Description

The Garrett GTX Ball Bearing GTX35R (aka GTX3576R 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 GTX3576R 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 GTX3576R 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 GTX3576R 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.

    Answer

    Is it cabable to make 500whp with id 1050x cc injectors or it need bigger injectors ?


    • A: You will need to consult your tuner for specific set ups. More than likely you will need bigger injectors.

  • Q: 07 WRX STI 2.0L BCR stage 3 Cams will this suit.  Ryan64 1 month ago

    Answer

    Hi Im in New Zealand and have a 2.0L twin scroll VF49 and have just had Brian Crower crank, Rods and JE pistons plus have had head ported with oversized titanium values and stage 3 cams installed now looking for a bolt on turbo and intake manifold to suit would this be the way to go? As it will be raced the only regulation is I have to use stock exhaust manifold. So was thinking this ATP GTX3576R and the Cosworth intake manifold.


    • A: This turbo is a single scroll turbo and would require more to be changed on your current twin scroll setup including the manifold, uppipe and possibly the downpipe. Because you need to keep your factory twin scroll exhaust manifold, this is not doing to be a good turbo option.

  • Q: iwg or ewg  omar 1 year ago

    Answer

    is it possible to convert this type of turbo from iwg to ewg??


    • A: You can get a universal bracket that is designed to keep the internal wastegate closed. And then you are going to need an external waste gate and up pipe that is designed for an external waste gate.

  • Q: fitment  tahn87 3 years ago

    Answer

    According to Ian who posted a 2 star review it has bad fitment, can RSD or anyone from ATP confirm the fitment on 2011 sti? I do have intake phonetic spacer from cosworth if that makes any difference. Also, if an adjustment or modification is required to be made what would it be?


    • A: Any 3 inlet turbocharger is very tight and difficult to fit underneath the intake manifold and the only way to properly avoid this would be to go with a rotated setup. A soft silicone inlet like Perrin's does help make installation a little easier but it can almost always be expected to be a tight fit.

  • Q: Spool rpm?  mr_kris7787550 3 years ago

    Answer

    So I am debating between this turbo and a Blouch Dom 1.5 xtr, but I don't want a monster turbo that does not spool till really late. I am wondering what rpm I could expect this to spool at on a 2005 sti?


    • A: The 1.5XT-R and this 3576R are completely different in power ratings with the 1.5 usually seeing about 350-400whp depending on setup. The 1.5XT-R is likely to spool around 4000-4500rpms, the 3576R can be a whole 300-500rpm+ later depending on setup.
