Why does the DOHC conversion need a new engine mount bracket kit?

NISMO leans the engine 12 degrees to the left, instead of the factory 12 degrees to the right, to make room for the intake system on its DOHC head, sold separately. The NISMO Engine Mount Bracket Kit sets that 24-degree change in an S30 or S31, and works with the NISMO Oil Pan Kit, which clears the suspension member at the new angle.

What comes in the NISMO engine mount bracket kit?

A right and a left engine mount bracket with eight Nissan genuine bolts. The transmission and transmission mount for the new engine angle are not part of the Engine Mount Bracket Kit; NISMO leaves both to the builder, who makes or sources them for the 12-degree left tilt.

Can I buy the brackets without the NISMO DOHC kit?

No. NISMO sells its S30 and S31 option parts only to customers who have bought the DOHC cylinder head conversion kit, part 10000-RRS00. The brackets have no purpose on a single-camshaft L-series engine, which keeps its factory lean to the right.

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

The US cars are built on the S30 chassis these brackets were 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.

What else changes when the engine angle changes?

The oil pan and the transmission. NISMO pairs the brackets with its Oil Pan Kit, shaped to clear the suspension member at the new angle, and states that the gearbox and its mounting must be made or sourced for the 12-degree left tilt. The propeller shaft is also left to the builder.

Description

NISMO Engine Mount Bracket Kit for S30 / S31 Nissan Fairlady Z with NISMO DOHC Head

NISMO’s Engine Mount Bracket Kit for the S30 / S31 Nissan Fairlady Z sets the engine at the angle the NISMO DOHC conversion needs. The factory L-series leans 12 degrees to the right; to clear the intake system on its twin-cam head, NISMO leans the engine 12 degrees to the left instead, a 24-degree change made at these two brackets. They are the first part to plan around in an S30 build, because the oil pan, the transmission and its mounting all follow from where the engine sits, and they have no use in a car keeping its single-cam head.

Features

Right and left brackets made as a matched set
Leans the engine 12 degrees toward the left-hand side, the opposite of the factory lean
Designed by NISMO for the S30 / S31 Fairlady Z with its DOHC head
Eight Nissan genuine mounting bolts supplied

What’s Included

Right engine mount bracket
Left engine mount bracket
Hex bolts (x8)

Applications

Nissan Fairlady Z: S30 / S31 | 1969-1978 | L28 with the NISMO DOHC head

Notes

Requires the NISMO DOHC Cylinder Head Conversion Kit; NISMO sells this part only to buyers of the kit
The new engine angle also needs the NISMO Oil Pan Kit and a transmission and transmission mount set up for the 12-degree left tilt, which the builder sources
For the S30 / S31 only; NISMO has not confirmed the Engine Mount Bracket Kit on other L-series cars such as the GC10 Skyline
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 Intake Manifold Kit and NISMO Exhaust Manifold are the other NISMO parts listed for an S30 engine build
No warranty beyond initial defects, and delivery can take time because NISMO limits monthly production

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.
