My ZD30 Turbo Boost Pressure and EGT Gauges - [ In Real Time ] 

Very good vid Tim, thanks mate. I left the Patrol badge behind when they went the 3.0L , but with those mods you seem extremely happy with your Patrol. Bought it from new too I seem to remember. It’s great to see you are still loving your 3.0L. Cheers mate. 👍🍺

Thanks a lot for the info, I have an 02 Nav, ZD30 DI, just had an engine rebuild, With the new build I added: 1. Gauges 2.glow plug momentary switch. 3. Swirl mod & Egr block. 4. Ecu remap. 5, 3” exhaust 6, stage 2 turbo(nav&patrol are different turbo set up). 7, 30th over injectors. 8, large front mount intercooler. 10. Quality catch can.11,snorkel. Egr runs pretty cool , it boosts pretty dam high and have to turn it down, 25psi, I don’t know the hp at this time but guessing 200s , the only issue I’m having is coolant leaking from the thermostat housing when using boost up and down the gears , highway driving not coolant loss, I’ve use an non original thermostat with an original seal, I’ll update the Egr and boost soon.

Awesome watch.. I found after adding a Safari chip, the boost stopped spiking which will shut down the boost, and need to reset letting go of the accelerator while driving.. that's problem is solved. With some more power added, trying to keep it straight in the wet is a new problem. Thanks mate

04 DI ZDeeeeee. Only got welded standard size cooler. My old girl got close a few times to 500 tonight towing my 7x5 with a full load of wood. Gotta baby her along. I would like to give her a bit of mod love but I dont think ill be holding onto her for much longer... Family is growing and the minister of war wants something a bit safer on the road. Always enjoy your content Batesy very down to earth and easy going..

Good stuff Timbo. It’s always interesting to hear what other fellas trucks are doing. My TD42 will sit on 240° egt on around 4psi @ 100km. Very modest numbers. It will barely flicker 350° up hill. Really happy. I highly recommend EGT/BOOST gauges too.

I have a 2006 ZD30 patrol, I have a high flow cat, Seletron tuning box 30+ hp and heaps more torque, I have a custom welded intercooler and large Godzilla scoop, i do work on patrols here, have worked on plenty of these engines inc heads and diesel pumps, a new rad and tensioner is a always a good investment on higher k examples..i have EGT, boost gauges and i fitted in my opinion the most important gauge on top hose of rad an alloy adapter for dash mounted digital water temp display gauge which will tell you if you ever have a coolant leak as temps will creep up if it starts to go a little low!! Full EGR delete and those small coolant hoses to EGR which are dangerous if they leak and they only add extra heat to the coolant system. Best mod I done of the lot is a full AC and condenser delete, the amazing thing is how fast the EGT's drop sinse i deleted all that crap, imo it's important the duration of sustained EGT temps and how fast you can drop those egts extremely rapidly once the AC is deleted, With AC it's very restrictive to the radiator. I tow 4cm³ of firewood every day as it's my business, weight is 7.5 builder bags plus it's a big 9x5 trailer with very high rails !! Up hills towing max foot to floor for a long time max temps I ever saw punishing it was 400 egt and 94 degree water temp. I am in Ireland so the AC is not important here for the two days of summer we get😂

G'day Batesy, with a similar set up getting very similar numbers. The bigger intercooler certainly helped with bringing those EGT's down.

Hi Tim, I drive a GU td42ti in stock form and never had overheating problems with 360000k and still have boost and EGT's gauges and a full set of water, oil, temp, on it, it all boils down to how one drives, thanks for the info.

Thank you for you information

Highly recommend putting a Fatz airbox in Tim , afr,s and boost response will be even better, my gu td42 at 100 - 6 psi , 267 egt 🤠

Mechanical sympathy is the key Tim

Good stuff Tim. I used to get similar numbers to that in my ZD30 Navara, non intercooled. I'm guessing they have the wick turned down a bit compared to the Patrol. I actually just sold it with the odometer at 375 000km and still going strong. I now own a TD42 powered Patrol and watch the gauges nervously on steep hills, something that was never an issue with the ZD30. Cheers Sean.

My 2003 ZD30 at 100kph at around 12psi I get about 240c. Only mods are bigmouth bonnet scoop and 3' exhaust with hi flow cat and no muffler.

Awesome as tim 👍

Hey batesy. Great numbers you are getting in the gu. You will be horrified at mine. Iv got a series 5 crd auto gu with factory turbo after market intercooler which still fits in the factory scoop and 2.5' to 3inch out exhaust. My numbers at 100 on flat about 400-550 weather depending at 11psi. As soon as you go up a hill it will go straight too 600 and on the longer hills it will hit 700 no worries if you don't back off. Yeh not the greatest numbers!ha

I have heard that people have also been successful in dealing with the overheating by installing a high flow water pump. Out of interest what did you remove from the car to reduce the weight?

Would be good to see the difference between staying save but pushing it vs your normal drive.

LOL, 240°-250°C @ 100 on stock snail and tune. Your choice to pull back on boost will see EGT's rise. A hot and heatsoaked top mount IC isn't doing much, especially at town speeds.

very helpful thanks

Hi Tim. Love all the GU vids. I am looking at installing EGT and Boost guages. Do you think the SAAS guages are good. The Redarc ones seem very expensive.

