Alternative engines

[Heggs]

I have a TD5 defender and have been tinkering with the concept of dropping in a V8 diesel, I have spoken to Brunswick Diesels and been advised that they are not doing these. Has anybody had any experience with conversions like this. i am aware also that Cummins are building a new v6 and a v8 for the dodge.

Any info advice would be appreciated

I have a mate who ripped his Td5 out of his Defender and put a crate Isuzu 4BDIT in , she pulls harder than a school boy !!

Cost $13 grand for the mototr and kit and 6 weeks of Saturdays to get it sweet

urm why?

aside from installing a v8 diesel into a car sized engine bay (and the deefers is about the most spacious I've seen in a long time) means you will toast the back end of the engine.

this invariably accelerates the fatiguing of the metal in the block which results in the loss of tension in the head which means blown head gasket and if not caught quickly enough means a takenout engine.

back of the napkin maths shows that if you double the pressure of air in an engine you can make about 2 twice the power of the same sized engine OR the same amount of power as an engine thats double the capacity (of course how the power becomes available is a totally different story with the bigger engine delivering in a "lazier" slower fashion.

give it a bigger intercooler, a bigger exhaust, chip it and you're laughing more power with the same effeciency if you choose to take it easy on the noisey pedal.

(I'm also looking into a VNT turbo for big red with some other rice boy playing at the 200K Km mark)

Suprises me Brunswick Diesel are not prepared to do it as they have done them in the past, though I believe that they did have problems with them overheating and may be why they are not doing them anymore. I know personally of 3 done.
I reckon the way to go would be the new small block Cummins V8 with a 6spd Allison auto tranny. Would take a bit of work and I would not expect any change out of $20k.
From memory an AULRO member is takling this at present.
Most people that I know that have had the big Chev V8 diesel conversions into Toyotas, Nissans etc have not been happy with the finished item power below expectations and heavy on fuel.

Hi,, I looked at purchasing a defa 130 with the v8 diesel conversion already done. The guy had spent a fortune on trying to keep it cool. Big oil coolers, thermo fans, altering the water jackets in the heads etc etc. It sounded great but in my opinion NOT worth the trouble. TD5 much nicer to drive ( chipped, exhaust yeah ha.)

There is a chev powered defender in Kal and it is an overrated POS.It takes off slower than my D/gas Tdi and I'm a mile down the road before he catches back up.It turns like crap,he has cracked the spring towers and it is so tight in the bay you cannot work on it,and it uses alot of fuel for not much gain.There is alot of better idea's out there,I'd work the Td5 and fit a higher high range gear or swap the transfer to a disco one. Pat

[Heggs]

I guess from the sound of it no one has really had much luck with the v8's, i might have a bit more of a look a round then, I have time and dont wont to do something i will regret latter. the td5 I have now is a very good motor very fuel efficient and after 200k it has given great run, I will prob hold off for a while and do more resarch into others.

Brunswick said that they have done defenders in the past but had to many issues so will not be doing anymore,:(

[PAT303]

The price quoted by Brunswick was around $22K drive away,thats a stupid amount for a donkey engine,the yanks don't even repair them,I found scrap bins full of them on an American auction site that sold for nix. Pat

[D110V8D]

Dont put a V8 diesel in a Defender! I have been there and it's not a good idea. Cooling issues are the main problem, mainly due to lack of space in the Defender engine bay.;)

[lambrover]

I have also heard of the Duramax engine being fitted. but as also mentioned I would be fitting the 4bd1t isuzu engine old school reliadility and heaps of torque and good fuel econemy, but you have a good TD5 so work with it do your home work and how much power do you realy need.

Thats the one I was thinking of.

[extreme6.5]

Coming in a few mnths late on this thread but I have had a 6.5 chev diesel in my 2001 extreme for about 4 years.It took Brunswick diesels 3 years to get the overheating sorted and it was my landy that scared them off doing any more.
They sorted it and it's now perfect, but it went back to their workshop probably 20 times....cost them enormous time and no small amount of $.
I just got back from a trip to Exmouth towing a 30ft (all up 5 tonne) boat/trailer.The last day on the way into Exmouth it was about 40degrees, we were driving directly into a 30knot breeze(my thongs blew away when I was about to get out of the car and threw them on the ground!).and the last 100k's or so into town is full of hills.
Not many vehicles would tow that load, under those conditions, and not overheat.
The temp got to 100 and held firm...it's sorted...
Some will say 100 is too high but the trick with cooling is not so much the number but to get the temp to hold and stop rising, this means the cooling system is coping with what is being thrown it's way.
Heavy/continuous beach work is no problem, was a huge issue, now no problem at all.
I couldn't overheat my landy if I tried to, she hangs between 85/92 under all conditions other than the Exmouth experience above.
The extreme/chev combo is awesome.
I lived with the td5 for a couple of years pre 6.5 so I can make a reasonable comparison.
On road-not a huge difference
On road towing-Chev wins by significant margin
Off road-a world apart, the chev is in a different league with all the low down torque...way way way better,
you need to drive/experience it to fully appreciate the huge difference.
Brunswick are still waiting to hear me say "it's totally sorted fellas" and I'll be in touch with then soon.
I doubt they will do any more though....:D

I think you have just answered your question! And nobody seems to have a different answer.

What about dropping one of these in the engine bay?

Cosworth - (http://www.cosworth.com/Default.aspx?id=1093918)

Not sure why LR hasn't thought of it given Ford and Cosworth have had a long association? :twisted:

[QUOTE=extreme6.5;[/QUOTE]

Thanks for the info, so we can all blame you for turning Brunswick Diesels away from Defenders :p, the money I was going to use to convert my 110 I have spent now on a Harley, I dont think the wifey would appreciate it if i went out and spend a few dollars more:( When the bike finally turns up that will be my every day vehicle an I will leave the 110 for the weekends and trips away

Perhaps because it has a race car power band, 4500-7700 rpm and would no doubt have a short and merry life in LR type service being bounced around in the heat and dust.

[TwoUp]

I have not helped the Brunswick cause either. We had some issues.

[Heggs]

I often see a white 130 around the Midvale/Bellview area in Perth, I'm not sure what he has in his but it sounds awsome when he cruises past. My TD5 will have to do now, they are a very good motor I have had no problems with it (touch wood:D) its has nearly 250k on it now and the mechanics at last service reckon i should see that again with out major problems

How did you do with the legalities - in particular the pollution controls?

Edit:
The following quotes are from posts by Scouse. IMHO Scott would have a far better knowledge in respect to this than probably anyone on this forum.


... these engines have been extremely good from what I've seen.

That's great news.
I haven't heard of this happening with the TDV8 before so let's hope it's a one off as they're a great engine. I recently had the chance to drive the new 10MY range, with the new 3.0TDV6 & 5.0 supercharged engines, & the TDV8 was still the pick of the bunch IMO.

I don't mean LR's TDV8,I"m talking about Tojo's boat anchor. Pat

No problem, Brunswick take care of all the paperwork and licensing.:)

I had assumed as much. The Toyota engine is 4.5 litres, the LR engine is only 3.6 litres.

Must be a co-incidence. Mopar don't p**s about with small engines like that. You can get a Hemi at 550 cubes with a 4.25" crank and a 4.5" block and a light overbore.

Nothing quite like the sound of a big Hemi. At idle it is a series of explosions and at 6000+ under load through dual twin 3.5" exhaust outlets is quite simply some thing you must hear at least once in your life.
