Does the NISMO Exhaust Manifold for S30 cars come with a heat shield?

No. The NISMO Exhaust Manifold for S30 and S31 cars has no heat shield, so NISMO requires heat shielding and insulation on the strut towers, the underside of the hood and other nearby parts. The manifold fits only the NISMO DOHC cylinder head, sold separately.

What size are the tubes on the NISMO six-into-two manifold?

The primaries are 45mm and the secondaries 50mm, in SUS304 stainless steel tube laid out as an equal-length six-into-two manifold. It carries two bosses for air-fuel ratio sensors for tuning the engine, and the first-generation NISMO logo also used on the conversion kit rocker cover.

Are gaskets and studs included with the exhaust manifold?

They come with the DOHC conversion kit, which supplies two metal exhaust manifold gaskets with 24 studs and 24 nuts. The exhaust manifold itself is sold as the main unit only, and the rest of the exhaust system after the manifold, including the muffler, is sourced by the builder.

Is the stainless manifold polished?

No. NISMO leaves the manifold unpolished, so streaks and other marks from the manufacturing process can remain on the tube. NISMO states this before purchase so that the raw stainless finish is not mistaken for a defect when the manifold arrives.

Will the manifold fit a US Datsun 240Z or 280Z?

The US cars are built on the S30 chassis this manifold was designed for, but NISMO developed and tested the conversion only on Japanese-specification right-hand-drive cars. For left-hand-drive cars NISMO directs owners to the shop installing the engine, the same specialist NISMO requires to be named when the kit is ordered.

Description

NISMO Exhaust Manifold for S30 / S31 Nissan Fairlady Z with NISMO DOHC Head

NISMO’s Exhaust Manifold for S30 / S31 Fairlady Z cars with the NISMO DOHC head is a six-into-two, equal-length manifold in SUS304 stainless steel tube, with 45mm primaries feeding 50mm secondaries and two bosses for air-fuel ratio sensors. It is built for the S30 engine bay with the engine leaning 12 degrees to the left, and it wears the first-generation NISMO logo. NISMO leaves it unpolished and without a heat shield, which suits a builder who will finish the engine bay to their own standard.

Notes

Requires the NISMO DOHC Cylinder Head Conversion Kit; NISMO sells this part only to buyers of the kit
Sold as the manifold only; the gaskets, studs and nuts come with the conversion kit
No heat shield is fitted, so the strut towers, hood underside and nearby parts need heat shielding and insulation
The manifold is not polished, and marks from manufacturing can remain on the tube
The Exhaust Manifold for S30 / S31 cars fits only those models; the muffler and the rest of the exhaust are sourced by the builder
Developed and tested on Japanese-specification right-hand-drive cars; Datsun 240Z, 260Z and 280Z export models share the S30 chassis but are not confirmed by NISMO
The NISMO Engine Mount Bracket Kit, NISMO Oil Pan Kit and NISMO Intake Manifold Kit are the other NISMO parts listed for an S30 engine build

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.
