Why does the DOHC conversion need the NISMO Oil Pan Kit for S30 cars?

With the engine leaning 12 degrees to the left on the NISMO Engine Mount Bracket Kit, the factory pan would interfere with the suspension member. The NISMO Oil Pan Kit for S30 and S31 cars clears it at the new angle, and works only with the NISMO DOHC head kit and those brackets, both sold separately.

How much oil does the NISMO oil pan hold?

The cast aluminum pan holds 5.1 liters, about 5.4 US quarts. NISMO supplies a dedicated oil level gauge and a dedicated strainer with the kit, so the oil level is read against the pan it was made for rather than against the factory dipstick.

What does the baffle plate in the oil pan do?

The baffle plate carries six rubber flaps that hold oil around the strainer when it surges under hard cornering and braking. NISMO added it to stop the drop in oil pressure that an uneven oil level causes during circuit driving.

Can I fit the oil pan without the NISMO DOHC head?

No. NISMO sells its S30 and S31 option parts only to customers who have bought the DOHC cylinder head conversion kit, and the pan is shaped for an engine leaning 12 degrees to the left on the NISMO Engine Mount Bracket Kit rather than for the factory engine angle.

What engine oil does NISMO recommend for the DOHC engine?

NISMO recommends NISMO Competition Oil 5W-40, made by MOTUL, and ran its prototype engine on Type 2193E in that grade. For an engine used mainly on track, NISMO also recommends a teardown and inspection every 1,000 miles, about 1,600 km.

Description

NISMO Oil Pan Kit for S30 / S31 Nissan Fairlady Z with NISMO DOHC Head

NISMO’s Oil Pan Kit for S30 / S31 Nissan Fairlady Z cars running the NISMO DOHC head replaces the factory sump with a cast aluminum pan shaped to clear the suspension member once the engine leans 12 degrees to the left. NISMO used the change to improve the part as well: a gusset cast into the transmission mounting face stiffens the joint between engine and gearbox, and a rubber-flapped baffle keeps oil at the pickup when a circuit car loads up in long corners. On a twin-cam S30 it is a required part, and on a car keeping its single-cam engine it does not apply.

Cast aluminum pan holding 5.1 liters
Gusset cast into the transmission mounting point for a stiffer engine-to-gearbox joint
Baffle plate with six rubber flaps
Dedicated oil strainer and oil level gauge

Notes

Requires the NISMO DOHC Cylinder Head Conversion Kit; NISMO sells this part only to buyers of the kit
Made for the engine angle set by the NISMO Engine Mount Bracket Kit, and fitted together with it
For the S30 / S31 only; NISMO has not confirmed the Oil Pan Kit for S30 cars on other L-series vehicles such as the GC10 Skyline

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.
