shifting is like hitting a brick wall but with a diesel motor shouldn't matter you'll be getting all your power @ 4000 ish, but syncro's are not the best.
You have to give us a car size i.e golf, focus, or 4x4?
those duramax engines will run a 1000 squared but are quite big.
are you sure you cant tell us what your planning to build???

I would assume the smaller range of engines would perhaps rev better than the big V8's ??
I know the old BMW 2.5 td's rev, I owned one for a while. I would say that the car was an unreliable POS though. The engine may have made a little power....fortunately I sold it, before that failed too.
But if its a light enough chassis, then does it need the huge torque etc of a big cc engine ?
The smaller PD engines can make power ( or some of the 5 cylinder VAG/Volvo variants ), being smaller, will make less toruqe, yes. But that isnt always a bad thing as far as traction is concerned.

Hello all.
OK the project car is about 1200Kg and rear wheel drive sports.
The existing engine weight is about 210Kg.
An all alloy V8 sounds very nice.
But I will look at all of your suggestions.
This could become, well for me anyway, a very interesting and challenging project.
As of now I know very little about diesel engines.
You have already given me a lot to think about and go and check out.
Thank you all for that.

If you could take a trip to Malta....when I was there, they had a few mental diesel drag cars !!!!
This is just one of them !!!!

Ford Blurb says the AJD engine weighs in at about 202kg's but they don't say if that is for the V6 or the V8, nor if that includes ancilliaries. OK the project car is about 1200Kg and rear wheel drive sports.

The AJD has the SG Iron block which is supposed to be lighter than an equivalent ally block. Is this true? If it is I would imagine such a block has potential to produce lots of power.
Regarding your question on high revs. Seems that nothing really goes above 4500 RPM as the torque curve just drops right off, this is why lots of power equates to immense torque.
By the way I am not suggesting you use the Ford motor as I have no direct experience of the others. I expect though, that even a standard 2.7 would get a 1200kg car to 60 in 5 seconds. I figure that based on its ability to drag a 2600kg RR Sport to 60 in 11sec, that with the single turbo that suffers a lot more lag than the twin turbo Jag installation.
Interesting project, keep us informed.
