Are the Boost Logic 4.1L Crate Motors for R35 also offered in 3.8L?

Yes. Boost Logic offers the Stage 2 engine in the factory 3.8 liter displacement or at 4.1 liters, and both are priced the same. The larger displacement adds swept volume, which generally brings more torque at a given boost level. Discuss the choice with the tuner, since it affects turbo sizing and calibration.

What do the core options mean?

The Good Used Core Exchange option builds the engine on a used VR38DETT core and is priced at 32,499 dollars. The New OEM Core option starts from a new factory engine and costs 49,999 dollars. Boost Logic does not publish its core acceptance terms, so Bulletproof Automotive confirms the exchange details with Boost Logic at the time of order.

What parts go into the Stage 2 engine?

Boost Logic does not publish a build sheet or power rating for the Stage 2 engines on its product page. Bulletproof Automotive confirms the full specification with Boost Logic before the order is placed. For a published parts list, the Boost Logic Stage 1 3.8L crate motor lists its heads, rods, pistons, camshafts and studs in full.

Are turbochargers and a tune included?

They are not listed. The engine is sold as a crate motor, and the turbochargers, fuel system upgrades and engine calibration are planned separately with the tuner. Boost Logic sells complete R35 turbo kits and fuel parts, and Bulletproof Automotive can quote those alongside the engine so the whole package is planned together.

How is the engine shipped?

The 4.1L Crate Motors for R35 ship by freight rather than parcel service, since the engine weighs about 300 lbs. Bulletproof Automotive arranges delivery to a commercial address or the installing shop, and confirms the delivery details and any core return before the engine leaves Boost Logic in Austin.

Description

Boost Logic Stage 2 3.8L / 4.1L Crate Motors for R35 Nissan GT-R

Boost Logic’s Stage 2 3.8L / 4.1L Crate Motors for R35 Nissan GT-R are Boost Logic built VR38DETT engines offered in the factory 3.8 liter displacement or at 4.1 liters, both at the same price. Each is available on a good used core exchange or on a new OEM core, which adds $17,500. Boost Logic publishes no build sheet or power rating for the Stage 2 engines, so the specification is confirmed with Boost Logic through Bulletproof Automotive before ordering. The listing suits an owner who has already settled on a Boost Logic engine at the Stage 2 level; a buyer comparing on published specifications will find a full parts list only on the Stage 1 3.8L engine.

It designs turbo systems, titanium exhausts, intercoolers and engine components for the Toyota Supra, Porsche 911 Turbo, Nissan GT-R, Ferrari and Lamborghini, and its R35 GT-R builds have trapped over 180 mph in the quarter mile and over 200 mph in the half mile.

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.
