- Fixing the issue with my P7100 / P-pump throttle lever and finally on to the real road testing!
~ PART#45 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?

Skip to the driving? Here's a time stamp! >>> 06:15
Great to see it being back in working order, glad it wasn't painfully expensive to fix.
I was very luckily unlucky on that pump issue... easily could've blown up my whole housing and cost me thousands. But when build get this deep you have to expect glitches!
I wish I had your fabrication skills and machinery to work on my Suzuki... Great stuff, I love the detail of the builds and how you dont just show success, you also show your mistakes too. The comedy skits at the start of your videos never cease to make me laugh! Looking forward to seeing how the Range Rummins performs offroad.
I think it's a good idea to keep the videos as honest as possible, especially if it will save someone else making the same mistakes!
@@Tinker1837 Keep doing it!
Will do!
Cracking job.
Can’t wait to see this off road.
Thanks & me too... it's way too clean!
cant get over how tidy that engine bay is ! Looking forward to seeing what you do with the rest of the disco
Just don't look too close... my paint skills could use some work haha!
You have accomplished what ever disco 2 owner has always dreamed of.... dumping that terrible V8.
Right! Lots of work but so damn happy :D
So, in your spare time, you could use this beast to move old 747's around the airport! Outstanding!
Rover Taxi haha!
Hell yeah!! I love when the fix is easy/cheap. Can’t wait to hear how it cruises highway speeds and what the mileage will be!!!
SO happy I was able to get it rolling again so easy/cheap!
One can only imagine the custom hood for this lmao
I have an idea for that & I think it will be very unique ;)
I just enjoy watching you drive that around after everything! Sounds great too!
It's been a long time coming!
Congrats finding pump issues!!, Remember to stay idle a minute or so, to warm/cool turbo at start/off !! It´s a must.. Cheeers!!
estudiom142 shocking idea in a derv if you understand cylinder pressure and blow by :) just drive it but not to hard
So glad it was a relatively simple/cheap fix!
excellent congratulations. After the failed test everything went well in this one.
Thanks! Glad it's all working now :D
Loving the videos mate, been following for while now and love how you make the simplest (sometimes more boring) jobs very interesting to watch. Keen to see it on the road! Keep up the great work
Glad you like! I'm always trying to sprinkle in a little nonsense, especially on those more dull jobs.
All video are so helpful of all technical person and mechanics. All work are perfectly with cutting, welding and banding. Nice results of after too much hard work.all videos are most satisfying.
Glad you like :)
The small laugh of knowing something is broke haha! Crazy to think the engine came from a generator!
When you go from "Did I kill it?" to "Oh whew it's just wounded" hahaha
@@Tinker1837 yep exactly haha!
Absolutely love the 4bts. Sounds great and torque-y. You ever thought of changing your rear end gearing? Possibly help with the speed up 😎 beautiful build brother.
Yeah :D And the gearing is nearly ideal for low end but good highway cruising too. I have just been very easy on it since the glitch from last video... was scary!
DUUUUDE! I'M SO EXCITED FOR YOU!... AND ME! LOL
I'm all giddy like a little kid! Can't wait until mine is running as well
It's so damn good! About time this thing put rubber to pavement again, been way too long, but well worth the wait. And it worked out lucky with all this recent free time! It's going to be so cool to see another one ripping around too :D
@@Tinker1837, dude, you'll have to come down and go crawling/overlanding here with us (when I get mine done:D
For sure! I'm stoked to finally have it where I can trust it to travel out of the state without spitting out a cylinder liner haha!
Nice job! That thing looks, moves and sounds amazing!
Thanks! It makes all the right noises & I can hardly wait to lean harder on the throttle to feel the full power :D
Wow the same thing happened to my p7100 pump. Bent governor springs. My fault I improperly installed new 3-4K g. springs. Very impressed you fixed on our truck. I could not find replacement parts so I had to send my pump to get repaired. It couldn’t be fixed. I wore it out running pure (filtered) but not cut or diluted vegetable oil. I had to buy a hole new rebuilt unit.
It was tricky to do on the engine, not to mention hair raising since it's all new to me, but so glad I did it this way. Unlucky issue but could've been sooo much worse!
Congratulations on a successful test drive.
Thanks!
That clutch is suffering asf :D Good job, nice build.
Yeah I suck, but I'm a quick learner haha!
@@Tinker1837 there you go. You're doing ok, but try to take your foot more quickly.
Will do :)
Impressed again with your job Tinker! Nice pump fix...
