Which stage of the Long Block for R35 should I choose?

Stage 1 strengthens the bottom end with Manley parts on factory heads. Stage 2 adds valve springs, a harmonic damper and GT1R camshafts. Stage 3 moves to CNC ported heads, and Stage 6 adds a billet crank, aluminum rods and girdle. Bulletproof Automotive can help match a stage of the 3.8L Long Block for R35 to the power target.

What machine work is included?

Every stage includes all of the machine work on the short block, balancing of the rotating assembly, blueprinting and assembly of the long block. Stage 1 also includes cleaning and inspection of the factory cylinder heads, and later stages add the head work listed for each stage.

When do the heads get ported?

From Stage 3. Stage 3 and Stage 6 use GT1R CNC ported and polished heads with a 3 angle valve job, Ferrea high pressure springs, oversize stainless valves, titanium retainers, spring locators and bronze guides. Stage 1 keeps the factory heads, and Stage 2 upgrades their springs and camshafts.

Do I need to supply an engine?

Yes. A good working core engine is required, and the price does not cover a core engine, teardown or cleaning of a customer engine. T1 Race Development has options for buyers who cannot supply a core, which Bulletproof Automotive can arrange.

What does the powdercoat option cover?

It covers the valve covers, all front timing covers and the upper and lower intake manifold, including the shipping and prep time around coating. T1 usually finishes its engines in wrinkle black, and a wide range of other colors is available on request.

Description

T1 Race Development GT1R 3.8L Long Block for R35 Nissan GT-R

T1 Race Development’s GT1R 3.8L Long Block for R35 Nissan GT-R keeps the factory displacement and builds the VR38 in four stages, from a Manley bottom end on stock heads to a fully reinforced engine with a GT1R billet crank. T1 builds each engine from a core supplied by the customer, with the bottom end machined, balanced and blueprinted before the heads go on.

Choosing a Stage

Stage 1 uses Manley pistons, rings, upgraded pins and rods, a GT1R head and main stud kit and OEM bearings, with the factory heads cleaned and inspected. Stage 2 adds a GT1R harmonic damper and fits the heads with Ferrea high pressure springs, titanium retainers, spring locators and GT1R camshafts. Stage 3 keeps that bottom end and moves to GT1R CNC ported and polished heads with a 3 angle valve job, oversize stainless valves and bronze guides.

Stage 6

Stage 6 is T1’s most extreme 3.8 liter build, with GT1R block reinforcement, a GT1R billet crank, GT1R aluminum rods, GT1R high compression pistons with C350 wrist pins, a GT1R chromoly main girdle and main studs, GT1R head studs, harmonic damper and oil pan, topped by the Stage 3 head specification with GT1R BIG camshafts.

About T1 Race Development

T1 Race Development was founded in Texas in 2005 by Tony Palo, whose 2000 Acura Integra GSR became the first eight-second front-wheel-drive street car before the shop turned its attention to the Nissan GT-R. T1 went on to become the first to exceed 230 mph in the half mile in a GT-R and the first to make 2,400 whp from the VR38DETT, and it now develops engines, drivetrain parts and complete builds for the R35 GT-R, Lamborghini Huracan and Audi R8.

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.
