D40 Navara High Flow Turbo & 3 Inch Exhaust Dyno Tune

In this video, we install a high-flow turbo and 3-inch exhaust to our yd25 d40 Navara, and then we head down to BB garage for a tune.

So all I need in order to install a d40 turbo onto my D22 yd25tt is the manifold, turbo, dump pipe & intercooler piping? Thanks man your vid’s shed a lot of light on the Nav scene. Trying to get some decent power but it seems mods for these are pretty scarce beside small package upgrades.

Great video man! What’s the mileage on the Ute?

[@horoshii_chelovek093]

hi, I have an NP300, I want an increase, will replacing a warm impeller be enough?

[@FinerDetailsWindowCleaning]

Awesome work! I have the R51 with the 140kW YD25. I already have a 3 inch Stainless exhaust fitted. You reckon I could get those sorts of figures out of my engine with the upgraded turbo and maybe an intercooler upgrade? Which intercooler do you recommend? Thanks for the inspiring video!

[@yd2532]

Yes the 140kw models can also make good power. If you buy a decent intercooler and get custom piping made it would be better then the kits

[@the510wagon]

Once again, great vid mate. Really enjoyed it. I'm following this series closely because it's exactly where I'm at with my D40. I'm curious about why you chose the piggy back boost controller (Ultra boost module) over a regular remap of the ECU? Did you also remap fuel and boost tables in the ECU ?...or does the ultra boost hold all the modified maps & tables? I'm currently running a Tillix valve for manual boost control. It's old school but it works really well and the boost curve is smooth & consistent. I'm hoping I can keep the Tillix and get the ECU reflashed to suit. Then I can increase above 21psi without hitting the fuel cut/limp mode. I like it because it removes the shitty BCS from the system, which increases reliability IMO. But I need to talk to local diesel tuner - he may prefer to reconnect the BCS for dyno tuning...?

[@yd2532]

with the piggy back can run more than 22psi on the stock map sensor. the ultra boost holds all the modified maps and is a lot easier to make changes to then a remap.

[@ryansilva4790]

That's what i wanted to see! To get that 200 to the wheels, do i need to worry about my automatic transmission and gearbox?

[@yd2532]

havent realy heard of anyone break them should be fine. High flow cold air intake is also recommended. That alone makes 6hp difference without adding extra fuel and helps the turbo not overspeed. Stock intercooler is good but if you do upgrade make sure you get one that doesn't cause anymore pressure drop through the core then the stock cooler.

[@dylanralf9524]

Looks like a great upgrade, what are the specifications and where can you buy?

[@yd2532]

We had them built by gcg turbos. You can buy from them or we can supply them

[@aussiebevo103]

Hey man, do all D40's with the YD have +30 injectors from factory? I have a 2013 Spanish built. Love the content too. Keen to see what happens to this D40

[@yd2532]

Not sure about the 140kw models i'd assume they would with just a different spray angle to suit the different piston bowl designs in the 140kw engines. They dont seem to blow as much smoke as the early models but that could also just be because they have a different turbo and tune

[@aussiebevo103]

@yd2532 ahh yep fair call man. Mines the 140kw variant. I haven't seen too many of them sooting along either

Just picked up a cheap 2008 spain built d40 at the auctions, really low kms on it. I'm looking at a new exhaust and snorkel. Reckon im going tk do the turbo as well now. Did you upgrade the intercooler?

[@yd2532]

we did but for some reason didn't see any gains even tho it did reduce intake air temps and seems to not have any pressure drop through the core

[@fernandosanchez5674]

In Chile, on the D40 Yd25 (175hp), the turbo pressure sensor only reads up to 21psi. How can I solve that?

[@yd2532]

Piggy back ecu I think some people can also fix it with a remap otherwise they use a valve to trick the sensor

[@wickedduck8762]

Hi, I have a 2002 d22 133hp, non commonrail I believe the temperatures here range between 5-15c in the winter and 20-35c in the summer what oil would you recommend? I've taken up the car recently and my father's been using some 10w40 im unsure if it's fully synthetic.

[@Ktmfan450]

No common rail? Go to your local chip shop and pinch their used oil from out the back Just remember to strain out the crusties

would like to know costs? as i have a 2010 d40 4x4 6speed and needs more low end power. loved the 417hp yd25 build

Just doing a tune if you haven’t already makes a big difference

I have a turbo on its way out. I just found this video. Can you sell this setup as a kit? And if so what sort of money are we talking?

[@yd2532]

We can supply the Turbo it costs around $2600 with standard bearings or extra if you want the upgraded thrust bearing. Exhuast came from ppd and cost around $700. Depends on your tuner wether they will be able to fit a piggy back ecu or will just do a remap

[@forgottenknowledge8917]

Always run a pipe off the turbo and nothing else. You'll notice the difference. Cats and or DPF are always blocked on high kilometerage diesels.

Going to a three inch will give you more gains than removing the cat Euro4 doesn't require dpf

I checked out the snail prices, fark me. Bloody expensive huffers. As for tuning, the last run at 30PSI, clearly the turbo was well out of its curve with drive pressures over 50PSI and the smoke, yeah, leave the soot for the tossers and flog-bags, roll that shit in front of me and you would get a spray you would not want.

[@yd2532]

Agreed turbine is the limit for this setup. We are currently seeing options for a high-flow turbine wheel. For now, our plan is to optimize the intake with a cold air high flow intake as the stock one has 2psi pressure drop, an upgraded intercooler, and an upgraded exhaust manifold.

Ye I wanna push this turbo hard then when I get a bigger turbine wheel get the turbo builder to check it for wear so I can see what's the safe limit of it is

[@user-cc8gb1zo8m]

@@yd2532 it doesn’t really work like that. Once the turbine wheel is choked, it won’t flow any more, no matter how much more pressure you have. The only wear will be on the compressor side due to shock erosion. I suspect the clipping of the turbine wheel (if it is) will have a lot to do with your high back pressure.

[@yd2532]

@@user-cc8gb1zo8m ye the turbine is the limit of the setup. Having a high flow intake helps it a bit . The stock airbox has 2psi pressure drop so to compensate the turbo has to spin faster to reach target boost pressure which closes the vanes more and adds to the back pressure

[@matthewmcinnes3259]

That's it... boost doesn't mean anything, only air density.

[@10GTE]

I noticed that too, the back pressure was good at around 20psi, at 30psi though it was in the 50's high in the rpm range. Surely there's a larger frame vnt that can be mated up and produce the 300hp without being too laggy
