Re: More Power out of gu 2001 turbo diesel
Whats your budget?
What do you use the truck for?
Towing?
Weekender?
Comp truck?
Daily work horse?
Daily Driver?
Tourer?
What do you want, power or torque?
You could go 4.6's and make a large difference before going anywhere else.

If you go 4.6's it will be worse on 35's!! Wrong ratio.bogged wrote:Whats your budget?

Yea?? Care to explain that.turbo gu wrote:If you go 4.6's it will be worse on 35's!! Wrong ratio.
He has 4.3 now, and lowering it to 4.6 will bring it closer to factory. How will that make it worse of a slug on hills??

it will rev harder and be no faster!bogged wrote:Yea?? Care to explain that.turbo gu wrote:If you go 4.6's it will be worse on 35's!! Wrong ratio.

I have a GU 4.2td wagon on 35's and it had 4.6 and i went back to 4.3s and its a far better car with 4.3's as it sits in the middle of the power band not right at the end of it in most situations!
I towed with both ratios carrying the same load and the 4.3 got better economy and faster speeds and could hold gears better!
long steep hill 4.6s you were constantly 2nd/3rd were the 4.3s could hold 3rd all the way on the same hill.
The utes are identical to a wagon in everyway apart from diff ratio 3.9 compared to 4.1. but are 400kgs or more lighter.

Re: More Power out of gu 2001 turbo diesel
interesting. Goes against the 29038023984032984 other threads on it.. specially revs harder and goes no faster. that alone doesnt make sense to me but thats not unusual... Just mine revs harder, and goes faster. Most cars I've driven do..turbo gu wrote:it will rev harder and be no faster!bogged wrote:Yea??

Glad it works for ya anyway.
Re: More Power out of gu 2001 turbo diesel
No point reving the tits out of something if its not making power If your motor only makes power to around 3000rpm reving it to 4000rpm is pointless as the motor has dropped off its torque/power curve!!!!bogged wrote:interesting.

intercooled mine with just a factory intercooler, and wound boost to 14.5 and more fuel handles it fine, but now want more out of it. if you wanna go much more than 15psi you'll prob wanna look at a bigger fuel pump, because the standard pumps tend to run out of fuel after about 15 psi.

I wouldnt bother with the Highflow,bobbyjane wrote:i use the car for long trips there is no real budget i just want to obtain more power with out overheating
i have spoke to a couple of people and they reckon toe high flow the turbo has any once done this and was there a difference
Sell your old turbo and bolt on a roller bearing turbo setup do that as it will flow more air so you can put more fuel in and get more power hence exhaust temps shouldnt be an issues.
If your having engine temp issues, check your radiator, thermostat as that will affect it also.

yeah its thats better option however you may get $600 for your turbo, a new roller around 1500 or less including adaption plate..bobbyjane wrote:i spoke to a guy at mtq turbos he advised me to do a high flow turbo
but what they do is cahnge the standard inpellor which is just a bush bearing to a ball bearing one and then they port out the housing
he reckons a increse of power by 30 percent
Personally i would get a new turbo, all fresh no stress on the housing...
but..
your choice... hope this helps, if you put the right roller on expect about 130 rwkw fuel pump maxed out....

it all comes down to budget.
You can spend $600 to $20,000
