Features & Product Details

Just like the GTX3076R kit ATP-SUB-021 but with built in flange for Tial 44mm wastegate on the turbine housing. High flow, less exhaust backpressure, more precise boost control, even more power! Tial 44mm wastegate and dump tube sold separately.

The Garrett GTX Ball Bearing GTX35R (aka GTX3582R aka GTX35/40R), the ultimate 600+ HP capable dual ball bearing turbo, is now available in a drop-in package for the Subaru WRX/STI! The easy to implement turbo assembly that takes no more than 1-2 hours to install in place of the stock journal bearing VFXX unit is made possible by a high flowing GTX inspired ATP exhaust housing and a series of custom engineered components built to suit the installation.

Each GTX drop-in turbo package consists of a Garrett factory assembled and high speed balanced dual ball bearing CHRA which is then assembled into a set of CNC machine ported housings that have been optimized in every aspect for maximum flow and efficiency.

All accompanying oil and coolant supply components included in each kit have been designed to properly and seamlessly bridge the Garrett GTX turbo to the EJ engine so that the fit is as OE as possible.

Just bolt the turbo on, add fueling and a good tune and prepare for a blast of acceleration. Garrett GTX turbos offer more than just "peak HP" numbers. These GTX turbos off more torque area under the curve and more "accessible" power than any other turbos series out there.

We do recommend that you compliment your GTX bolt-on turbo with a nice high flowing bellmouth downpipe and a high flowing inlet pipe to effortless channel air in and out of the turbo. Although every bolt-on GTX turbo ships with a 3" inlet, we do provide a "stepdown" sleeve just in case you're forced to use the stock 2.25" inlet hose. However, as a rule of thumb, turbos, especially higher flowing units love as much inlet flow as possible. This promotes both quicker spoolup and better ultimate HP, with less boost pressure at the manifold. The 3" downpipe and bigger inlet is critical for reaching peak efficiency on the GTX turbo. Please also be aware that some downpipes such as the stock catted downpipe, has a "no-flow" door at the wastegate flapper area. This type of downpipe may not allow the wider swinging wastegate valve to open all the way, thus causing the possibility of a "boost-creep" condition or uncontrollable rise in boost.

The GTX3582R is a great power maker on the 2.5L that still has great spoolup, especially if you're looking for best area under the curve possible, but still need a lot of power in the high revs. The GTX3582R makes boost about 200 to 300 rpms later than the GTX3076R but keeps pumping where the GTX3076R starts to run out after 500HP. A lot of the boost is still available at part to medium throttle. Dual ball bearings means some boost is always there even if you are lugging the engine and boost recovery between gearshifts is awesome with full boost ready even before upshift is complete as the STI lurches forward with shear enthusiasm at the onset of each gear. The 2.0L driver should not rule out the use of the GTX3582R if his HP target is in the same range. This competition grade turbo is still a big favorite for the HP range because it hits like a hammer while other 600HP turbos are still "spooling up".

What sets the GTX apart from the GT series turbo is the new high flowing 11 blade next generation compressor wheel.

2 uppipe gaskets will be needed if using the included spacer.

Not for stock motor 4 years ago
FJG24
So I bought this turbo not thinking so clearly. Kind of got stuck up in the do scripting which makes it sound awesome. Which don't get me wrong it could be awesome. I'm not gonna list every mod I have on my 11 sti. But I would recommend having a built block before going this route. Huge difference between stock and this. Lags all the way till 4300, but does hit like a rocket once spooled. Very hard to get used to. If you auto x I would not recommend this. More for the people that want to go straight fast. I'm very interested in seeing what this turbo has once my block is built
