Custom Gauges × 4BT Cummins Discovery #48 [Land Rover Build]

Building a custom gauge cluster to hold all my new gauges in the original Land Rover dashboard surround. Here are the gauges used: www.vdo-gauges.com/instrument...

~ PART#48 in a project dubbed "Nanuuq" to swap out my lifted Land Rover Discovery 2's blown 4.0L V8 & boring ZF auto for a Cummins 4BT 3.9L turbo (Holset Super HX30W) diesel 4-cylinder engine (Bosch P7100 pump) with an NV4500 5-speed manual transmission. The AWD 4x4 will remain with the LT230 transfer case divorced behind it all, & plenty of Dodge 6BT parts too. Another big phase of my custom DIY build to create a do-just-about-anything off-road / overland rig. Did I mention it's a camper too?

[@Tinker1837]

Almost looks like a road worthy vehicle now! But my tachometer wiring still needs tweaking, since I'm trying to steal an output signal from the old Rover alternator for my RPM reading. (I have a laser RPM detector now, just to be sure the reading is accurate once it's working) Next up is a road test to verify the speedometer, boost gauge, temp gauge, and exhaust gas temps... which if all good means I can turn up the boost and start tuning it!

[@jamescunliffe9872]

As an experiment I think it's worth trying a longer exhaust to spin the turbo faster,as I see it the exhaust gas is exiting without producing enough flow to build a rise? Counter intuitive but you may also gain from having the end section actually having a slight narrowing taper!

[@jamescunliffe9872]

Engine tan coloured whole vehicle:)

Hey thanks man! I have no shortage of people to share it with when it's more complete that have helped & motivated me thru the project.

[@ggj666]

Very nice, my poor old series 3 1980 SWB has sat on the drive with one door off waiting for me to fix it for the last 2 years. and now i have to clear off the layer of moss as well. :o)

"NO MY TRUCK IS DONE YET" @ 0:22, that is awesome!

[@Tinker1837]

Good spot haha!

[@gafrers]

Great to see more progress and "cleanup"

[@Tinker1837]

In the moment these things so seem insignificant, but after I take a step back they definitely are bigger than I expect.

[@percula8]

I retro'd my Defender with the exact same gauges and had the same problem with the RPM gauge. Once you wire your signal from the alt, there are tiny microswitches on the back to set the gauge to different pulse rates from the alt. I played around with the settings until I got it right.

[@Tinker1837]

Ah good to know, figured it would just take a few settings here 'n there until I got it right. And I'm confident I can get it near enough to exact since I have a handheld laser/photo tachometer meter to double check.

[@joekirklin]

So wierd to see you using the Black fuel handle.... Instantly thought, "well theres your problem!" Ours are always green for Diesel.

[@Bread996]

Wait you used the black pump handle?! In WA the green pump handle is diesel, the black is gas. Man I would destroy my truck if I passed through a fuel station like that :)

[@Tinker1837]

Yeah the pumps around here are goofy with no real sense behind the colors... that's why I put so many diesel only stickers all around the fill door so I remember to double check 😆

[@TetovoBoy]

Idiots lights low beam high beam etc btw good work

[@Tinker1837]

I'm honestly not sure yet what I'll do for that... either drill holes in the this cluster for the warning lights + indicators, or setup a panel for those lights up on top of the cluster surround.

[@95Z28A4]

Really, really nice job on the gauges and the project overall! I followed your build on 4BTswaps. I''m pulling together components for a 3/4 ton GMT800 6BT conversion. I have planning to use the GM AD244 alternator, but am having second thoughts. I'm now considering a 28SI. What alternator did you finally end up with? And what thermostat housing did you use? Thanks.

[@Tinker1837]

Thanks! I'm using the original Rover alternator for now, but I'll likely go with a rewound diesel unit later down the road. I used the angled housing to make the custom radiator easier to fit.

[@wesm6422]

What about all the other lights for air bags, etc. Mine has like ten different ones on start up.

[@Tinker1837]

Airbags are not there anymore & warning lights are going somewhere else

[@TheCanadianBubba]

Great looking cluster ! Painting it the Cummins color is a nice touch. What do you think of the old racer trick of rotating the gauge so the needles are straight up at normal operating position ? might be handy if you will be doing a lot of rock crawling or high angle operation. Look forward to seeing you get it sorted !

[@Tinker1837]

Thanks, and I hadn't thought of that idea!

[@TheCanadianBubba]

I have done it, and it really stands out when something is off... great to have you back uploading, thanks for the videos !

[@Dogfish47]

That looks very neat! Are you getting speed from the transmission or from a wheel speed sensor ?

[@Tinker1837]

Thanks! The speed sensor is built into the tailshaft of the trans.

[@georgeaguirre8476]

Love the gauge setup ! Where did you get those gauges at

[@Tinker1837]

They're VDO gauges from Summit Racing: www.vdo-gauges.com/instruments-displays-and-clusters/by-series/vision-black.html

[@claudioespinoza474]

Hello... excellent project... magnificent and I followed your discovery project from the beginning, I plan to do the same project of a 4bt cummins for a defender... at some point I can ask for your opinion... and idea... congratulations ..

[@stephenpenland278]

So at the fuel station the black handle is diesel and the green is petrol. I got to 76's and where I live its opposite.

[@Tinker1837]

I swear every other station does it different here... not ideal & part of why I put so many "diesel only" stickers on the fuel door.

Hi. Your engine RPm gauge work from alternator or another sensor?

[@Tinker1837]

Alternator

[@dohcdelsol93]

Did you you ditch all the disco 2 abs/traction control components? Any issues with the immobilizer without the v8 in there? I'd like to know how you got around all the bcu related electronics.

[@Tinker1837]

I did yes, actually to clarify I ditched the ENTIRE electrical system. Went in there with bolt cutters, was surprisingly cathartic. I'm building my own bespoke system in it's place using a combination of motorsports + mil-spec + marine grade parts with breakers instead of fuses & solar etc. Big job but fun to decide where everything goes & how it works.

[@dohcdelsol93]

@@Tinker1837 I have always heard the differentials were weak on the rovers, the traction control helps spread the effort as to not grenade anything. Did you upgrade the gears and replace the differentials? Also were you able to keep the climate controls/lights/signals/power door locks/power windows functional?

[@Tinker1837]

I did not upgrade any gears, by some luck the ratio's worked out perfect with this engine/trans. They are in the range of 1/2-ton american axles, so not weak really, more the issue is cost in upgrades versus american axles like Dana60/Ford9 etc. Lights and signals I have rewired so they work, and no climate control will be custom as well.