Only would like comment 2 thinks. First to ask you about roof light. It seems on the corners more yellow like for fog purposes and more white in the center. Is right? Can I know the reference of both please?
Ok second think. I' m a little afraid about your health. I mean that exhaust seems very near of cabin air intakes and near too of front windows. Think that at certain speed all exhaust gas or a part of them maybe can enter on passengers places. Think about it please.
Overall great job again. We are always expecting about your news and progress...
👏🏻👏🏻👏🏻👏🏻👍🏻😷
Thanks, was a real head scratcher since I've never been into an injection pump before. The outer ones just appear that way because the covers are grooved to scatter the spot beam into a flood. I love those lights, they are so powerful! I don't think they make them anymore, but here are the specifications if you can find something close: Aosi brand name, 9" round, 225watt. Oh don't worry about the exhaust, just temporary for fun until I build the snorkel and full exhaust with muffler :)
@@Tinker1837 😷🤗👏🏻👏🏻👏🏻👏🏻👏🏻👍🏻 Glad to hear it (about exhaust question) tnx for info concerning lights!
2 months! Why ya gotta keep me hangin man....🤣🤣
Apologies, but it's far from over ;)
I greet you friend. I’ve been watching your project for a very long time, super, you know how to do great things! According to the last video, judging by the exhaust you have a very poor mixture, you need to add diesel fuel, the thrust will increase, and the engine temperature will drop. But this is my opinion, I can be mistaken))) Thanks for the video, I'm glad that your project is nearing completion, hello to you from sunny Kyrgyzstan.)))
Thanks, & yes it could be a little more rich fuel mixture.
Congratulations! It sounds healthy.
Thanks & yeah it makes all the right sounds :D
cool! now its the time to go off road😋
I can hardly wait to get it muddy... it's too clean haha!
This channels awesomeness! Glad I found it
Hey thanks :)
Congrats man it’s looking awesome
Thanks!
Hi man, great project! I thoroughly enjoy your videos! Keep at it
Thanks & will do!
This is just awesome!
Glad you like!
Tinker, boost gauge too and wait a few seconds before turning off the engine so that the turbo lowers the rpms and doesn’t rotate without lubrications; good job. Greetings from Colombia
Yes & yes. Good tips & thanks!
I can imagine youre looking for heaps of excuses to drive your new rig around haha, "Just going to go get the mail from the mailbox!" *Grabs disco keyes*.
Oh you bet! Lots of "essential business" test drives 😎
The dizel pump is the soul of engien.
Yes!
Very cool, you are inspiring me to get out and work on my jeep more...love the build
It's been a great time to get ahead on projects!
Hey man, longtime without hearing from you. You are well? Al fine? How about your amazing discovery? Hope to hear about you soon!! Greetings from Spain... 😷👍🏻
Hello :) Yes, doing okay. Very busy with things but looking forward to getting back to work on videos.
“I’m your privaaattteee dancer, dancer for throttles, throttle-parts for Land Rovers; do what you want me to dooooo...” - Tina Turner at some point in some song, maybe.
Ha! :P
Hello. Judging by the video, the front of the car body hangs out a lot. Check the condition of the cushions on the body-frame mount. I wish you success in completing the project!
Body mounts are okay BUT the suspension springs are not happy about all the new weight from the engine in front + the camper in back... need new springs soon!
Awesome stuff. great to see it running. Will you be running a snorkel? I'm just wondering if the current set up ( i know it's only temporary) might be restricting your air flow, primarily the large elbow joining the air filter to the turbo.
Snorkel for sure, have a whole plan for that using a fancy Donaldson filtration unit.
consider setting Idle slightly lower, will help low speed shifts relatively easier. at least till you get used to it..
I'll give it a try, just have the idle set up near 800rpm to smooth out the shake.
You should check out the Banks DataMonster. That one gauge can monitor all the vitals of your power plant. Gale Banks has some great videos on what is can do and what you should be monitoring. IE: Manifold Air Density not Boost PSI.
Ok yeah I know it, and Banks is such a legit dude, big fan 👍
Tinker, maybe you should change your rear end ratio to a lower one to improve torque. The ratio of the gears seems faster. Excuse me I don’t speak English; greeting from Colombia
Gear ratio's are good, just not driving fast :)
Next video short shift into second and roll into WOT. You're just teasing us with this lol.
I have to admit I was afraid of what happened last time... taking it easy and keeping it close to home base!
You're a genius bro, but now to the interior haha 👍👌
Thanks & yeah I really need a dashboard!
