How much power can the HD EXEDY Stage 1 Organic Clutch hold on an FD3S?

EXEDY rates the 10802HD at 348 lb-ft of torque capacity at the wheels and 435 lb-ft at the flywheel, from a clamp load of 2,653 lb. That is about 27 percent more than the standard 10802, enough for an FD with raised boost or a single-turbo conversion that stays on the street.

Do I need a counterweight with an EXEDY lightweight flywheel on the FD?

Yes, when the EXEDY ZF01 flywheel is fitted. The 13B rotary is balanced through its flywheel, and Turn 14 lists adapter and counterweight N351-11-521 for the FD3S with the ZF01. With the factory flywheel retained, the 10802HD fits without an additional counterweight.

Is the HD Stage 1 clutch still comfortable on the street?

Yes, with a heavier pedal. The 10802HD uses the same organic facing and sprung hub as the standard EXEDY Stage 1 Organic Clutch, so engagement stays smooth, but its 2,653 lb clamp load raises pedal effort noticeably. An FD that rarely sees more than stock boost will be easier to live with on the 10802.

What is the difference between the 10802HD and the standard 10802?

The 10802HD clamps at 2,653 lb against 2,093 lb for the standard kit, lifting the wheel rating from 275 to 348 lb-ft. Both use a 236 mm organic disc. Turn 14 lists the HD spline as 23 tooth, 26.4 mm and the standard kit as 23 tooth, 26.2 mm, so both suit the factory FD gearbox.

How hard is it to replace the clutch on an FD3S RX-7?

It is a transmission-out job, and the FD power plant frame makes it slower than most rear-drive cars. A rotary specialist or an experienced home mechanic with a lift is the right fit. Check the flywheel and its counterweight while the gearbox is out, since they balance the rotating assembly.

Description

EXEDY Stage 1 Organic Clutch Kit for FD3S Mazda RX-7 (HD)

EXEDY’s Stage 1 Organic Clutch Kit for FD3S Mazda RX-7 in HD form clamps at 2,653 lb, enough for 348 lb-ft at the wheels by EXEDY figures, while keeping the organic disc that makes a Stage 1 civil in traffic. It fits the FD that has moved on from stock boost but is still driven on the street rather than trailered.

Design and Performance

Clamp load rises to 2,653 lb from 2,093 lb on the standard kit, and EXEDY lists 546 lb-ft of clutch torque capacity and 435 lb-ft at the flywheel. The 236 mm organic disc still rides on a sprung hub, so the extra capacity shows up at the pedal as more effort rather than as harsher engagement.

Features

Heavy-duty ductile-cast pressure plate, 2,653 lb
Organic facing on a sprung center hub
Rated 435 lb-ft at the flywheel
Firmer pedal than the standard FD Stage 1
SFI 1.1 compliant, according to EXEDY

Specifications

Disc diameter: 236 mm
Input spline: 23 tooth, 26.4 mm
Clamp load: 2,653 lb
Clutch torque capacity: 546 lb-ft
Torque capacity at the flywheel: 435 lb-ft
Torque capacity at the wheels: 348 lb-ft

Applications

Mazda RX-7: FD3S | 1993-1995 | 1.3L twin-turbo rotary

Notes

When the EXEDY ZF01 lightweight flywheel is used, Turn 14 calls for adapter / counterweight N351-11-521
For a lighter pedal on a lightly modified car, choose the standard EXEDY Stage 1 Organic Clutch Kit for the FD3S RX-7

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.
