Any thoughts of using a diesel engine in a 7? If you were forced to use one what would you have?


graememk - 22/7/09 at 11:05 PM

no dont do it

but vauxall make a very nice 90bhp 1.3cc
and a 1.9 150 bhp both respond very well to re-mapping

gear box ? 1.9 sould fit something alfa / fiat


blakep82 - 22/7/09 at 11:24 PM

always wondered if the vauxall diesels from 1998 for example would have the same block as the xe or xev? although i guess the gearing in a type 9 box wouldn't be perfect


Ninehigh - 22/7/09 at 11:32 PM

Ah here's the thing, why not?

Bags of torque, hardy engine and like you say modern ones of the size most people are talking about give 150bhp stock. Imagine what you could get with a remap, a few tweaks and a big-arse turbo (maybe a twin one too )

All with the advantage of 50+mpg when you take it easy and still over 20 at full power

I got the 2l tdci in my mondeo and it's good for nearly 130mph, how would that feel in a seven?

Westfield made a factory supplied 90 bhp1.6 ford turbo diesel back in mid 80's,it did 0 to 60 in 6.5 seconds,I remember it because I had just bought a new XR2 at the time,and that could only manage 60 mph in 8.5 seconds.
Ive been thinking about it for my next build,along with just about every other engine out there,but have come to the conclusion that the best diesel engine would be the bmw 320d 2006/2007 onwards,coupled to its 6 speed box,and its own 2.56 ratio diff,standard this engine puts out 177bhp,you can chip them up to 250bhp, giving over 300ftlbs of torque,the 06/07 engine is all alloy block and head the only problem is cost,anything with BMW on it,even 2nd hand is expensive,and then there's whats it going to drive like,big wollop of power for 2000 rpm in each gear,and bags of torque,could make for interesting drive.

Heres a link to a guy who remove his bike engine to fit a 1.8 ford TD and thinks its better

Must say though,looks a tidy install Rescued attachment westy diesel.jpg

My thoughts exactly:

quote:
That westfield page says
It's a Ford Escort 1800 Engine with a turbo which gives it a bit more go it put out a round 120 bhp mark which for power to weight is just right.
Car weight is around 620 kg so works well. l had bike engine in it but this is so much fun and I'm getting round 65 mpg and that's with giveing it some all the time. It just comes back for more and it's all round fun.


DRC INDY 7 - 23/7/09 at 12:06 AM

I currently thinking about ford focus/peugeot 1.6 tdci 16v 110bhp in standard trim 300ftlbs with overboost standard so with a tweek should be rapid 50 mpg in my focus and thats giving it some push


blakep82 - 23/7/09 at 12:51 AM

in a few years i would strongly consider putting a diesel in my car. too late to change plans now, but when i want a new engine, turbo diesel looks fun


Ninehigh - 23/7/09 at 12:58 AM

See I'm at the stage where I'm in the market for a welder, so maybe an engine similar to the one in my current car, got the manual for it already


l0rd - 23/7/09 at 05:13 AM

What about the Nissan Navara engines.

I think they are 300Nm std not 300lbft

The VAG 1.9 PD diesel is available as std up to 150bhp and very easily remapped to about 190bhp and 320lbft.

The only issue to get over is the gearing, you need a really short first so bang goes your 0-60 time. However once its rolling you are on a winner if you can put the power down.

You also have the issue that it just doesnt sound as good as a petrol...

hughpinder - 23/7/09 at 07:16 AM

I suspect the major problem will be stopping wheelspin with all the torque, and so little weight...


britishtrident - 23/7/09 at 07:44 AM

Rover lump L series as used in the Rover 95 as standard easy to get 125.

The BMW diesel as used in the 75 and Freelander can produce a lot more power but it is also a lot heavier


wilkingj - 23/7/09 at 08:04 AM

No one has mentioned the required 3.14 or 3.38 Diff. These will be almost mandatory if you are using a diesel engine.

Volvo D5 ?? remapped will make 200+bhp and about 400 ft lb torque, and they will do 55mpg
(even in the volvo body!)
And I believe they are an all ally engine.

Lots of options, but crappy sound track.
Still you could run a big Hi-Fi and run a MP3 player connected to the throttle to get the sound track sorted

Then there is the Audi or the BMW as mentioned above.
All things are possible. It just depends on what you want.

IMHO:
I do less than 2000 miles a year and a petrol V8 is still worth it.
If I was doing 10k a year it would be a completely different matter.



