Steve Hiatt Posted December 21, 2012 Share Posted December 21, 2012 The 6BT is heavy but has a lot going for it. It's one of the most reliable engines ever produced and can be tweaked cheaply, including upping the revs. It's fitted to the Dodge Ram so lots of high performance bits from the States if you ever had the urge. For me though it's the noise at tick over that swings it, not quite at Gardner status but not much sounds better than a Dodge Ram at tick over.

ToyRoverlander Posted December 21, 2012 Share Posted December 21, 2012 Toyota 1HDT (4.2 6cylinder). If you don't like the standard 160ish horespower theres a guy in Aus that does custom turbo's for them and has done a few with 200hp at the wheels (35") ! All totally reliable. http://forum.ih8mud....m-35-tyres.html He's got his own 1HD-FTE (the electronic one) at 200kw at the wheels and more than 750nm... http://forum.ih8mud.com/diesel-tech-24-volts-systems/655068-gturbo-ct26-bad-boy-stage-1-1hd-fte-hdj79-over-200kw-wheels.html Buy an 80series and use that drivetrain...

ToyRoverlander Posted December 21, 2012 Share Posted December 21, 2012 I forgot to mention, that engine (As long as it hasnt got an 'E' in the type designation, like 1HD-FTE) is a one-wire diesel. So no complicated electronics. Quote Link to comment Share on other sites More sharing options...
nicks90 Posted December 21, 2012 Share Posted December 21, 2012 What about a Mercedes-Benz OM647 (as used in some Sprinter vans) ?? 2.7 litre straight-5 dual-overhead-cam turbodiesel ; pleasantly free-revving; outputs up to 170BHP and 400Nm of torque. Not too heavy either (some of the other suggested engines would make your vehicle so nose-heavy it'd be plagued with bowel-loosening levels of understeer). --Tanuki. thats pretty much the same engine they use in grand cherokee and merc ML series trucks. Pretty good engine, I was certainly very pleased with its performance in the cherokee. Easily upgraded with a plug in box to give it 200bhp and 460Nm torque and now I am full of cheesy grinning and 'boy racer lead right foot-itis'. Does alright on fuel too, steady 70mph returns 9.5l/100km The engine also runs with a completely standalone engine ecu in the grand cherokee, and the auto box (also merc) also has its own stand alone ecu, so wiring should be fairly simple with no BCM and other hellectrikery to worry about.

mickeyw Posted December 21, 2012 Share Posted December 21, 2012 I saw a thread with a chap putting a Cummins 6BT into a Defender 90 on LandyZone. Link here. Failing that, a big Jap diesel lump wouldn't be a bad shout. I've got a Mazda SL35Ti waiting in the wings for a long term project of mine, but I don't think that meets your power requirements. Toyota do a 6-cylinder diesel I think? For simplicity the Mazda sounds a good option. It mat not be mega BHP, but Jon Holmes will vouch for its excellent towing grunt. Just remember you still have a stock Landy transmission, so too many torques will cost you elsewhere <grin> Quote Link to comment Share on other sites More sharing options...
cackshifter Posted December 21, 2012 Share Posted December 21, 2012 If you DO want a cummins, horseboxes might be a good source as they don't usually get much use before dropping to bits. This link http://www.ecologicalvehiclesolutions.com/VA_4BT_D90.html is a 4BT in a 90 (not such a tight fit), smaller Leyland/DAF trucks used them I think.

bluespanner Posted December 21, 2012 Author Share Posted December 21, 2012 Lots of food for thought here! Fetched the thing today, it came from Ben at York Land Rover Services on the A19. I'm very pleased with it, it has no rot whatsoever and is fitted with a new big yoke front prop and a set of brand new genuine springs and shocks from a puma. What I think ill do is fit my 200tdi from under the bench to get it mobile, then set about looking for a big lump Quote Link to comment Share on other sites More sharing options...

HPLP Posted December 23, 2012 Share Posted December 23, 2012 Is no-one considering the gmc 6.2 v8s any more? Ive always thought them ok with amazing torque. H Quote Link to comment Share on other sites More sharing options...
DaveSIIA Posted December 23, 2012 Share Posted December 23, 2012 Is no-one considering the gmc 6.2 v8s any more? Ive always thought them ok with amazing torque. H Very good torque, relatively low revving but not that friendly towards LR transmissions (not that many higher torque engines are though!).

