What is the difference between the GTX3576R and the GTX3076R Gen II?

The turbine side. Both use a 58mm compressor rated to 750 horsepower, but the GTX3576R Gen II has a 68mm turbine wheel and GT35R housings against the 60mm turbine of the GTX3076R. Garrett therefore lists it for engines from 2.0L to 4.5L, while the GTX3076R covers 1.8L to 3.0L.

What comes with the GTX3576R Gen II Assembly Kit?

The GTX3576R Gen II Assembly Kit includes the 851154-5003S super core with compressor housing, the 740902-0032 GT35R turbine housing kit in 0.83 A/R, and a gasket kit. The core and housing ship as separate boxes, and the owner assembles them into a complete turbocharger.

Is the 0.83 A/R the right housing for my engine?

It is the middle of the three V-band sizes Garrett lists for this core, between 0.61 and 1.01 A/R. It suits most engines from about 2.5L to 3.5L that want a balance of spool and top-end flow. Very large or very high-rpm engines may prefer the 1.01 A/R.

How fast can the GTX3576R Gen II spin?

Garrett sets a maximum allowable speed of 145,000 rpm and states that operating above it can cause damage and premature failure. The compressor housing has a factory-machined, plugged speed sensor port that accepts the Garrett GT and GTX sensor, sold separately, so shaft speed can be logged.

Do I need an external wastegate?

Yes. Every GT35R housing Garrett lists for this core is free float, and this 0.83 A/R version has no internal wastegate. The exhaust manifold needs a V-band turbine flange and an external wastegate to control boost. A V-band downpipe completes the hot side.

Description

Garrett GTX3576R Gen II Assembly Kit, 0.83 A/R V-Band Free Float

Garrett’s GTX3576R Gen II Assembly Kit puts the 58mm compressor of the GTX3076R on a bigger 68mm turbine wheel and GT35R exhaust housing, which moves the target from small four-cylinders to engines of 2.0L to 4.5L. This version pairs super core 851154-5003S with the 0.83 A/R V-band free-float housing, kit 740902-0032. Garrett rates the GTX3576R Gen II at 400 to 750 horsepower. The larger turbine suits a 3.0L six or a bigger engine whose exhaust flow would crowd a GTX30 turbine, run with an external wastegate. On a 2.0L engine the GTX3076R is usually the more responsive choice.

Features

Gen II compressor wheel with a 58mm inducer, which Garrett says supports up to 20 percent more horsepower than Gen I
Fully machined speed sensor port, plugged from the factory and opened with a 5mm Allen key
0.83 A/R free-float housing with V-band joints at both ends, clockable to the manifold and downpipe

Specifications

Garrett turbo reference: 5862
Compressor inducer and exducer: 58mm and 76mm
Turbine inducer and exducer: 68mm and 62mm
Turbine housing: 0.83 A/R, V-band inlet and V-band outlet
Wastegate: External (free float)
Bearing system: 8mm dual ceramic ball bearing
Maximum turbocharger speed: 145,000 rpm
Rotation: Standard

What’s Included

GTX3576R Gen II super core 851154-5003S with compressor housing
GT35R turbine housing kit 740902-0032, 0.83 A/R, V-band inlet and V-band outlet
Gasket kit

Applications

The GTX3576R Gen II Assembly Kit is not vehicle specific. Garrett sizes it by engine and output:

Engine displacement: 2.0L to 4.5L
Power range: 400 to 750 horsepower (Garrett rating)
Manifold requirement: V-band turbine flange with an external wastegate

Notes

Ships as an assembly kit: super core and turbine housing kit in separate boxes, bolted together by the installer
An external wastegate is required, because this turbine housing has no internal wastegate
The GT and GTX version of the Garrett speed sensor kit is sold separately
Garrett states that running above 145,000 rpm is at the owner’s risk and can cause damage and premature failure
More housing sizes for this core are in the GTX3576R Gen II range

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
