Agency Power released their first EVO turbo kit back in 2004 for the original EVO VIII. This piece was put to the test on big tracks like Willow Springs and Buttonwillow in California, as well as many others HERE in Arizona. We upgraded the original design which used a T3/T4 turbo to Garrett GT turbos and now, Agency Power has completely redesigned the EVO VIII and IX turbo kit. The new GT turbo kit features a redesigned high flow header with a true merged collector. Using all 321 stainless steel and precision TIG welds, the header is designed to maximize your power and improve turbo spool up. Using thick CNC machined flanges, the kit will bolt up without any modifications to the factory radiator assembly. The kit uses either a GT35R or GT30R turbo and a Tial 38mm external wastegate. The kit includes the O2 housing which connects via a band clamp to the supplied high flow 3 inch downpipe. The external wastegate dump pipe bolts to the wastegate and is routed in a safe manner.

To further improve the kit, Agency Power includes a lower intercooler pipe to fit with the factory or aftermarket intercoolers. This intercooler pipe is then finished in a textured black color. We also supply a new turbo suction pipe which features a blow off valve return port. This is also finished in a textured black color. If you are retaining your factory MAF sensor, we include our CNC machined aluminum MAF adapter and K&N high flow cone air filter. The kit then includes all necessary oil and water lines with fittings needed to connect to the factory locations. Finally, we supply Agency Power 5ply silicone couplers and all necessary clamps needed.

As tested on a stock 4G63 motor, we have seen this turbo setup produce more then 550 horsepower and on a built 2.3L or 2.4L engine in excess of 700 horsepower. Corresponding components are necessary to maximize performance. These components would include: ECU Tuning, Larger Injectors, Exhaust, Intercooler, Cams, Spark Plugs, and other related performance items.
