Thread: VNT turbo is fitted photos

Mmmm. Nice shiney stuff

Do you have boost and EGT gauges fitted? If so, how early does it start to build boost?

Looks like a lot of turbo. Neat setup, looks a lot more accessible than the original setup. is the turbo as close to the washer bottle as it looks? Also interested in the egts and performance.

Yes it close only a few cm to spare the compressor casing almost touches the plug for the washer motor. I wrote and informed them that could be a refinement for future models, I don't see it as a big problem yet. I keep an eye on it and make a small heat shield if required. I'll need to increase the fueling over my adjustments done already, when I fitted the APT intercooler. But I'll run o the existing settings for a week or so. I monitor the EGTs and boost on the trip.

Looks good, It you don't mind me asking where did you get it from and how much did it cost? Thanks

Just wondering which model VNT did you use

VNT is a Garrett 2256V. The kit is from madman in south Africa, the cost at the time was 1800$ plus $300 freight , but that's dependent on the exchange rate.

I've just done a 650 km round trip to chinchilla to visit friends. Via Toowoomba and Dalbly so there was some good hills to try out the new turbo. My observations so far are.
The dead band low down in the rev range is gone, I have a boost almost from idle and the power build up is seamless. It's never going to be TD-5 or a V8, but it's a definite improvement.

The power for hill climbing at highway speeds is much improved I can hold 100km/hr up most of the hills in top gear simply by putting my foot down. Earlier my foot would be flat to the floor. and the EGTs would be climbing rapidly, engine temp going up, and the engine would be slowing down and falling off the torque curve.

The EGTs are about 50 deg lower than usual.and I have 3 or 4 PSI more boost all the way through the rev rang, and that pressure is now measured at the manifold not the turbo charger outlet. The increase in boost pressure is probably caused by the increased efficiency of the more modern turbocharger. The engine is running cooler, water temperatures stay at about about 82 deg even on long climbs, oil pressure is holding over 3 bar, a sign the oil is staying cooler.

My impression is a good improvement in drivability, I expect it will be very noticeable off road or in the sand etc.

My fuel pump had some minor tuning after I fitted the APT intercooler, (stop screw and diaphragm only) but none since I fitted the turbo, so I'm thinking some increase in the fuel pump settings will need to be done to get the best out of the new turbo. I'v not seen any EGTs over about 580 deg even on very long climbs.

How is the vnt controlled? (Opening and closing of the vanes)

The Allisport VNT turbos are $1850 landed.
Any reason you chose this turbo?

I want to do the same and want to consider all options.
