Diesel Power!
Lawnmower - 20/1/05 at 11:03 PM

(oops, will have to retype this)

anyone know of any decent and preferably cheaper diesel donor engines?

Diesels have a shed load more torque for equivalent powere ouput than petrols, and they are less likely to blow up, always a bonus in an accident!

bmw like in the latest series 3 is supposed to be good- a bit pricey i expect

the vauxhall 1.7 dti not sporty, but probably fairly cheap now.
(~77bhp at 4.5k revs but your in the red at 5k , 135lb/ft toque, 0-60 ~17secs, reliable )

but can it be tweeked a LOT?

Advice, discussion and ridicule welcomed

I think SSC built a diesel Stylus...may be worth giving them a shout


stephen_gusterson - 20/1/05 at 11:13 PM

the bmw 3 series diesel is a fantastic engine

150hp and more torque than a 330i.

but as you say, would cost a bomb unless you can wait 15 years

what about the latest golf diesel, they have been round 3 or 4 years now and push out 150bhp....

Or the vauxhall 2 litre. I think that was 120ish bhp. Biggest problems would be weight and where to put the intercooler & turbo etc....

Westfield did do 1 car, called it the weisel i think.

The Ford Focus TDCi engine (1.8 litre) comes in 3 guises. The top one being 115bhp. Loadsa torque (250Nm ish). The focus' with those in are quicker 30-60mph than the ST170... Its a good engine...may be a tad expensive though!

You don't need torque unless you are pulling the weight of a diesel engine round. They usually weigh as much as a small village. Unless you're building a locost delivery vehicle please abandon this train of thought. Nobody does tuning gear at locost prices for diesel engines and they aren't cheap to buy if they are worth having.


MikeR - 21/1/05 at 12:09 AM

hold on tho........

loads of torque so slap a really low ratio diff on it and watch it fly..........

lets not hold someone back if they want to do it

And then there's the exhaust, right next to your head, and some incredibly poisonous fumes.

Then there's the tractor impersonations!

Westfield advertised a diesel '7' in the recent past (about 8 years ago) don't think it caugt on (I recall somebody claiming to have the demonstrator)
I've got a turbo diesel ordinary car & sure it makes the power but the power band is only about 8rpm wide, & from clarkson's comments the new ones are just the same.
My V8 makes within 10% of peak torque from 1500 to 4000 revs - I expect my pug diesel makes within 10% of peak torque from 2400 to 2700revs.
It goes OK & the economy is brilliant. But it's nowhere near as nice to drive.
Cheers

Is this diesel for a Landie, or for a LoCost?

If for the Landie go with a Isuzu 2.8 tdi. I have used 3 of them in conversion and can't say enough good things about them...


David.


flak monkey - 21/1/05 at 12:25 AM

One problem if you used a diesel engine would be getting the torque down onto the road without losing traction. Most people will tell you a Locost will spin its wheels in 3rd...with a petrol engine. Our 1.4 tonne focus with that TDCi engine will wheel spin in 2nd...easily (with traction control, which i notice they have stopped putting as standard on the new ones...thats just silly)

I drive the 115 focus TDCi, I knew it was quick (for a diesel) - but quicker than a st170 30-60 is cool. looks like i will have to go and find a st170 to "play" with!

...i wonder what it would be like if it was chiped, 30% more torque and 30% more horses.....


brunocrossley - 21/1/05 at 11:06 AM

How about a Montego Turbo Diesel? Complete donor cars really cheap and RWD adaptor kits easily available.
Most diesels only rev to 4K5 ish. Just pull a higher diff ratio.
You could try a tweaked TD5 - 230BHP and they howl with the cat removed. Try 'Twisted Animation'

There was a chap who used a Citroen Diesel 1.9 turbo. He said it had shed loads of torque and was very quick. I think the gearbox was from an LDV van or something....all nice, cheap and available!!


flak monkey - 21/1/05 at 11:28 AM

Another diesel car fact...the Golf GTi diesel is faster than a petrol GTi... not 0-60, but mid range (30-60) its quite a bit quicker...


Lawnmower - 21/1/05 at 06:50 PM

This Golf?
http://carsearch.yahoo.co.uk/pdb/product.jsp?catId=100354123&pid=12258796

i know its not one of the newer PD engines, but these might be a bit more available?

also won't fatter tyres help?

I wouldn't touch a VW diesel engine. Cracked heads from new and not too hot on gaskets either.

Diesels also tend to be a lot deeper than petrol engines too, as the bottom ends need to be stronger.


Lawnmower - 21/1/05 at 11:26 PM

If i had the money spare then I would consider this

only if its the top model golf - lower cost ones are a wanky 75hp!!!!


something like 48% of new cars are now diesel. I think that the negative people that express bad things about diesels will soon be in the minority opinion. when you are in the car you cant hear the engine - you just benefit from heaps of toque, a nice powerful lazy motor and masses of mpg.

That's a little controversial isn't it?
Apparently petrol engines push out more toxic fumes, just that you can't see them. I'm impartial either way - but I prefer a smooth petrol engine than an oil burner anyday.

Granted, the diesel has more torque - but for a locost...? I think you would loose a lot of the essence of what it stands for.

Personally I'd stand well clear of diesel engines, but each to their own. If that's what floats your boat then go for it!

But modern powerfull turbo diesles are far from "lazy" if you want a bit of performance. They have a stupidly narrow power band which means you have to really stir the box to get the best out of it. I always found them slightly dissapointing to drive, the turbo gets going and you start to get a nice push in the back and suddenly it's all over and time for the next gear.

Granted, on the motorway where you don't change speed too much they are a lot better.

I hear what your saying, and to a certain extent i agree.
I drive a 2002 Vauxall astra 1.7dti estate
which has a rediculaous lag between flooring the pedal and the turbo kicking in, just as like you say you change gear.
Gives a very slow start from getting on a roundabout and when overtaking

My colleagues however have both got VW golf and a Passats estate, which both have the 130bhp engine. Have not driven them, but they say its just like having instant power, and the golf will beat boyracers everytime

Imagine that engine in a car the 3rd of the weight!

On the plus side my car lease runs out in march

btw will fat tyres on the drive wheels help make use of that torque? or am i getting confused?

The Volvo V70 D5 engine is great. 165bhp standard and a £300 chip away from 185bhp. Also more torque than you could ever use at once.

It is quicker than the Scooby 50-70!!

Will tow 2ts aswell.

Adam


flak monkey - 22/1/05 at 10:08 PM

Theres no turbo lag on our Focus... its just instant power. You certainly dont have to wait for the turbo to kick in.


MikeR - 23/1/05 at 10:52 AM

I've driven the volvo and been impressed. 5 up on the motorway doing 80mph (not in this country obviously officer) and we returned just over 40mpg.

Around town........ well first gear is a bit useless as you are only in it for a couple of seconds but it certainly shifts and overtaking is ........ quick
