Love watching your work and enthusiasm. I'm a 71yo fan of your channel. I've had my GU TD42t for 30 years and it's my treasure. I've set my 99 gu turbo up with a couple of cheap intercooling options via fleabay. Barrel 10x4 or in my case a bigger cubed one rated to 600hp 😂 It's fed by a heat exchanger up front with a 12 inch fan, plus water pump. Pumping cool water up into intercooler. It's a cheap option all up for under 500 bucks I run 14.5lbs boost. As you know..the factory airbox is restricts air flow from the snorkel. Fuel Economy is always great. Mine is primarily used for touring. At 100kph average EGTs 250. Pushing hard up hills it rarely reaches 400 plus in normal conditions. At 90kph to 125+ it pulls like a train and just keeps running on. Its never been flogged past 3000 revs in its life either. All the best 🙏🍀

Just upgraded the Ht18 on mine and also did a whole heap of supporting mods. It goes to mechanic next week for a tune and new injectors, after 310000 kms my car has never skipped a beat and now is running better than ever I have done a lot of the work my self too so I have really enjoyed watching games you guys do this project. Hope to see you out in the high country soon
Mate turn the fuel and boost up a bit more, will actually help get your egts down with more boost and won't be getting as hot with the extra power with the fuel aswell, can't kill a td with a stock pump and turbo maxed anyway. 3/4 turn of fuel and around 15 pound boost will be alot better to drive
A few comments down Zach mentioned injectors, this I would do when playing with fuel. A weak injector will Crack early with a poor pattern, meaning one hot cylinder not being reflected by egts. Cheap insurance! I'm enjoying watching you build up the old bus! Needs a coat of raptor now....hint...
You need to watch your boost gauge give her a quarter turn more fuel and watch your boost gauge and look at the black smoke boost gauges are so important in telling you how she is going it won’t do any damage it’s how we new how our race truck was performing cheers and good luck Dan
those 4.2s sometimes have a filter in the injector pump under the main banjo bolt feed that never get cleaned and can hold them back heaps could be worth to check it
Before touching the fuel screw, set the pump timing to suit the turbo. Cheap tool and simple to do. I have always worked off .76mm btdc, seems to be the sweet spot.
Be really interested to see what difference an intercooler would make. All positive I think, it's why they're fitted. It'll give you denser, cooler air into the engine so your boost makes more oomph. That's not to detract from your great efforts and presentation here. Superb and thanks for sharing!!
I got my td professionally tuned and made soooo much difference in egts and power would highly recommend mate. Payed around 350. Money well spent. Mines a wagon!👍🏻. Awesome stuff dude. Would love to see the difference now that you have records of where you are at now. Great vid
Just letting you know, that circle thing on the intake elbow is a pressure relief valve, I believe it opens up at 14psi. You can block it off with a brass bung from bunnings cost like 5$
Get a cheap ex GU top mount youll drop 150c off those EGT's.. Sounds good too mate! HT18's sound excellent even if they arent the most efficient blower
Remember James's ute also has more fuel, an intercooler, free-flowing snorkel and more boost. You should try and find a cheap intercooler and a bonnet scoop somewhere.
Like you said , they're not for racing , i've just put an intercooler on my GQ TD42T and gone from a bigger Safari turbo ( needs a rebuild ) to a smaller factory GU turbo with only 10 pound boost but haven't had a real chance to test it because my brakes need doing .
My td42ti Gu with the factory tiny top mount egt daily driving freeway hill whatever temps would hit 450 and keep climbing I put a front mount on it my egt never even see 300 on the same tune and that’s towing everything wish I done it sooner
You need more boost and fuel dude! It will bring your egts down and it won't hurt your engine. 15-18psi is the ticket Front mount would be a big advantage as well but can't get away with not having one. As well get your injectors checked/reconditioned Love the videos 🤙🏻
Hey mate the reason it idles high no soot is there is a threaded rod on other side of pump that needs to come out That drops ur revs as u wind in the pump (I’m terrible at explained that aha but can show u a vid if u meed
It'd pay to put a tad more boost into it when I had my old terrano td27t with the ht12 I gave it a quarter turn and upped the boost to 15 it went much better used less diesel too.
Hey guys, this is the 3rd time I've asked. Maybe you're too busy filming but can you please let me know if you can get mech sizes 5xl or larger even if its a special order? I've got mates that will buy them. Thanks
Trust me mate a FMIC off eBay will make so much difference. Much cooler egts, bit more power and acts as a catcher too incase your turbo shits itself. Your car would love it, it’s not the amount of boost that kills td42 it’s generally people over fueling the shit outta them but anything below 14psi for your na blacktop and it’ll last forever bro, good job.
I’m a bit behind on your specs for this, is the engine stock, as in original ks? I was thinking of doing something with my 93, td42, engine has about 260ks as it not original, gq is similar to yours with leaf springs all round and 450ks on the chassis, I’ve owned it for fifteen years so not eager to be rid of it anytime soon
You will feel the difference uphill on a load. Remember it's a commercial vehicle. It's designed for carrying loads not zippy acceleration. You will tinker to electronic and intercooler as its addictive over time.
@@jasper287 you can do anything with enough money. Id keep it mechanical but it can definitely be done. If you can do it to 60s petrol v8s you can do it to a td. Now before you go ape shit, I'm aware diesel and petrol are completely different. However efi on a diesel exists via electro pumps (might even go by another name) especially when it comes to ecu mapping etc
I’ve got a factory turbo intercooled GU 2004 and I’ve left the factory inter cooler alone. It’s runnings 21psi Max, sounds like a lot but most of the time I don’t put my foot in it that deep to let the boost get that high, it will only really get that high on boost on the freeway. Most of the time She’ll do 5-10 psi, put my foot into it a bit more it’ll do 15psi. Can do 110 up pentland hills and won’t get hot either 👍 doesn’t go over 500
Mate, there's no harm in more boost with those non-boost compensated pumped engines. in fact, you're probably doing for damage than good. Diesels run cooler when lean and the turbo will only produce as much boost as you feed the engine fuel through that screw. Disconnect the boost line going to the wastegate and you should get a few extra psi before the gate opens but you should also notice egts dropping a lot.
Yeah don’t just disconnect the waste gate, with a ht18 you’ll get over 20 psi roughly anything that high with that turbo is just insane amounts of heat. He should get a boost adjuster in the waste gate line. He should also get an inter cooler
@@toms_gupooe The exhaust pressure will still open the spring though lol. You'll only really get a couple extra psi over the spring rating. Also it'll only produce as much boost as you give it fuel.
Yeah 11psi boost was the factory. Give the screw another 1/8 turn. Using your camera at the back of the car watching for black smoke is the best tuning tool you can use
Loved the video as always. Quality content here on the tube. Surprised you didn’t get a 3inch dump pipe? Usually people love them for extra power and lower egts
Nice work be careful tuning is the biggest to keep a good eye on it and dyno them after I blew it up when I bought it it came from the west strokes td4.2td so 4.5 litre it was already tuned to (275hp 750nm 34psi boost) but a bad tune it was way too lean down low and mid range then over fueling to buggery at boost lifted and cracked the head grabbed a liner split the block. ( I Didn know about needing head studs instead of bolts over 20pound boost) I learned quickly So thanks to Brett and the team Southern Engines Kembla grange they did a full re build for me with a awesome tune 24psi now head studs in for protection needs over 20psi especially when towing . (261hp at the wheels) egts dropped by 100degrees carnt stress on the tunings it’s a cost saving if you get it wrong and blow something up crack a head etc it’s costly Safe tune heaps of grunt and decent air/fuel ratios now thanks to southern engines.