James - 23/7/09 at 09:23 AM

That recent article in PPC was about a guy fitting a diesel engine in a Westfield. I can't remember the engine of course, but think it was probably a VW.

Cheers,
James


Volvorsport - 23/7/09 at 09:38 AM

ford diesel to type 9 box IIRC for the PPC car .

find a RWD M(0 for the whiteblock , in slots the D5 , now , if you think its a crappy soundtrack , you should have a go in one .

the BIG problem is removing the ECU to run the thing unless you can get an aftermarket one to work , see most modern ones have a trap and need some sort of software to prevent damaging it - otherwise its easily £1k to replace .

the vw LT 2.4 intercooled six can make some big power , and in volvo form comes with a rwd box , but its not popular


Guinness - 23/7/09 at 11:03 AM

As said, I thought the big stumbling block on using a modern diesel was the lack of aftermarket / standalone ECU's and / or the complexity of trying to get the OEM one to work when removed from it's natural home in the rep mobile.

I'd imagine there would be a big market for a Megasquirt equivalent for oil burners.

Mega glow anyone?

Mike


blakep82 - 23/7/09 at 11:13 AM

how do diesels work? i thought glow plugs were only used to warm the engine up, and they ran on their own after that?
what would the ecu do?

In simple terms they control the amount of fuel injected.

Diesels run at wide open throttle all the time. The accelerator pedal just controls the amount of fuel put in. Think of it like a foot operated tap!

On modern diesels they control all sorts of stuff, exhaust gas recirc, over boost, smoke control etc etc.

fueling is complex on a diesel i think.

where is dinosaur juice when you need him


Volvorsport - 23/7/09 at 11:32 AM

yeah , the common rail engines with electronic injectors are hard to swap over , more basic ones with mechanical fuel pump are a lot easier .

in PPC theres a company that offers a diesel standalone , dont how much it is tho .


dinosaurjuice - 23/7/09 at 01:06 PM

turbo diesel are great fun in kit cars

i use a 2.0tdci (actually a new generation peugeot hdi) running 136 hp. the 136hp isnt massive. neither is the 4000rpm peak power. but the fun you can have with 320nm at a measly 2000rpm is AWESOME

my first choice was the 1.6 TDCi. but i couldnt find a working donor car for the right money...

there are currently no (or very limited) aftermarket ECU's available for common rail diesels. its a case of finding a car which will allow the ECU to work without stropping to much when it cant find the ABS pump etc.

the VW 1.9tdi is an easy install - these have very simple ecus.

will


whitestu - 23/7/09 at 01:48 PM

No!! this is all wrong - diesel engines are horrible things.
Bike engines are perfect for these cars, or a nice free revving petrol engine, but not a diesel.

What about that 2.57 (ish) one BMW has? I forget which way round the numbers are, which way it goes for better acceleration.

And yeah I do over 10k a year


mad-butcher - 23/7/09 at 06:12 PM

After watching the VW racing on motors tv I think I'd fit one out of a caddy, theres a guy who races a diesel caddy van and boy does that shift.

+1

Please guys, don't go there! Its bad enough that le mans has been doctored to get the diseasels onto the podium, don't let them get into proper sports cars ffs...

yeah that caddy's awesome if i remember rightly, a fair bit of that engine is stock (?)


ss1turbo - 24/7/09 at 07:03 PM

2.2 DTi Vauxhall Omega? Think that was X20XEV based...and comes in RWD! No idea how tuneable it is though...and Vauxhall ECUs of that era really like to talk to the ABS unit...

Aftermarket Diesel ECUs are not going to be cheap, as common-rail piezo injector ones might actually fire 3 or more times per injection cycle to make them run smoother (quieter) - or even at all!


Ninehigh - 25/7/09 at 04:13 PM

I'm sure I've seen diesel chipping around, might not be massively different and give me loads more power but it'd be a start.

I'm thinking V6, around the 2.5l mark, should be good for around 300bhp somehow


jpindy3 - 25/7/09 at 09:16 PM

yeh put one in and chip it loads of torque,
but could you handle the noise plus it will be alot louder than a tin top.


dinosaurjuice - 25/7/09 at 09:57 PM

my rocket is completely un-silenced and isnt noisy at all. it does inject fuel upto 6 times per cycle... at over 20,000psi

vaux dti engines are CRAP. noisy, clattery, unresponsive and generally feel agriculutural.

i dunno about diff ratios. in 6th gear i do 36mph per 1000rpm. bonus of using standard FWD gearbox.


Volvorsport - 25/7/09 at 11:14 PM

apparently the BMW diesel racers use this ecu .
