Introducing the AGP Stage 4 Package; from this point forward, let it be known as Stage 4. We know what you’re thinking, “Not another confusing turbo kit offering from the turbo guys at AGP!” The reason why we’ve decided to create this package is for the sole purpose of simplifying your upgrade path for your SRT-4.
So you’ve just purchased an SRT-4, you love everything about it: the seats, the looks, the handling, and the power. However, you’re a gear head and can’t leave a car stock, and what better than to increase the performance of the car with, hrm let’s say about 200 more horsepower. Up until now, you’ve had to piece all the parts together to make it all work properly to get over 400whp on pump gas, and it’s been confusing as hell for most of you. Now it’s simple.
The heart of the Stage 4 is centered around the AGP T3T04 Turbo Upgrade Kit. This kit starts off with a new exhaust manifold centered around the Garrett T31 High Flow 4 bolt outlet turbine housing. Turbo placement is a key variable in this design, because of the clearance with the engine and firewall. Rest assured, the centerline placement of the turbocharger allows for enough room so you DO NOT have to “convince” your firewall. NO DENTING OR HACKING OF THE FIREWALL NEEDED with our kit.
The next step is integrating the highest quality and perfectly matched turbo assembly into the mix. As our base turbo, we’ve chosen the 50 trim T04E compressor and a Stage 3 T31 turbine wheel surrounded in the higher flowing newly designed 4 bolt outlet T31 .63 A/R turbine housing manufactured specifically for the highest flowing performance. We add an elbow to the compressor housing so that it will line up to your factory charge pipe with a little modification. The Turbonetics Evolution external wastegate has been the choice among racers in all industries. We needed a way to properly manage the exhaust flow to the turbine as to prevent any unwanted boost creep, but still allow enough control for those wanting to put the engine to its limits.
In order to physically make the turbo kit work properly, the Stage 4 includes the external Blow Off Valve kit with the Turbo XS Type H-RFL and the AGP Cold Air Intake. Since the stock turbo houses the system’s Blow Off Valve, we need to add one into the mix with the kit. For those wishing to replace the cold side Upper Pressure Pipe, we offer the AGP UHP kit as an option with Turbo XS Type H-RFL, Turbonetics Raptor, or HKS Super Sequential. The AGP CAI is available in a variety of colors to match your particular taste.
Get all the fuel system parts you need to support over 400 horsepower on your 2003 and up SRT-4 included in the Stage 4. The system starts out with the Walbro 255lph high pressure fuel pump that feeds the 750cc RC Engineering saturated injectors (high impedence). You’ll need a way to manage that fuel so we include the Turbo XS DTEC with detailed installation and tuning instructions and pretuned fuel maps. Wire it all in, adjust the fuel settings, and you’re set. Fine tune the system from there!
Next on the list in the Stage 4 is the Turboneitcs Variable Billet Boost Controller to fine tune your boost curve.
A key ingredient in achieving the 400whp on pump gas number with Stage 4 is upgrading the the factory intercooler with one of AGP finest products, the Direct Fit FMIC. You do not have to remove your factory “crash bar” with this intercooler. Do not let it’s size fool you, this bar and plate core packs a huge punch in allowing consistent air flow at 30-50 degrees cooler over the factory unit. You have the option to choose our Standard FMIC or Race FMIC at an additional cost.
You’ll need to be able to get all this new power to the ground safely. The factory engine mounts for the SRT-4 are inadequate for even a stock car. The AGP Solid Mount kit will eliminate your wheel hop and allow you new found power . This kit is absolutely necessary for a modified SRT-4, and can improve drivability and will definitely cut down your quarter mile times. The kit includes a solid upper mount, solid lower mount, and washers for the top and bottom mounts. Available in black and silver powdercoated finish.
