Is the 1.5-Way LSD for EG6 made for US-market Civics?

No. The 1.5-Way LSD for EG6 cars is engineered for the Japanese-market EG6 Civic SiR with the B16A engine and its transmission, and it may not fit a US-market EG Civic. If your car has a swapped drivetrain, confirm the transmission details with Bulletproof Automotive before ordering.

What oil does the differential need?

The manufacturer recommends a 100 percent synthetic differential oil, with 75W-140 as the base viscosity, adjusted to how the car is used. Performance can change dramatically with the wrong oil, and an unsuitable oil can lead to damage, so check the recommendation carefully before filling the gearbox.

How noisy is it in parking lots and around town?

Quieter than most mechanical units. The manufacturer designed it to reduce the chattering noise that is a common drawback of mechanical limited slip differentials on the street, and to avoid the vibration and unsettled behavior large plates can cause in tight turns. It is meant to be easy to live with on the road.

Why a 1.5-way instead of a 2-way?

A 1.5-way locks fully under acceleration but only mildly when you lift, which the manufacturer chose as ideal for front-drive cars. The car stays stable on corner entry while still getting strong traction on exit, and lockup builds with the throttle rather than depending on a high initial torque setting.

Can I install it myself?

Professional installation is recommended. The work requires the factory service manual for the car and careful attention to every step. After fitting, the differential needs a full break-in period, and any unusual vibration or noise while driving means stopping in a safe place for inspection straight away.

J’s Racing 1.5-Way LSD for EG6 Honda Civic

J’s Racing’s 1.5-Way LSD for EG6 Civic SiR builds is the Osaka tuner’s mechanical differential for front-drive Hondas, sold in Japan as the 1.5way High Traction L.S.D. A 1.5-way unit locks fully under power and works mildly off throttle, which J’s Racing considers the right balance for an FF car. Rather than chasing a high initial torque, the design relies on the inherent cam locking action, so lockup follows the throttle and the car stays settled. It is the part that turns a B16A Civic into a car that can drive out of slow corners; for a stock commuter it is more than needed.

Construction

The clutch plates are J’s newly developed RS plates, made by a special process that improves torque transfer while staying quiet. The differential case is machined from carefully selected forged material with quality held to 1/100mm, and the pinion and side gears use high-strength gear steel with special heat treatment. J’s Racing’s own team runs the off-the-shelf unit in Super Taikyu, where it has taken a Class 4 win.

Features

1.5-way locking: full effect on throttle, mild effect off throttle
Cam angles of 45 and 25 degrees with a 6.5 kg cold initial setting
Low chatter on the street compared with typical mechanical LSDs
Forged differential case built to handle high-output engines
Grips even when riding over curbs, letting the throttle control the car’s attitude

Applications

Honda Civic SiR: EG6 | 1991-1995 | 1.6L B16A

Notes

J’s Racing designs this part for the JDM EG6 Civic with the B16A engine; it may not fit the US-market EG Civic
Use a 100 percent synthetic differential oil; J’s Racing gives 75W-140 as the base viscosity, which can change with how the car is used
Professional installation with the factory service manual is recommended, followed by a thorough break-in
Stop and inspect the car immediately if unusual vibration or noise appears while driving
Assembled in Japan and supplied through J’s Racing USA; once your order is placed, Bulletproof Automotive confirms availability and quotes the lead time

About J’s Racing

J’s Racing was established in Osaka in 1989, as VTEC engines and lightweight Civics and Integras were changing what a Honda could do, and it has built parts for Hondas ever since. The company develops engine response, suspension, braking, cooling and aerodynamics together as one system, then proves the parts in time attack, gymkhana, endurance and circuit racing. Its Fit lapped Tsukuba Circuit in 1’00.459, and its naturally aspirated AP1 S2000, the Maou car, became the company’s reference build for the Honda roadster. Every J’s Racing part is designed and tested in Japan, and J’s Racing USA in Carson, California handles distribution in the United States.

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.
