Turbo Upgrades for the GUIV TD42Ti

[MudRunnerTD]

OK Guys, I am in the market for a Turbo for the GU and keen to hear what everyone thinks will work for me.

So I'm keen to find a little more power. Control the heat and EGTs and give me good power for towing the camper.

Options I am seriously considering include

• Cross Country Ultimate intercooler
• Mamba 18g 6cm I think?
• UFI 18g 6cm I think?
• Borg Warner something???
• Swapping diff ratios to 4.3s from 3.9s ( anyone have any they want to sell?)
• Hi flow injectors
• Inline pump.

Is 18g X 6cm the right setup? I understand it will boost fairly early so good for towing.

I'm keen Not to upgrade the pump. I might need a clutch though?

Hoping to see somewhere around 140 to 160 rwkw. Currently pushing about 95rwkw

Cheers guys

Thanks Kimbo. You should get good coin for the 4.6s mate, everyone wants them.

I heard those BorgWarner 6758's are ideal and might be just what you're chasing old mate

Oh alright then.

Very easy for the turbo mate. Borg Warner EFR6758 with T25 0.64 A/R turbine housing. Im not a fan of top mounts but that is up to you and it will do the job at your desired power levels. Dont bother with the cheap junk.

If you are going to stick with your current tyre size I would only go to 4.11 ratios. This will also make your search a lot easier as they are a dime a dozen. 4.3 ratios are hard to come by.

No such thing as "Hi Flow" injectors. The injectors will deliver what they pump puts out. I would just get yours reco or exchanged and set to standard pressures. A lift pump is also highly recommended and I will give you the same recommendation as winnie, Carter 4600 or 4601.

The clutch should be ok for your desired power levels which you may have to lower your expecatations a little. I think you will be lucky to see 130rwkw. 160 is out of the question

Thanks Matty, some dude sent me a pm said nearlly exactly the same thing so I reckon your onto something mate.

I'm Pretty keen on the 4.3 ratios and I might have found some. The inline pump was the 4601 as you discussed in Winnie's Thread for sure.

So the hiflow injectors I thought would have an increased CC input flow and would be advantageous? I understand though if the pump is not asking for the flow then it's pointless.

My Clutch is the original clutch and has 265k on it and I assume it's at end of life but will only change it when it tells me it's knackered.

Given I am not looking for big KWs is the Mamba really that bad an idea? There is a bit of cash involved so a massive saving there is attractive. What is the BW likely to cost me? Pm if you like. Can you help me source this? Given the UFI are well regarded is this worth considering and $ for $ will it be as good as the BW?

@Winnie I'm pretty keen to stay with a Top Mount as I already have a hole in the bonnet so a bigger hole will work for me. I reckon the Fairline scoops look Sik too. But if there is big coin to save then I could be convinced that a Front mount will work and leave the scoop there for Ventilation.

@Hodge do you have a bigger Turbo on yours mate?

I dont know who is giving you this "Hi Flow" Injector idea but let it go. The pump determines the CC's delivered not the injectors. The injectors are just a valve really that is set to open at a given pressure that is all.

Yeah you will just have to see with the clutch. It might be alright but then it may also slip. Some standard clutches seem to hang on fairly well others dont.

Forget the cheap junk mate, dont even bother. I dont chase big kws either only torque and this where the Borg warner really shines. Andy could tell you nearly exact costings but it will be 2500-3000 likely. The ufi is a good product but it should be. The Borg Warner is loaded with features that none of the others in your list even come close to. You only have to look at Andys last tune where he was only producing 160rwkw but a massive 784nm. Show me other setups with those sorts of figures? The vast majority with that amount of torque will be hovering around the 200rwkw mark. The Borg Warner is aiding the results a lot as it responds super fast but also has the volume to boot. this means we can burn all the fuel being thrown in early and create a nice torque rise and curve. It is the way I would be going.
