I have a DTS turbo in my 105 3 inch exhaust it’s it’s 100% better on power and towing got it done at Berrima diesel plus they tuned it and mine is manual

I run this exact combo and have been trying to get sensible responses out of the internet as to what I can do to fix all its limitations without dropping 25k on an FTE. Can’t wait to see what comes next.

Hopefully I can give you some honest common sense options without dropping $30k on an engine swap 😂

Awesome. Just stumbled upon your channel. Really helpful vid. I thought I had the only auto 1HZ 105 in Australia 😅. All jokes aside… I’ve been talking about putting a turbo into for years and now I’m at the point of properly looking into it over the next 18months. Keen to see more of your vids.

Thanks mate, hope I can help you with your decision making! I reckon the auto 1hz is a great combo no matter what people say. I have done a few videos now on turbo selection, inter cooling and other handy mods make sure you check them out! I’m getting it tuned next so hopefully that’ll have it in the sweet spot

Great video, thanks. Keen to see performance with the new turbo, then with intercooler to see the difference that makes and what boost you go up to.

Thanks mate, I’m very excited to run it back to back with each kid to see what really helps if anything 👍🏼

@petermenzel5943 8 ай бұрын

The egts are increasing when you put it in overdrive because the revs are lower and gives the fuel more time to burn in the cylinder whilst also loading the engine up, not because of low boost. the more boost you feed it, the more your egts will increase, same goes for increasing the fuel delivery.

@onstreetgarage 8 ай бұрын

That mostly makes sense to me mate, appreciate that. Only thing I thought was that adding more boost would decrease egt (within reason)

@petermenzel5943 8 ай бұрын

@@onstreetgarage from factory even by adding boost to an na engine will increase egts because you are getting a more complete burn. only time you will get lower egts from adding is boost is by adding an intercooler because you are feeding it cooler/denser air.

@user-qd1bj3qy8i 9 ай бұрын

EGTs only part of what’s going on. What about coolant temperature? That would be interesting particularly with changing viscous hub and fan. Will be keeping an eye out for the next video. Well done!

@onstreetgarage 9 ай бұрын

Thanks mate, I actually have a sensor for the gauge for water temps just haven’t decided how I’m going to hook it up yet. Might have a look how simple it is and get it in sooner rather than later.

I would say its badly in need of a good tune, valve clearance, new injectors and decent dyno tune would get thqt thing going as it should. My na 80 went from.120 to 80 on your last hill on its final trip before getting a turbo so i thought your effort was pretty respectable. Over heating in the 1hz, first thing to check and also the cheapest is the thermostat. Then the viscous fan then the radiator if its old or corroded. Also if everything che ks out and it still does it check injectors and fueling. Will be interesting to see your results. Cheers

@onstreetgarage 6 ай бұрын

These are all great tips thanks mate! I have done the following since this video: Valve clearances New injectors New viscous fan New thermostat Front mount intercooler It’s running 100x better, I’ve got a couple of videos since this one showing improvements and will have results of the front mount this Thursday. It’s just in the queue now for a tune to hopefully bring it all together. There’s also a potential opportunity come up to get an FTE for a great price so just weighing everything up

@SuperSimmo88 9 ай бұрын

The A442F will lock up in 3rd (overdrive off), provided you are not full throttle. I find using the switch to force it out of overdrive, vs. just putting your foot down almost always results in it locking up straight away.

@onstreetgarage 9 ай бұрын

That’s interesting I wasn’t aware it would do that in 3rd also. So do you reckon adding throttle is better than pushing OD?

@SuperSimmo88 9 ай бұрын

@onstreetgarage no, I think doing what your doing is right. It probably comes down to what feels right, and using the gauges to confirm that the engine isn't working as hard. And yes, if you put your foot down enough for it to unlock the torque converter (not a bad thing at all), then it will start to generate heat in the transmission as you say. Perfectly normal, but of course it's dumping that heat into the cooling system, which can put a bit more stress on it if it's not up to the task, but it sounds like you are on to it already.