NRS91 Posted January 14, 2013 Share Posted January 14, 2013 GMC V8Ds are paper weights... Cummins is a great engine... glad i did the swap into my 90 now!mine started life as a 130hp DAF 45 one. Now got a 160hp pump (with 3200rpm spring), +40hp fuel pin, +40hp Injectors and a HX35 Holset running 40-45psi if i get a bit frisky with the throttle.should be in the 200-300hp range and approx 500lb/ft of torque.Will pull a 5ton trailer in 1st high no mither but needs an overdrive to get the best economy at top end.a 1800rpm at 55mph i get 35mpg but if i push her above 2000rpm (65-75mph) it only does 20mpg (what i used to get out of the 200tdi) so a roamerdrive should drop the 70mph revs down to the magic 1800rpm theyre a heavy old lump and its some heascratching to get her in but as they say Prior Prep and Planning Prevents tiddle Poor Performance.Heres some vidyas for you to wet you appitite: Quote Link to comment Share on other sites More sharing options...
bluespanner Posted January 14, 2013 Author Share Posted January 14, 2013 Ahh small world, I added you on Facebook a while ago so I could see your land rover photos. Why did you go close coupled as opposed to remote transfer? And is there anything you would have done differently in hindsight? Quote Link to comment Share on other sites More sharing options...
NRS91 Posted January 14, 2013 Share Posted January 14, 2013 the LT230 is 5" further back as it is... the props 100mm shorter than standard and needs to be a wide joint version with a small tweak to the rear axle to improve the diff joint angle. Divorced LT230 simply wouldnt work!Transit Mounts are the next task to give it abit more rubber supportand theres have been a few tweaks ive done as ive gone along to make it better as you will have seen on my FBRakeway short rear output with x-eng brake for the lt230 to gain 70mm more room will be the next mod (if rakeway ever pick up the phone or answer emails)and Roamerdrive t drop my revs to 1800rpm at 70mph for 35mpg cruising in quiet will be essential i think.HX35 turbo and the injectors were a good mod and well recommended i know how i will do it next time (101 needs a big diesel i think ) but trying to recolect on all the little tweaks ive done over the year is hard lol Quote Link to comment Share on other sites More sharing options...
bluespanner Posted January 14, 2013 Author Share Posted January 14, 2013 Hmm. I don't think I'd have any prop issues in my 110, and think a short prop between the gearbox and transfer would be easier to do nicely than close coupling. Need a daf 45....

NRS91 Posted January 15, 2013 Share Posted January 15, 2013 close coupling is a pain but it solves a lot more issues...having them close coupled and the engine righ back would give nice weight distrubution and long props in a 110... so personally thats how id do it lol Quote Link to comment Share on other sites More sharing options...
Eightpot Posted January 16, 2013 Share Posted January 16, 2013 I had an Isuzu 2.8 sourced from a Frontera (more powerful than troopy version), and with a big intercooler and a couple of light tweeks it was awesome. I've had to change back to a 300Tdi now as I mullered the 4 speed box the Isuzu was mated to (nothing to do with the engine), and the difference in torque is huge. It's a comparable step down to changing from a TDi to n/a engine. The Isuzu is a very compact engine as well and fits nicely in a LR engine bay, more room to work around than with a TDi.

NickMc Posted January 17, 2013 Share Posted January 17, 2013 What do Rakeway charge for the remote input shaft? Quote Link to comment Share on other sites More sharing options...
NRS91 Posted January 17, 2013 Share Posted January 17, 2013 What do Rakeway charge for the remote input shaft? not sure but their LT230 Short Rear Output is £390 inc Vat and Ashcroft FTC5090 is £44 if that helps you sort of gauge where its at. Best bet is to ring Rakeway they dont reply to emails. Quote Link to comment Share on other sites More sharing options...
NickMc Posted January 17, 2013 Share Posted January 17, 2013 Have you made a shaft to suit with the FTC5090? I've got a gearbox out of a scrap DAF and i think i can probably do a deal on a 6BT with a mate i think i could be very tempted to put one in my 130 Flat bed Quote Link to comment Share on other sites More sharing options...

I've got a gearbox out of a scrap DAF and i think i can probably do a deal on a 6BT with a mate i think i could be very tempted to put one in my 130 Flat bed got my mates engineering company to turn down the prop yoke and press the FTC 5090 into it with 10t force and then weld them together and then turn it down to provide a smooth seal ready finish... though a custom shaft would be preferable tbh Quote Link to comment Share on other sites More sharing options...
Ash.Witty Posted January 18, 2013 Share Posted January 18, 2013 I am also doing the 6BT conversion after nick took me for a blast in his purple 90, I am using a different gearbox though and fitting it in a 110 will make it a little easier than squeezing into a 90. Can't wait for all the low down torque for off roading, and 250+ BHP on the road Quote Link to comment Share on other sites More sharing options...
ronnie_rotten Posted January 19, 2013 Share Posted January 19, 2013 what sort of fuel economy do you get from a lorry engined landy?!? i know.... who cares? but i'd still like to know... Quote Link to comment Share on other sites More sharing options...
NRS91 Posted January 19, 2013 Share Posted January 19, 2013 if i keep it below 2000rpm when im cruising about 35mpg... still pretty spirited driving thoughif i get above 2000rpm when cruising and im driving spiritedly about 20-22mpg... the same as my 200tdi disco engine used to manage.full throttle is scary so rarely used, half throttle is enough to move you along at a fair lick. full throttle makes an Audis decision to overtake quite futile lol Quote Link to comment Share on other sites More sharing options...