Can’t wait for the next one
Lots more to come, and finally getting to open up the tap on this thing is glorious!
muy hermoso ese pueblo, parece un set de cine....
It is a small town that does not mind farm tractors driving down the roads, so I can drive my Land Rover tractor on roads without upsetting any people haha :P
Find the highest torque rpm range. Example : it is
- 1500-2500 rpm in my Nissan diesel SUV
Upshift at 2500, downshift when 1500
If you drive in constant speed, try to adjust your rpm around 1500-2000 rpm. If you accelerate, increase 2500 then upshift and so on
Good info 👍
@@Tinker1837 Thanks Mate 🤟🏻
Hey mate! Wonderful work you’ve done there. I was wondering, how’s the divorced transfer setup holding up? I’m about to do the same kind of setup with 6bt in a GQ patrol. 😁
Thanks! So good so far 👍
you should enter the IQCS 2020!!!
If it wasn't for the pump throttle linkage issue I sure would have! I just missed out on the deadline since I was burning daylight on the pump fix.
Good work my guy!
Hey thanks!
Don't slip the clutch between gears. Great job.
Yes sir, & thanks :)
Just spitballin', but the yoke on that linkage looks a little thin at the upright, 3:38+ looks like it had been wearing for some time. Bet you that the temperature will come up on some long grades, or in the summertime. What is it about the transmission that is so different ? Great days to you and yours, you must be stoked with how it is shaking down. Pretty minimal dilemmas considering how much work in so many areas and systems you have done !
Even the new one seems thin in the material between either leg of the yoke & the stem of it... but from what I can tell it's not from wear but cast that way. I'm beginning to wonder if somewhere in the process of building my throttle cable mounts / bracket if I managed to crank on the shaft or hit it with something to cause this. Because the more people I ask the more rare it sounds like this failure is. Oh for sure & I already have fans, just need to build a shroud to hang 'em. It's not so much the transmission is different as the whole thing is, only ever driven a diesel twice & it was far from your run of the mill truck. I've just been into real high revving imports for so long that this whole "shift with no throttle input" thing is throwing me for a loop. Yeah these sorta speedbumps are something I expected & if this is all I encounter then hell yeah I did okay haha!
Thanks for the great reply, look forward to seeing how you will finish it up !
So what's your plans with interior and the hood are going to put automotive stile switches for the lights and ignition and stuff
Oh yeah, those house switches were just for fun / temporary. I'm going to reinstall the dashboard & do a really in-depth electrics build like something you'd see in military vehicles/aircraft.
Damn good job wouldn’t have done anything else different
Thanks!
My friend ... people want to continue Disco
Yes yes, soon I hope
Wheres the new installment!!!!! We demand more
More on the way!
Great vid 👌👍
Thanks!
Dude thats so awesome...... you said you have low oil pressure, what was it reading?
Crap, did I say that in the subtitle? Thought I said steady or something, guess I better check because that would be pretty confusing (it's a healthy 60-80psi)
@@Tinker1837 my bad I read it wrong lol
Oh! Whew. That could've been mad confusing if I flubbed up a subtitle like that lol
@@Tinker1837 lol im sorry man...I just got home from work and am exhausted but saw you uploaded a new video so ofcourse I had to watch lol
@@Tinker1837 was an extremely busy weekend
This is what I had to deal with on Sunday
ruclips.net/video/cEHA9xpQ2TU/видео.html
Got any progress on this beauty ? I hope you make a video about electrical wiring.
Not a lot lately, but updates coming soon. Oh yes, and I'll go into great detail with the electrical build.
Stupendously Amazing
So happy to have it on the road!
What year NV4500 are you running? Also any chance you have a part number or year range from the bell housing? As well as which adapter plate off of the engine do you have. Finally looking to mate up my 4bt to a 94 Chevy NV4500 but I know its gonna take some additional tweaking to make work.
The year I'm not too sure, since it's a hybrid built from new & upgraded parts. The engine side's based on a Dodge 4x4 Heavy Duty Diesel truck with the big clutch + big bearings, & the tail's based on a Chevy 2x4 Heavy Duty truck. The bell housing is the Advance Adapters part meant for the HD Dodge diesel (with big clutch/flywheel), & the adapter plate is the same (from a 6BT Dodge).
Look on the clip of your Watergate actuator you cant be creating enough boost because it's not even moving on mine I have the exact same actuator granted I have a little bit of smoke mine moves free reving a little bit
It doesn't open until 28 psi, & I was not pushing it hard enough to crack the wastegate open after what happened previously.... soon though!