Hello tim, nice to see you again. I was thinking about you and the EGT last night, and how you wasnt sure on what the stock EGTs would be. In fact, i have seen a stock EGT go up to 700C, no remap, just stock zd30, but that was on a direct injection. If you want to find out more, just go on youtube and tyle in nissan patrol stock EGT. Chears and nice to see you back

Thanks Tim - have you got any dyno numbers for your tune? And should you actually put the pedal to the floor, what EGT/Boost numbers are you hitting? I ask as my tuned ZD30 has very similar low ETGs on the flat at 100kmh running a max 20psi on original turbo, but living in Tas and towing camper/caravan find it easy to push into the 600s if I'm not watching.

Awesome video Tim quality gauge for egt is crucial for sure where do you put your egt probe dump?

Where is your probe located? Before turbo or after? It looks like yours is after. You would see about a 200 degree drop across the turbo in this case. The point of all this is to get an idea of the exhaust valve temp but that's impossible to do directly so there needs to be some guess work. If you see 400 deg after then that's about 600 deg before the turbo and add about another 100-150 degrees to that to estimate the valve temp, so about 700-750 degrees. Which is fine but you can see how people run into trouble getting 550 post turbo as they quickly reach 850-900 at the valve which is pretty much at the limit.

Tim, I have a 2005 GU ZD30 Direct Injection Patrol. I recently replaced the engine after a failure. Can you give me any idea as to what the vacuum readings (to the Turbo) should be for the engine whilst it is at idle? I have an adjustable Daws Valve fitted however I cant seem to find any figures re: setting it at idle.

How is the intercooler temperature controlled? Where does it take the temperature input from, the coolant or a intake air temp sensor?

Hi Tim, luv you videos. I am ex marnie mechanic from my service in the Australian Navy and later on with merchant ships. I note that you have an upgrade on your Nissan ute. Was that necessary upgrade, these marnie engines are Caterpillar, Cummins and the larger ones such as MAN B&W . We didn't do anything to enhance there performance either in warranty or not. Why are boosting efficient, it will only increase cylinder and piston wear and place more stress on the bearings of you engine ? Best regards Ray

G'Day Tim ! my 02 ZD30 Di Dyno tuned 16psi and at 100kmphr towing up big hills will reach 550c max .usually sits around 350 450 .. would you consider upgrading all your intake piping for more efficiency? Cheers mate, Brent !

What litres per hundred do you get, I haven't had much to do with zd30 fuel consumption but my brothers is around 8.6 '8.9 @ 100kph, we fitted a billet compressor wheel turbo, with 3" exhaust and throttle module, curious as to what is considered average for patrol

3 L Hilux 2014 ETG 350 on the flats going up hills i’ll stay under 450 Court tap 85 Oil pressure Cold 65 when the motor is hot about 50

What's the gauge below the egt and boost gauge? Oil temp? Water? Cant quite read the markings

Hi Tim I’ve got redarc gauges how did you get the digital reading my gauges are duel oil/water egt/boost and duel volts

i have a zd30di when accelerating up to 100 itll hit 550-600 depending on certain elements. cruising speed itll sit around 350. what would you say the best thing to do to drop them temps so it doesnt blow up. it has a bigger intercooler but im considering a 3' exhaust.

Geez im well high of that, i sit around 400 450 egt 100 k's 07 zd30, 550 600 working up hills loaded and reduced speed, best i get mine tuned,

Hey Tim, have you had any issues with coolant leaking behind your timing cover on the zd?

Hey Tim. I got a 2007 GU ZD30 yesterday, is now awating RWC. Fortunatle/Unfortunately the car already has a few mods so I won't be learning by doing, I will have to learn by investigating. I already set up a playlist of your videos, but if I may ask, since I don't have a owner's manual, could you do an explanation of the dahboard buttons, etc.. Google is not helping. I understand if not the type of video you make. But basic Patrol functions is something I am struggling to find.

Thanks mate

what's the switch below the gauges do?

What about at 110 km/h ? What are the readings then ?

Hi Tim where did u mount ur egt sensor

G'Day Tim Were you in Bairnsdale on Saturday ( at Coles). Cheers Rory

Hi Tim Did you install the gauges yourself? Cheers

I got a 2010 110klm I get mine up to 550

Don't be scared give her more boost and more fuel those numbers are so underwhelming

Not trying to be negative or burst your bubble Tim but have you looked into the new Scangauge 3 ? I was going to get one of those pods and a couple of gauges, but when I crunched the figures pod around $100 plus and each gauge is around $120-$130 so you are already up to around the $350 mark. A scangauge3 has a possible 27 read outs, 3 pages with 9 on each page. So instead of 2 read outs I can have 9 in front of me at anytime with a glance. From EGT'S, Trans temp, water temp, boost, and so much more and not far off the price of 2 gauges and a pillar pod. Any way cheers and keep up the great work... love your content... Laurie.

Got my gauges few weeks ago and keen to have a crack at doing them my self , but also apprehensive tic find out my numbers 🥲😆