@Shaanjc96 9 ай бұрын

Keen to see the outcome of this and what changes. Mine is front mount intercooled and EGT’s vary from 280-410° when on the highway but can go to 500° when going up a big hill, sometimes feels like it dies off up the top

@Shaanjc96 9 ай бұрын

That's crazy my 80 series 1hz with a DTS kit and custom front mounted intercooler , I did change out the rear housing to a 6cm tho my egts sit at 230 at 110km then on big hills maybe I hit 280-300 , if I'm towing a car trailer with my falcon on the back I can pull up massive hills on the highway 5th gear for big lengths and the maximum I have seen is around 400° even some hills where I'm holding wide open 4th gear keeping 80-90km I won't go past 400° 430xxx km

I should have mentioned Pump is timed correctly Valve clearance set Injectors healthy Zero blow by I'm hoping to raise the boost up to 15 psi and adjust the AFRs correctly

The more I see of them the more tempted I am to get in one. I had a 1FZ 80 and a 1FZ 105 and they were great cars. I can only imagine how they go with a turbo

@user-lb7xn3do2g 7 ай бұрын

I think one of your main problems might be its not tuned right, these kits are designed to run about 11-12psi I beleive and even during the 0-100 sprint you didnt crack 10psi its probably running quite rich

@onstreetgarage 7 ай бұрын

Yes I agree, tune was meant to happen before Christmas but tuner had a backlog of cars they couldn’t get through on time. As it is I’m very happy with it now with the new turbo so I’m excited it should only get better again with the tune 👍🏼

@ericjohnson6802 9 ай бұрын

Fuel use is up there, much worse than our 250kw all the fruit SC Disco, but better than daughters GU 4.8 which is absolutely terrible. Our GQ shorty and son's all the fruit GU turbo 4.2 EGTs rise rapidly up hills too, despite all the additional cooling fitted and he simply can't tow with it! It'll be interesting to see you're future figures but I expect you'll be seeing similar rapid EGT rises as the power and weight goes up.

@onstreetgarage 9 ай бұрын

Yes I think the consumption is due to the injectors being well overdue for a rebuild as I had a 1hz years ago with a similar setup that was closer to 11-12l/100. In terms of egts I know the 1hz is limited by the flow of the head, I had a 1hdt which never got hot and was much better. You may be right and I see a lot of talk on the internet about what these future mods will or won’t do so I’m just excited to be able to do some real life testing 👍🏼.

@livingstonekot757 4 ай бұрын

Would installing an intercooler, upgrading the engine cooling system including upgrading the oil cooler help reduce the problems associated with turboing the 1hz..??

@onstreetgarage 4 ай бұрын

Intercoolers definitely help. I changed the viscous fan too which also helped water temps a decent amount. I haven’t tried an oil cooler but I reckon that’d be even better again

@ash300186 9 ай бұрын

On the straight and level, a na 1hz will blow straight past 110kph no worries. 10psi at maximum load up those hills is asking for a failure though.

@onstreetgarage 9 ай бұрын

I would say the egt is more of a concern than the boost. And yep a 1hz na is sweet on the flat all day but see ya later in the hills

@ash300186 9 ай бұрын

@@onstreetgarage to be clear, 10psi isn't enough. Trying to improve power using only 10psi will create poor afr and a failure. Especially using such a lazy turbo.

is it worthwhile installing a egt guage for a non-turbo 1hz to monitor temps? If so where would you put it?

@onstreetgarage 5 ай бұрын

I do t think there’s much point. I’m not an expert but the idea of monitoring egts with a turbo as the turbo can push temps high enough to damage pistons. I don’t think an N/A can generate enough heat to do that sort of damage.

@barryprosser162 9 ай бұрын

Identical setup to mine. Auto 1hz dts turbo since new. So keen to follow the upgrades! I assume you’ll have to make some decisions around the trans cooler when you do the front mount? Mine has a cooler already, from factory i thought? Is that the max psi you can get out of your dts? Has your top mount got a fan? Is the bonnet sealed to the intercooler?

@onstreetgarage 9 ай бұрын

Hey mate glad I can help with potential decisions for you. I’ve bought an inter cooler that takes into account the factory trans cooler. When the time comes I’ll consider whether I go to a bigger core intercooler and relocate an aftermarket trans cooler. Im not sure how far you can push the dts unit in terms of boost however no matter how high I push it I don’t think it will address the slow spool up. Top mount is sealed to the bonnet but does not have a fan