I don't remember, did you put hydro-boost brakes in your Disco?
Not yet, but it's on the list!
Me alegra que ya funcione!!!!! te preocupa la temperatura del motor? sabes aqui en argentina hay una empresa que fabrica portectores de motor ante alta temperatura y baja presion de aceite, ante un evento de estos detiene automaticamente el motor y no lo dañas. si quieres mas info solo levanta tu mano? buen trabajo!!!!!!!
Me too! And I'm not worried, because even after driving all day the coolant temperature never exceeded 175F / 79C
@@Tinker1837 deberias ver a que temperatura trabaja el termostato, quisa esa sea la temperatura de trabajo correcta, muy a menudo estos marcadores son un poco engañosos. Aca corrobore en el catalogo de los protectores de motor marca "vigia" fabricados por la firma "colven" y para el motor cummins 4b TI la temperatura tiene que exeder los 115º C para que se produzca algun tipo de daño
Good info! I will check on those.
Hi Tinker! A lot of time without hearing from you...
Hope all well.
Is possible to know wich model is the roof of your Discovery and the 4 lights there? A pair of them are fog lights? I'm interested in and in the roof for my Discovery. I hope to find it in Spain. Greetings 4 U from Barcelona 😷👍🏻🤗
That's a Voyager roof rack & the lights are Aosi brand 225W LED's with interchangeable fog/driving covers (but I don't know if they are still available)
@@Tinker1837 Thank you buddy. When you have for sale autocad, solid works or so plans for the rear furnitures and appliances please let me know for buy it. I will introduce in it some modifications for mi Discovery 300tdi according my needs and I would like to made it. 👏🏻👍🏻
Did you have any problems with vehicle inspections since you converted to diesel in your state, the engine has to be the year or newer than the vehicle and tested by the year of the vehicle?
Thankfully I did not, since Michigan has no requirements for that sort of thing.
So how did that thing break in the first place? I am a total noob but are you worried it might happen again or was it just a bad part to begin with? The driving looks so good dude
Wish I knew! But I suspect it was something that's been cracked since well before the install since it had 5-6 years of sitting around before I refreshed it & started it up. Taking it easy for now but it's still so fun!
@@Tinker1837 Right on! That makes sense
Ever thought if messing with the star wheel or grinding / taking out fuel plate
Oh yes, in fact I've fiddled with literally every component in there. I still have plenty of fine tuning to do with turning the star wheel, adjusting the smoke screw, sliding the afc housing & plate, bleeding off the wastegate etc. BUT I did already grind my own plate profile, modified the AFC rack & swapped washers on the diaphragm for more fuel travel, 4k gsk, etc. Lots more power potential when I get head studs & injectors & fire rings >:)
Tinker gotcha I’m excited!
I've been kinda stunned how lucky I got with my "base tune" settings & how clean it runs, but a little more rich couldn't hurt. I'm not afraid of a little more smoke to keep egt's happy 😎
Tinker lol from all you’ve said I’m very impressed as well... I would say you very well have tinkered with most of it, yet still no smoke I guess if you want big results bump the pump but then risk heavy running heavy timing and possibly running away. All in all I know you will do good!
Yeah I'll take it a little easy on pushing power until I get the head studs installed (maybe fire rings too) but then I can get the bigger injectors in there & bleed off the wastegate so the turbo can breath past it's original 28psi. I already have the timing cranked as much as I think is safe (14.5deg if I recall correctly) unless I get a bigger pump, which I think is probably why the bigger turbo is working so well with the engine so far.
Why do you push the accelerator when you start? Doesn't 4BT have "infinite" low-speed torque? There is no sense for swap 4BT if you need to push the pedal.
Because I'm stupid... and still learning :P
She's some rig lad
Thanks, it's a tank for sure
excellent work🇵🇷🇵🇷🇵🇷
Thanks!
I'm sure it will doughnut when everything's adjusted! Will you need a hood bulge or does it fit as standard?
Center-axis 4LO donuts in this thing would be nutty! Yes, plan is a cowl added to the hood with a few unique features to clear the tall intake + turbo.
@@Tinker1837 I'd be tempted to make some type of ram air scoop leading to a cyclonic pre filter with no loss of suction! Lol,it would spit out water and debris before the high flow filter,just thinking about wading without a raised intake? De-selectable rear wheel drive would be good for climbing ledges at brakeover point to stop backflips !:)
I'm looking forward to the intake/snorkel build, and I love the idea of modifying the LT230 transfer case even more than I have so I could maybe "twin stick" it! I have an old NP205 case that's setup for that, but the LT230 has a center diff (since AWD) so it could be a little more tricky.
