What does the Boost Logic Engine Breathing System for R35 do?

It relieves crankcase pressure from the VR38DETT engine. The Engine Breathing System for R35 uses the standard vents from both valve covers and adds a banjo fitting on the oil filler neck, giving the crankcase a third place to vent. Boost Logic designed it to stop oil building up in the intercooler piping and to help the engine breathe under boost.

What is the Race Version option?

The Race Version swaps the standard fittings for high flow titanium fittings. Boost Logic sells it as an upgrade on top of the base system, and it can be combined with the Recirculation Kit. Select the fittings at checkout. Boost Logic does not publish separate flow figures for the two fitting types in its product text.

Is the Recirculation Kit required?

No. The Recirculation Kit is optional, and the base breathing system works without it. Boost Logic sells it as an add-on chosen at checkout, either on its own or together with the Race Version titanium fittings. Owners unsure which layout suits their build can ask Bulletproof Automotive to confirm before ordering.

Has the system been proven at high power?

Yes. Boost Logic states that it has used this breathing system on its 750 packages and on GT-R builds making more than 1,700 horsepower without an issue. That record comes from Boost Logic builds, so results on other cars still depend on the rest of the engine setup, the boost level and how the car is used.

Does it fit every R35 GT-R?

Boost Logic lists the system for the R35 Nissan GT-R with the VR38DETT engine, which covers the 2009 and later cars. It connects to the factory valve cover vents and the oil filler neck, and no engine machining is described. Cars with modified valve covers or unusual intake layouts should confirm fitment with Bulletproof Automotive first.

Description

Boost Logic Engine Breathing System for R35 Nissan GT-R

Boost Logic’s Engine Breathing System for R35 Nissan GT-R vents crankcase pressure from the VR38DETT through the standard vents on both valve covers plus an added banjo fitting on the oil filler neck, a third vent path aimed at relieving as much crankcase pressure as possible. Boost Logic built it to stop oil collecting in the intercooler piping and has run it on its 750 packages and on GT-Rs making more than 1,700 horsepower without an issue. That record points it at boosted, modified cars where crankcase pressure climbs with power; it is less of a priority on a car still at factory output.

Design and Performance

The system keeps the factory valve cover vent points and adds a banjo fitting off the oil fill neck, so crankcase gases leave the engine from three places instead of two. Boost Logic offers two upgrades on top of the base kit, a Race Version with high flow titanium fittings and a Recirculation Kit, and both are chosen at checkout.

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.
