AGP-OCC

The Caliber SRT-4 being a high horsepower turbocharged car runs a significant amount of piston-to-wall clearance. The cylinder pressure from the forced air creates more heat in turbocharged applications when compared to non-turbocharged engines, thus DCX designed a "loose" engine for added safety and longevity purposes. Unfortunately, a byproduct of an engine that allows a lot of blow-by is oil residue makes its way past the PCV system and ends up in the intake manifold, and many other places.  

Oil residue in the combustion chamber of an engine is bad news, and can lead to really bad news with respect to how your engine runs. We have been selling a real solution for a while now that will actually separate the oil from the air flowing between the PCV and intake manifold. It sounds easy enough, as many people have tried to adapt simple catch cans and industrial water valves to remove the oil from the air. Those products do work OK but only separate a small amount with respect to how much oil is actually passing through the system. Enter the AGP Oil Accumulator.  

Our three chamber oil separator gathers the airborn oil particles through the middle chamber. Oil is separated from the air through the filtering media and drains through a perferated aluminum plate on the bottom side of the middle chamber then accumulating in the bottom chamber. As this oil gets filtered through the middle chamber, clean air is then filtered again and exits through the top chamber. This three chamber system design provides the best protection against unwanted oil making its way to the combustion process.  

The bottom of the Oil Accumulator has a threaded 1/4" NPT bung and a plug to allow the user an easy way to drain the oil.  

The Oil Accumulator is completely constructed of aluminum and is highly polished to provide some extra 'bling' to your engine bay. This will fit the SRT-4 perfectly and comes with hose and hose clamps for an easy installation.

Ditch your stock Caliber SRT-4 wastegate actuator for a high pressure adjustable AGP billet aluminum unit. This replaces the factory installed piece, and will allow you to hold higher boost pressures to redline.  
Because the AGP Wastegate Actuator has a higher base spring rate, it allows the turbo to push higher, more stable boost. This actuator will help eliminate the boost oscillation that is caused by the stock weak actuator. Additionally, all AGP wastegate actuators are easily adjustable. You don't need to remove the actual rod end from the turbo in order to adjust preload (like you do on other brands). All you need to do is loosen the jamb nut, then turn the entire rod with the adjustment nut. It's very simple.  

For cars with an aftermarket piggyback system, or the newly released Mopar Stage 1, this is a necessity for you. For those who are still running the factory PCM and fuel system, this can still work for you in flattening out your boost curve.  

Included in the WGA is the 8psi spring, and we also include a 19psi spring for those wanting to crank up the boost to the moon.

Each RTS2B turbo receives a standard rebuild in addition to the billet compressor wheel upgrade and obviously fully balanced.

RTS3 Turbo
RTS3 Turbo
Our Price: $935.00

Ladies and gents, I present you with the RTS3 Caliber SRT4 turbo upgrade. This product is the evolution of our infamous RTS2B turbo that has rocked the Caliber scene since the release of the Caliber.

- Similar to the the S2 wheel design [which is nearly 6 years old] with much improved aero.
- Larger and yet LIGHTER comp wheel to take advantage of the upgraded turbine wheel
- Includes the upgraded turbine wheel also (so yes, both the comp and turbine wheels are upgraded over stock)
- On paper it should be capable of 25-30whp more MAXED out over the RTS2b without any loss of spool due to the increased efficiency. It wouldn't surprise me to see a bit more than that if someone pushed it hard enough
- Proven by the worlds 2nd quickest Caliber SRT4 at 11.3 in the quarter mile on a stock motor!
- Pushed hard enough, this turbo can certainly get you into the 10 second 1/4 mile range with a built motor

Please see attached comparison pic of the RTS2 turbo vs RTS3 turbo as well as a few other S3 pics.


** PLEASE NOTE, each turbo is built to order and can take 2-4 weeks to ship**