You say the brakes feel great without the abs? Because I've always had a soft pedal on first pump i have all steel braided lines and even replaced my master cylinder and haven't felt any better i would hate to keep throwing parts at it if it's never going to get better
What size you go with? AN-3 or 4? I've gone a size up by mistake before & had that problem. I plan to custom mount big Range Rover Sport calipers (6pot fronts & 4pot rears) so I'll be going stainless AN the whole way eventually too.

@@Tinker1837 I'm thinking i may have a sticky caliper
Huh, so sizing isn't the issue, hopefully it's an easy fix like a caliper.
Nice work. 👏

Lucky that my initial tuning was so clean!
Time to turn it up so we can see some coal rolling 😂
More pooooowerrrrr
Good Job 👏🏻👏🏻
Thanks :)
that exhaust it is right where you get your ventilation
It's it temporary, just for fun until I build my custom snorkel & dual stage airbox.
Love this 🤓
Thanks, it's fun :)
She sounds good👍
Only way better would be with compounds... but I'll get a season or two on it before I get started on that haha!
Tinker Do you have any idea how much horsepower it’s putting out right now?
Stock was 110-130, now around 225hp & 550tq
Tinker wow!! Not bad at all!!!👍
I'm already getting excited about the upgrades that'll pump it up way more too (injectors, fire rings, head studs etc)
I literally just blew my engine TODAY! And I have stimulus money, how much to do mine like this! Lol #Help
It's a shame these generation Rover V8's just don't hold up :( I wish I could've figured out a way to make a "kit" for this install, but the way I did it just requires too much fabricating. And it depends how you do it, if you keep things simple & you're patient you could swap like this for ~$5000, or if you get carried away with mods like me it can cost nearly ~$10k lol
Search tiny tach. Was my cheap solution , and damn it works well. Did I mention it was cheap lol
Good tip, I'll look into it!
What are you going to do for a hood?
Dönald Trümp try for a 77 Range Rover hood
I've got a clever idea that's a nod to the old school for the hood clearance issue, more to come on that soon!
good
:)
I need more content! lol
I've been slacking!
Nice
😎
Good work
Thanks!
What are you using for the snorkel and air filter?
I'm building a custom setup that I'll fabricate to run up the passenger fender & a-pillar, using a Donaldson sealed dual filter system on the same side of the engine bay 👍
Hey man adjust the turbo exhaust safety open valve to get more boost
Oh I know but ~30 is plenty for now, at least until I can put head studs or fire rings in. Then to the moon!
Ok bro I didn't see your previous videos great efforts bro what you did is perfect
Sounds so juicy!
It's so good :D

Wish this was an auto, mated to a sweet diesel would of been mega. Sounds the business tho! Any idea on HP?
110hp probably...
I'm not a big fan of autos, except for drag racing. But it's around 225-250hp & 550-625tq (from known build recipes, not a guess)
@@kealahau6727 LOL nope, was more than that stock :P
Me too im over driving manual specially off road on steep obstacles too very scary driving stick on steep muddy hills
I've been practicing my footwork for years now (left foot braking & heel-toe) and thankfully this thing has torque on tap so you don't even need to give it throttle into gears, but here's hoping I don't regret going with the bolt-action trans!
Классно 👍👍👍🚐💪 Discovery на ходу...
So happy it drives finally!
Good..
Thanks!
You never said what caused all that damage to the pump ??? .
I wish I knew why!! Best estimation I could come up with all the input I received was something was damaged/cracked before I even installed it, perhaps when the mudpump I got it from self destructed it's pump gears, and it just didn't rear it's ugly head as an issue until I actually put some load to it with that first test drive.
Try not to lug the trans. Nv4500 isnt a fan and will eventually causes some issues. After some reading on dodge forums and so on, most people up shift around 2200 and try not to run down below 1300.
Very much yes! My terrible shifting at first was a bit embarrassing, but I've always included my mistakes. Also doesn't help that my other manual trans vehicles are SO different than this thing.
@@Tinker1837 im learning it too man, i just happen to have a nv4500 that has a failing 5th gear that lead me down the road to learning this info. killer built, really cool to see.
@@walt3r88 hey man, I'm late to the party but there is a simple fix for the 5th gear issue. I had a shop fix mine. If memory serves, it's just a locknut or jamb nut. Happy cruising.
