Is the V-band G45 Turbine Housing Kit right for a single-scroll manifold?

Yes. A single-entry manifold or log ending in a V-band collector is exactly what this G45 Turbine Housing Kit is built for, since its inlet has no divider. Owners with a twin-scroll manifold and a divided T4 flange should order the T4 version, offered from 1.01 up to 1.44 A/R.

How quickly will a 1.01 A/R housing spool?

Faster than any other G45 size. The small passage speeds exhaust into the 89mm turbine wheel, so boost builds earlier than with the 1.15, 1.28 or 1.44 A/R housings. The cost is more backpressure near redline, which large engines feel most.

Can the housing be clocked?

Yes. With V-band clamps at the inlet and the outlet, the housing rotates relative to the manifold and downpipe during the mock-up. That makes it easier to align the downpipe and wastegate plumbing in a tight space before the clamps are tightened.

Do the G-Series II and GXR45 cores share this housing?

Yes. Garrett states that G-Series II uses the first-generation turbine housings and that the GXR45 cores use the same T4 and V-band housings as the G-Series. This one housing fits all nine G45 family cores Garrett lists, so it can stay on the engine through a core upgrade.

Do I need an external wastegate?

Yes. The housing is free float, with no wastegate port inside. Boost is controlled by an external wastegate on the exhaust manifold ahead of the turbine, which has to be bought separately and sized for the target boost. The manifold needs a wastegate flange to suit.

Description

Garrett G45 Turbine Housing Kit, 1.01 A/R V-Band Inlet and Outlet

Garrett’s G45 Turbine Housing Kit with V-band inlet and outlet in 1.01 A/R is the quickest-spooling single-scroll housing for the G45, a stainless steel casting with clamped joints and an external wastegate layout. Garrett lists it for nine standard-rotation cores, including the G-Series II G45-1610 and the five G-XRace GXR45 cores. A fabricated single-entry manifold on an engine at the smaller end of the G45 range, built for response, is where it belongs. A large engine aiming at the top GXR45 ratings will outgrow it quickly.

Features

Undivided V-band inlet and V-band outlet
Free-float design with no internal wastegate
Smallest V-band size in the G45 Turbine Housing Kit 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.
