so...what do you think???
I think these should've left the factory like that, it's a giant kiling engine that td5, with one of these on it

BAS VNT Installed
This evening I have finished the installation of my VNT from BAS. Took an hour to remove the standard turbo and about 6-7 hours to fit the VNT after that (first time for me working on the TD5 turbo)...
(note: I haven't bolted down the heat shield yet in the picture - Pete tells me he doesn't run the heat shield on his own vehicle, but it fits and I intend to run with it)
Just took it for the first drive:
Peak pressure of 24psi - thats with my TD5 Alive/Alive Tuning/Serk Motorsports Intercooler.
Average pressure when driving is between 15 to 22psi.
Amazing how sensitive the throttle is now. Pulls hard from low with very little push on the accelerator pedal. I'm a happy customer.
Removed the waste gate solenoid actuator from the vehicle. The boost pressure hose goes directly from the intercooler pipe to the waste gate on the VNT. I have run some blue 6mm silicone hose for this which is joined to the original 4mm black hose.
The installation included removing the exhaust manifold, air intake pipe, the original turbo (obviously), the turbo oil feed and drain lines, the centrifugal oil filter housing, the spin on oil filter, front and mid crossmember bars and the front exhaust dump pipe. Ended up being a bit more than I expected as it was very quick and easy to remove the standard turbo.

Any chance of a test drive in Melbourne???
Awesome work

Definate improvement, but my tune is way out. Running far too rich at WOT - thick black smoke line out the back of the truck. I find that I have as much power at 1/2 to 3/4 thorttle as I do at WOT. TD5Inside are going to adjust it for me, hopefully that may help.
It makes it feel like a more modern engine. I am looking forward to fitting my Ashcroft TC next - got it sitting in the garage still - I just don't look forward to dropping the gearbox...I think these should've left the factory like that, it's a giant kiling engine that td5, with one of these on it
Hello,
I have had the same VNT on mine for about a year now have had a re-map from TD5 inside and WOW they are very good at what they do. You will be very happy with map.file. I am running windows 7 and found that I had to download the file straight to the SD card as if I put it to a file on my hard drive it would not load into the car ECU at all. Maybe just my computer ???
I did the air box mod today and even better pulls a little lower rpm , now ready for the 3inch exhaust next week.
Even with the boost box I still get to limp mode under very hard driving I watch the boost gauge to about 20psi looking at enlarging the actuator pipe to about 12mm so it get more pressure sooner. I have noticed through that it does more when I have the LPG running when off it does't do it so much.

SupporterI'm on an Apple Mac. Hopefully I won't have too much drama with it.
What is the air box mod that you have done?
Why 3"? from what I have seen, the turbo itself is the biggest restriction and choke point in the exhaust system. There's a few UK tuners running some seriously high boost TD5's with still on 2.5" exhaust as they found no benefit in an increase in size.
I'm not saying their isn't a benefit, rather I'm curious if you have found any such information.
AFAIK the boost box tricks the ECU with regards to the MAP sensor reading - i.e. in reading what the pressure level is in the inlet manifold.
But have you done anything to trick the MAF sensor? As this sensor when overloaded (caused by too much air flowing through it) can cause the vehicle to spit it. This is a problem I have on my rig when I first purchased it. Three solutions that I know of:
1. IRBDevelopments two channel booster box (however, IRB Developments do not seem to respond to e-mails and their online store is down)
2. uprated MAF sensor from Alive Tuning (formelly TD5 Alive - this is the option that I run, the MAF sensor is of cheap replica quality, but it solves the issue)
3. bypass hose around the MAF sensor - so from the airfilter box to the air intake tube prior to the turbo. This is the option that Pete from BAS recomended to me. Size recomended was 19mm.
Hello,
here is the link

This made quite bit of difference to pick up and when she gets going even better pulls great.
The boost box is from TD5 Alive stops the ecu seeing the over boost but still cuts out at around 22+ psi it shouldn't but a couple of others I know do this but easy to reset the fault codes on the fly as I set up knowing it will trip and when it does reset straight away do not even stop.
As for the MAF I have siemans MAF and a Diesel Tuning MAFAM which boost signal under 3000 rpm and then once past that point it is normal signal then limits it to 4.5volt, also have done the MAF bypass.
As for the 3 inch with the 7 degree cone then 3 inch it will spool even quicker (nice tone) if not better re-install the 2.5 inch.
Hopefully I can finish off my inter-cooler been taking a long time but very busy. Only have to seal the ends and put it on, have the radiator ready and mounts welded on only have to fit it up. putting the water pump is a bit of a problem as the pump is a little big. The whole inter-cooler sits where the intake manifold is pipe the turbo up and over the engine.

SupporterCheers. Mine has already been done by the previous owner.
Interesting. I run the Alive Tuning Boost Box and their uprated MAF, I have absolutely no issues now with cutting out and limiters. Prior to installing their MAF I did have issues with the limiter.
Very keen to see this setup!

Hi, I have just fitted The VNT last night and I have some Serious smoking issues as well as oil dribbling out of the exhaust.
Has anyone else experienced this at all? I did not have any issues with oil or smoke before I changed turbos.
I plucked the turbo this afternoon after I took it for a run to see if it was just some residue but with the oil dribbling out of the exhaust I was more than a little concerned.
After examining the turbo I found no "wet" internal surfaces.
I think I will fit the standard turbo again just to do a comparison and be sure there is nothing else that has decided to play up.
Cheers

Hello,
Just a quick one do you still have your EGR still on the car?? Also if you have done the MAF bypass, have you still got the engine breather going into the intake pipe?
You could take the outlet pipe off the turbo and get some to give it a little rev hold you hand at the outlet of the turbo and see if there is any oil on your hand reconnect it and do the same at the manifold and this will give you a better idea where your oil is coming from. Or you intercooler is fill of oil and needs a clean
