Conclusion from our Test:
Starting off from where we left off on our 2011 STi sedan.
After finishing product testing on the Tomei Arms M7960 it was time to test out another turbo. We chose to go with the brand new state of the art GTX billet wheel technology from Garrett, and use the ATP GTX3076R Stock location turbo.

The goal for this stage of the build was to really maximize and fully utilize the stock components along with having a very fun and efficient car that was realistic for someone to drive on the street, track or drag. This turbo would be the perfect match for anyone who is trying to get the most out of a stock motor, have quick response, and have one wicked car.

To put everything out on the table, we really feel as though we were maximizing several key components on the car, the motor, and clutch is still 100% stock. The Process West intercooler was getting close to its peak efficiency, the turbo was running at 25Psi, and given the octane of fuel we were getting close to the peak stability point of both fuels that where being used. The amazing thing is just how fast this turbo spools, looking at both race and pump gas you can see that compared to the stock VF48 the increase in lag is quite minimal for the huge gain in performance. Also given the altitude of 4200ft this turbo, compared to sea level it would be able to easily produce over 400WHP at similar conditions due to the increased air density.

The power delivery on the vehicle is very smooth and predictable, given the high efficiency TMIC the lag is kept to a minimal and the throttle is very responsive. The vehicle very easy to drive, quick, fun, and overall a simple build utilizing quality bolt on components from proven manufactures ensuring that everything is running at a safe and optimal level.

Huge thanks to the following manufacturers:

Advan RZ-DF in Matte Black!

Advan is at it again with this new wheel that’s for sure to go down in the history books, the Advan RZ-DF in Matte Black. This is the same wheel as the already popular Advan RZ but the DF indicates that this wheel sports the “Deep Face”. So instead of concaving spokes that you would get on the RZ, the RZ-DF will give you a deep dish that will comfortably hold your cell phone, Benjamins, pack of smokes, Domokun doll, water bottle, or whatever your heart desires. That is if you feel the need to let everyone know what you can fit in the lip of your 19” x 10.5” wheel with a +15 offset.

The finish in the picture is a simple, yet elegant, Matte Black. Sure to compliment any color of car, rest assured you will not leave anyone disappointed. Other finishes such as Silver and Bright Chrome are also available. For the size, these wheels are pretty light, weighing roughly 21-22 lbs each which makes them that much sweeter. I don’t know about you but I cannot wait to see these wheels mounted up on someone’s car!

If you are interested in acquiring a set, please contact us at 1-888-45-RALLY.
