A quick spooling turbo capable of 600 RWHP! The Aurora 4000 is an upgraded turbo charger that is great for added performance on your 24 Valve Dodge 5.9L Cummins. The Titanium 64mm inducer compressor wheel on the turbo is a significant jump in performance over the stock charger. This turbo has the capability to reach 600hp with supporting fuel modifications and higher tuning levels with the ability to run 70+ psi. The increased air volume will utilize all fuel injected into the cylinder creating a more complete and efficient combustion event. This will result in lower EGTs, high horsepower capabilities, and a more efficient/powerful torque curve.
RECOMMENDED ADD-ON PARTS - With the installation of an upgraded turbo, such as this Aurora 4000, we highly recommend also upgrading the exhaust manifold. Besides the simple fact that there is no better time to do so because the turbo will be off, there are many performance advantages, as well. The higher flowing exhaust manifold will assist the turbo to light sooner and provide more boost/air flow throughout the entire RPM range due to a reduction in the factory bottlenecked manifold. And quite simply, the line of ATS turbos are originally designed and tested with one of their Pulse Flow manifolds installed, so you will receive the maximum gain by installing as a package. Also, the multi-piece design provides an area for expansion/contraction to occur, which will nearly eliminate the possibility of a cracked manifold, which leads to a serious performance disadvantage. Finally, this manifold is built with a pre-threaded port making the installation of a pyrometer thermocouple a breeze.

What is the A/R ratio? Also would this be okay on a stock truck with just a tuner ??
You can choose between two a/r ratios for that turbo a .76 and a .85. You would really need to upgrade your fuel system to run that turbo properly, needs more fuel to spool correctly.
Which A/R ratio would I want for a truck with a fueling upgrade and tuner ??
I would probably lean towards the .85 A/R. It will help keep the EGT's down with fueling upgrades and tuning. You might give us a call with your setup and we can get a little closer.
120 over injectors, smarty s03, edge comp box, s&b cold air intake and straight pipe, how would this turbo go with this setup??
Yes this would be a great setup for this application.
Would any exhaust downpipe fit on it or do I need one with it?
It comes with one, uses HX40 flange. SA
How much air/boost does it push in the lower rpms of the motor?
Hard to say for sure, given you may have larger injectors. The ATS 3000 and 4000 tend to light very quickly. If you are running stock injectors and wanting to run the 4000, you may notice a slight delay in low end power, or how fast you can light the turbo. If you are running a little larger injector, perhaps 50-100HP over stock, the 4000 should light VERY quick. -Ben
