I'd be very interested in the results of trying a GT30 on Marin's duesel, make sure you let me know.

Not sure that is going to happen quite the timeframe described earlier, I've been spending, and will be spending money on getting the truck offroad-able (to my standards) and then actually driving it a bit.

The upcoming navrun will be my trucks first outing doing some real driving, so will be able to get an idea of how it all performs in the real offroad world (although I have heard the offroading may not be that hard....). Am also hoping to have my modified injector pump on for that, but still the same turbo. Amount of boost is not decided yet, will see once the pump in on how much boost we can get out of this turbo (remembering I would actually like to sell this turbo once I get another 1!).

But it is still on the horizon.....

Testing at Dzltec's 9:30am Tomorrow

Pre and Post Power



Pre and post Torque




We are flat lining intake temps as usual and minimal pressure drop, just waiting for Dzltec to sort the graphs out, they will not be too different to Marin's. The triple pass heat exchanger brought temps down a little but not quite as much as I expected. Some food for thought there. But on the whole a good result and the owner is very happy with the new found power.

AFR's are good and very little black smoke, EGT's are lower too.


On 33's and AUTO and a stock fuel pump oh yes and a 3" exhaust.

Do you have boost pressure and egt graph, type of turbo and any pump mods etc?

Yes we do I'm just waiting on Dzltec printing them out, couple of technical issues with the printer and dyno not talking.

We have pre and post EGT's

Boost 10-11psi with the Turbo from the DTS kit (Mitsubishi I believe)

All in all pretty much the same results as Marin's The bolt on is just as effective at these power level.

Pump is stock.

What can i say but very happy. EGT's are lower, power and torque is up a lot, the car drives very differently. On hills where it used to run out of puff in overdrive and lose speed it now accelerates! People need to remember it's a standard GQ pump with a standard DTS kit running 10psi and 33's. The difference is awesome.

errrrr you got fark loads more toque than me. Wonder what the go is there?

Its an auto there show torque in a very different way.

What diff ratio does it have?

Stock 4.11's

Busmans dyno runs were also done in a 2-3 gear shift so we can reproduce runs consintently. That torque figure is in 2nd gear, also helping is a torque convertor.

Hey andy... we can always fit yours up to my truck if you wanna see how good it can be saves it sittin in the box

First up is the Pre intercooler dyno run v Post, with no adjustments.

As you can see we picked up about 3kw neither here nor there, but the lower graph shows the AFR's have changes quite a bit with the colder denser air. Pre Blue post Red



The first adjustments brought the AFR's up to around the same.



If you then go back to the above graph with kw and Torque previously posted for the final run, you will notice after the tune 3rd gear holds it power far better and no longer drops off quite so dramatically.

Pre and post map are as expected



Intake temps after the intercooler were a little higher than expected, with the triple passed custom radiator and 10"spal fans but were always heading south on the dyno run's as they shed any heat soak from idling.

Started another small run of 5 intercoolers.

PM if your interested.

Matt, do you think I'll have troubles using a setup like this after the throttle body? Essentially the intercooler box would become my inlet manifold and it is going to be bolted onto the factory inlet runners.
Would I have to place extra internal bracing to prevent the unit collapsing under vacuum.

Lag maybe, when you get on the power you have to more vacuum to fill from the T/B think that makes sense.

The intercooler will be replacing the top half of the inlet manfold, so hopefully the volume increase won't be that much.

If that's the case then I can see too much change other than cold air

Looking great guys!!! Reminds me I need to finish building mine...

so has the GT3082 had a run on the mav yet Marin?

LOL nah, that plan got scrapped.... but am now trying to decide between GT2860RS, GT2871R, GT2876R.... and the GT30 range are still to be thought about.....

Have been out finally getting to drive the thing offroad! EGT's do rise, but nowhere near as quickly as an air to air when sitting and spinning on a greasy hill. Although it is kinda hard to be watching engine temp, EGT, boost and drive up a slippery hill at the same time.

so did youu scrap the idea of the GT3082 coz of time? or dont think it would suit?
Its a lot bigger than the GT28s, I'd be curious to know what you go with

No, it was scraped because matt wanted to use his car lol

Also there is somebody on here with a GU ute that is upgrading his factory turbo to a GT3071R (i think it was) so i'm also going to wait and see what his is like when that is installed. Easy to just go and buy one, but getting feedback on the different turbo's when installed also helps with the decision making process.

What!! tell Matt stiff shit, theres testing to be done

Its definitely good to know someone else has had success with something before handing over a fistfull of moolah.

cheers

My turck is of the road as of Sunday while I servise the front drive line and have a new crown and pinion fitted.

If Marin pulls his finger out he can test my turbo then.


But if he takes it out he puts it back as he found it with no exhaust leaks

do GT28 and GT30 hook up all the same? i.e. inlet flange and exhaust etc etc? is it all the same can just swap them in and out?

Short answer, no. 28 is t25 flange internal wastegate, matts 30 is t3 and external, but it will bolt straight up to your manifold. Inlet and outlet pipes of the compressor housing are off different sizes.

Hi guys, very interested in fitting this to my GU, recently converted the 3L to the 4.2 and looking forward to making some good power. Has any progress been made on fitting the radiators to a GU, i'm not sure what my options are.

Cheers

Just buy one, Hebble, we will MAKE it fit! You could have a party in behind a GU grill, there is that much room!

Haha, love your enthusiasm Ben. Spose i'm just a litle too cautious with the GU. SPose you'll be changing that soon enough HAHA.

Gonna start making up some barwork with Ben soon so we'll get towards better protecting her.

Any way back on topic. Def going to go with this cooler looks and works the part. May even anodize it lol.