@@KillerRingNeckParrot What power is it making at that? I put mine down to bad build and tune by the performance company that originally did the build.

@@KillerRingNeckParrot nice and a awesome tune makes then a pleasure to drive keep up the great work. The td can be a great engine when tuned properly and with the right turbo/ pump Set up
Why so conservative? I had my original 10mm wound in so far I i had to do some filing and add helper springs to get the idle to an acceptable level. Double NA Hp and wasn't that sooty, little bit down low but just back off a little down low.
Try to get hold of a boost compensated/aneroided fuel pump. You can't ever get your fuel right with a turbo on an N/A pump. You'll also get more power, easier starting and lower EGT's with a timing advance, as they're set pretty retarded from factory. If you do that before you intercool it, you'll then be able to monkey tune it like you just did with your EGT's when you eventually get one.

Up the boost to 12psi and turn the fuel 1\6 more of a turn. Not going to get hot if you have the boost to burn the fuel. Awesome vid as always.

Great result👍
a small top mount will be 150 bucks on ebay, as long as its welded youll be sweet. itll give you way more power and let u wind some boost through it
Sick exit point on the exhaust
Hey guys love the build, would make much difference if had the stock intercooler n scoop?? Don't now much about turbo set-up
Sounds great 👍
I would have gone for boost lower down the Rev range to improve power off road, but a great vid none the less😎👍👍
Dont be afraid to put more boost in, more boost will keep the egts down, try and create the least restriction points leading to intake
yeah boys love the patrol
Needs a front mount. You will be shocked how good it goes. Good video 😎👍
With that hill climb, your definitely doing well considering you have a big steel canopy on the back now!?! Big improvements
Wishing the pub was open great food there!
Change cross over pipe to round & lift the lid on your intake manifold makes massive difference

idea for the next one: is a staino snorkel better/more efficient than plastic? (like the one's running now)
you should get a fairline fibreglass bonet scoop
490 egt are pre high, Defs add a intercooler and some more fuel and boost.
