Which stroke option do I need for the Boost Logic VR38 Pistons for R35?

Choose 3.8L Standard Stroke for an engine with the factory VR38DETT crankshaft, or 4.1L 94mm Stroke for an engine built with a 94mm stroke crankshaft. Boost Logic offers the VR38 Pistons for R35 in a version for each, so the choice must match the crank in the build. Both versions are the same price.

How many pistons are in the set?

The price covers a set of six pistons, one for each cylinder of the VR38DETT V6. The Boost Logic product photo also shows rings and wrist pins with the pistons, but the listing text does not say they are included, so confirm the full contents with Bulletproof Automotive before planning the engine build.

What compression ratio are the pistons?

Boost Logic does not publish a compression ratio, bore size or material for these pistons in its listing. Engine builders who need those details for a build sheet or a tune should ask Bulletproof Automotive to confirm them with Boost Logic before ordering, since the right compression depends on fuel and boost targets.

Can I install these pistons without taking the engine apart?

No. Pistons are internal engine parts, so the engine has to be removed and disassembled, with the bores measured and prepared by an engine builder before the new pistons are fitted. Plan them as part of a full VR38DETT rebuild, usually alongside rods, bearings and other bottom end work.

Do the pistons work with the Boost Logic stroker kit?

The 4.1L 94mm Stroke version is intended for VR38 engines built with a 94mm stroke crankshaft, the stroke Boost Logic lists for its 4.1 option. Boost Logic also sells a 4.1L stroker kit and a complete 4.1 stroker short block, so confirm with Bulletproof Automotive whether those already include pistons before ordering both.

Description

Boost Logic VR38 Pistons for R35 Nissan GT-R

Boost Logic’s VR38 Pistons for R35 Nissan GT-R are sold as a set of six for the VR38DETT, in a version for the standard 3.8-liter crankshaft or for a 4.1-liter build with a 94mm stroke crank. Boost Logic publishes little more than that, so this listing is for engine builders who already know the specification they want and need the correct piston for the crank in the build. Buyers after a complete rotating assembly or a finished bottom end should look at the Boost Logic stroker kit or short blocks instead.

Versions for the standard 3.8L stroke or a 4.1L 94mm stroke crankshaft

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.
