Who should buy the GTX3582R Gen II Assembly Kit in 1.06 A/R?

Builders with large engines or very high power targets. The 1.06 A/R housing in this GTX3582R Gen II Assembly Kit is the largest T4 option Garrett lists, keeping exhaust backpressure low at high rpm. Smaller engines usually get better response from the 0.82 A/R T4 version.

What does a 1.06 A/R do to boost response?

It delays it. A larger housing slows exhaust gas less on its way to the turbine, so the turbocharger needs more exhaust flow to build boost, while the engine gains breathing room at high rpm. On larger displacement the extra exhaust flow offsets much of that delay.

What is the maximum allowable turbocharger speed?

Garrett lists 130,000 rpm for the GTX3582R Gen II and states that running beyond it is at the risk of the owner and can result in damage and premature failure. A speed sensor in the plugged compressor housing port lets the calibration watch shaft speed directly.

What power range does Garrett publish?

Garrett publishes 450 to 900 horsepower for the GTX3582R Gen II, for engines from 2.0L to 4.5L. Those numbers come from the choke flow of the compressor map and describe potential flywheel horsepower. Fuel, boost, intercooling and tuning decide where a build lands within the range.

Super core 851154-5004S, carrying the compressor housing, turbine housing kit 740902-0016 in 1.06 A/R with an undivided T4 inlet and V-band outlet, and a gasket kit. The core and housing arrive separately for assembly by the owner or installer. It supersedes core 836047-5002S.

Description

Garrett GTX3582R Gen II Assembly Kit, 1.06 A/R T4 Inlet V-Band Outlet

Garrett’s GTX3582R Gen II Assembly Kit in 1.06 A/R with a T4 inlet uses the largest T4-inlet housing Garrett lists for the 66mm GTX35 Gen II core, kit 740902-0016, paired with super core 851154-5004S. It is free float with a V-band outlet and runs with an external wastegate. With Garrett rating the GTX3582R Gen II at 450 to 900 horsepower on 2.0L to 4.5L engines, the 1.06 A/R is for builds near the top of both ranges: a large six, a small V8, or a high-revving engine on a T4 manifold chasing peak power. It is too large for a 2.0L that needs boost low in the rev range.

Features

Gen II compressor wheel with a 66mm 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
1.06 A/R free-float housing with an undivided T4 inlet flange and V-band outlet

Specifications

Garrett turbo reference: 6662
Compressor inducer and exducer: 66mm and 82mm
Turbine inducer and exducer: 68mm and 62mm
Turbine housing: 1.06 A/R, undivided T4 inlet and V-band outlet
Wastegate: External (free float)
Bearing system: Dual ceramic ball bearing, water-cooled center housing
Maximum turbocharger speed: 130,000 rpm
Rotation: Standard

What’s Included

GTX3582R Gen II super core 851154-5004S with compressor housing
GT35R turbine housing kit 740902-0016, 1.06 A/R, undivided T4 inlet and V-band outlet
Gasket kit

Applications

The GTX3582R Gen II Assembly Kit is not vehicle specific. Garrett sizes it by engine and output:

Engine displacement: 2.0L to 4.5L
Power range: 450 to 900 horsepower (Garrett rating)
Manifold requirement: Undivided T4 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 130,000 rpm is at the owner’s risk and can cause damage and premature failure
More housing sizes for this core are in the GTX3582R Gen II range

About Garrett

Garrett Motion has turbocharged engines since 1955, when its T15 was matched to the Caterpillar D9 crawler, and in 1962 a Garrett turbocharger went into the Oldsmobile Jetfire Turbo Rocket, the first turbocharged production car. Garrett has supplied turbocharging in Formula 1 with Scuderia Ferrari, the FIA World Rally Championship and the 24 Hours of Le Mans. It has operated as a stand-alone company since 2018, and its technology is fitted to around 150 million vehicles worldwide.

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.
