Introducing performance out of a package you never thought possible. This clean sheet product is tailored to meet the demands of hard core racing enthusiasts while providing industry leading power capability in a small package.

The G-Series G25-550 and the G25-660 turbochargers are compatible with 1.4L – 3.0L engine displacements and capable of producing up to 550 and 660 horsepower. G Series 25 turbochargers are smaller and outflow all comparable products on the market.

New compressor and turbine aero combined with high temperature resistant materials allowed engineers to push the limits of performance.

A new name designates a new generation of industry leading technology and innovation.

Understanding the Name:G25-550 || G25-660

G designates 81 years of Garrett® heritage.

25 classifies the size of the frame. The remaining 3 digits identify the max horsepower rating of the turbocharger. (ie 550)

Compressor Aero

Forged fully-machined compressor wheel and new aerodynamics increase maximum horsepower output and boost response. The CFD (computational fluid dynamics) engineered compressor wheel increases air flow up to 15% for 60mm and 30% for 67mm with 79-80% efficiency. (Compared to GTX GenII)

Available in standard rotation and reverse rotation options for enthusiasts that want the perfect twin turbo installation or a single reverse rotation turbo for applications with installation restrictions.

Speed Sensor

The compressor housing features a fully machined ported shroud to help reduce compressor surge. A fully machined speed sensor port provides enthusiasts the option to add the new G Series speed sensor to measure turbocharger shaft speed, a key factor in determining ideal operating conditions.

The new speed sensor is easy to install and does not need to be adjusted for length like previous sensors. Simply remove and plug, then insert the speed sensor and tighten the bolt. The new speed sensor is sold separately and is not compatible with GT and GTX sensors due to the new design and sizing.
The addition of an o-ring between the compressor housing and backplate reduces the possibility of boost pressure leakage.

Center Housing

A new one-piece center housing and backplate increase durability and product safety by reducing the number of failure points associated with the turbocharger. The center housing to turbine housing v-band connection allows for 360 degree orientation when installing with Garrett® non-wastegated turbine housings.

Water Jackets

Four large water jacket ports increase cooling capacity and allow enthusiasts to customize water line routing to help improve the installation process. The turbocharger comes with two -6AN water fittings and two plugs.

*Recommended to install waterlines on opposite sides of the housing.

Oil Passage

A single stage oil passage directs pressurized oil to the new oil cavity ensuring proper bearing lubrication at both sides of the cartridge.

Each turbocharger includes (1) -4AN oil restrictor fitting with a 1mm orifice to provide the turbo with the recommended 40psi of oil pressure.

Rotating Group- twin piston rings

A shorter bearing cartridge allows us to incorporate twin piston rings on both sides of the shaft wheel assembly. This will reduce the likeliness of oil leakage at the seals from the center housing to the compressor and or turbine stage.

Turbine Wheel Aero

The turbine wheel features all new aerodynamics to improve flow and boost response. The new turbine wheel is made of Mar-M super alloy and is capable of handling exhaust gas temperatures up to 1050 degrees C.
The new turbine wheel flows 15-20% more than GTX and has peak efficiency of 74%.

Turbine Housings

All G Series Turbine housings are made from stainless steel to provide ultimate durability and temperature resistance up 1050 degrees C.
Internally wastegated housings are compact, efficient, and designed with maximum bypass port size to reduce boost creep and provide better boost control.
Turbine housings are available in a variety of wastegated and non-wastegated, open volute, T25 and Vband configurations so be sure to order the correct part for your application.

Very good product
Size: Medium, Color: (001) Black / Black / Pitch Gray
I purchased these to wear inside lowcut slip on casual shoes, I don't particularly like to not wear socks in my shoes for hygienic reasons. Prior to purchasing these socks, all I could find were those made of very light beige hosiery type material , and my slip on shoes would slide around a bit. These are light weight and breathable athletic type material, with a very good gripper strip at the heel. One pair of my slip on casual shoes have a particularly lower cut in the toe area, but the shoe is black and I chose the black color and though I see a hint of the sock there, it matches and does not detract from the look of the casual solid black shoe

They stay out! No more sock wads!
Size: Medium, Color: (100) White / White / Mod Gray
Best no show socks ever made!!!!! I've been struggling for 2 years to find ones that actually stay on your foot, even other national brands, and I just became content wearing my sneakers without socks. They ALWAYS slid down into my show & I ended up walking on a wad of sock until I could fix it...or usually just took them off after a couple of tries. Enter Under Armor!!! They a mid weight, but not very thick & still breathable. They work too by actually staying on your foot! Not once have they slid down into my show!! Very comfortable but they could be a little more affordable.

Love!
Size: Large, Color: (100) White / White / Mod Gray
Ive tried so many no show socks but I love these. This is the 3rd set I've bought. They never slip off and the material is thin and breathable. Perfect for working out.

True no-show socks that don’t slide down!
Size: Medium, Color: (100) White / White / Mod Gray, Size: Medium, Color: (100) White / White / Mod Gray
This is the first pair of no-show socks I’ve tried that actually don’t slide down into my shoes. Trust me… I have tried lots of different pairs and this is the one! They fit perfectly. They’re not too thick and they’re obviously durable because I wash them after each wear, so daily.

Great fit but expensive
Size: Medium, Color: (252) Blush Beige / White / Castlerock
These are really great socks. I love them, but they are definitely pricey.
