The factory TD04LR-15GK-6cm turbocharger is...well, let's just say it gives us the opportunity to improve the turbocharger design for the 2003 and up SRT-4. The integrated manifold and turbine housing design, along with the reversed rotating blades, does not lend an easy turbo upgrade path. We can upgrade the stock compressor wheel to a reverse rotation 16G and machine the compressor housing to fit the larger wheel. However, with an upgraded compressor wheel the exhaust manifold pressure to intake manifold pressure ratio soars past 4:1. Modifying the TD04L turbine wheel (clipping) brings the ratio down closer to 3:1, however you are reducing turbine efficiency, and a 3:1 backpressure ratio reduces the engine's volumetric efficiency tremendously. Let the 2.4 breathe!

Fast-forward to today. We have developed a complete replacement manifold, turbocharger, external wastegate, and O2 housing kit that will allow for endless possibilities. Whether you are into drag racing, road racing, autocross, or stoplight-to-stoplight performance, we can build a setup custom tailored to your needs.

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.
