Actual product varies from the above image. |
AGP's SRT-4 turbo kit starts off with a new cast 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 AGP's turbocharger gives the turbo clearance around the SRT-4's firewall. |
| AGP's turbine side features a GT31 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. AGP does not use the decades-old OEM designed 5 bolt turbine housing due to its flow restrictions at high pressure ratios. |
AGP also added an elbow to the compressor housing so that it will line up to your factory SRT-4 intercooler charge pipe with some modification. AGP's SRT-4 turbo kit uses the Turbonetics Evolution external wastegate to properly manage the exhaust flow to the turbine and prevent any unwanted boost creep, while still allowing enough control for those wanting to push the engine to its limits. The Evolution gate does this perfectly with a few different spring rates (all spring rates included in the kit). The AGP SRT-4 turbo kit vents the external wastegate to the atmosphere to keep turbine efficiency the highest as possible.

Turbocharger Selection:
STANDARD 50 TRIM: The 50 trim is the best matched turbo for the SRT-4's 2.4L motor for street/strip purposes. AGP's 50 Trim SRT4 turbo kit spools fast, and makes great power. The 50 trim turbo is perfect for those wanting to make big power on pump gas and go to the track once in a while at run some 11's. If you plan to run nothing but pump gas, and want the best street turbo for your SRT-4, then the AGP 50 trim is your turbo. Full boost should be right around 3200-3300rpms with a .63 A/R turbine housing. AGP's test cars have pulled over 420whp on pump gas at 23psi. The maximum boost is around 30psi where AGP has seen 500whp. This turbo is not ball-bearing.
BALL-BEARING 50 TRIM: The AGP ball bearing 50 trim turbo kit has the same power capacity as the 50 trim turbo listed above, but has faster spool. Ceramic ball bearings create less friction for faster spool and better response. The ball bearing option costs $500 more, but is a much better SRT-4 street turbo, without any downsides. The AGP ball bearing 50 trim turbocharger is oil and water cooled and includes water lines.
60-1 TRIM: AGP's 60-1 SRT-4 turbo kit can make well over 500whp and support 32psi. Full boost is around 3400-3500 in a .63 A/R turbine housing. While the AGP 60-1 is a good race turbo kit, on pump gas is much less efficient than the 50trim. You will need a built motor to truly take advantage of the extra power this turbo will make. At 30psi it will make 40-50hp more than the 50 trim but at 20psi will usually make ~20hp less, so keep this in mind for street SRT-4s. The 60 trim turbo is ony recommended if you have a built motor and care more about race performance than street performance. This turbo is not ball-bearing.
NOTES:
1. The turbo kit pictured is ceramic coated and polished; AGP turbo kits do not come this way.
2. You must upgrade your fuel system with these kits: We reccomend a return line kit, injectors, a fuel pump, & engine management.
3. All turbochargers listed are oil cooled & non-ball bearing except the ball-bearing 50 trim option.
4. Turbos have a 3" inlet, so an aftermarket intake and the proper couplers will be required.
5. TURBO A/R: All turbos are available w/ a .48, .63, or .82 AR. The .48 will have the fastest spool with the least top-end power, the .63 has a good balance between spool time and top-end and is what JSC Speed and AGP recommend for most SRT-4s, the .82 has more lag, but will produce more top-end power.
6. SUPPORTING MODIFICATIONS: The SRT-4's blow-off valve is in the turbo, so you will need an aftermarket upper pressure pipe (like Perrin or ATP) and blow off valve (bov) with these kits. The turbo inlet is 3", so you will need an aftermarket intake as well. We also reccomend a full 3" exhaust and downpipe, and, of course, fuel system modifications and engine management.
7. KIT INCLUDES: T3/T4 manifold, turbocharger, Turbonetics wastegate, dump tube, 2.5" to 3" O2 housing, oil lines, gaskets, nuts and bolts, heatshield, & aluminum overflow bottle.
FITMENT: 2003-2005 Dodge Neon SRT-4.
