Does the TS3BW Clutch for JZA80 need anything else to fit?

Yes. The TS3BW Clutch for JZA80 is a push-type clutch and the JZA80 six-speed uses a pull-type release from the factory, so it is installed with the OS Giken Movement Alteration Kit for JZA80 (TY031-ALT). Turn 14 lists a kit as required; our team can confirm the pairing before you order.

What does the heavier flywheel do?

The extra flywheel mass keeps the engine turning between gear changes instead of letting revs drop quickly. OS Giken USA says that helps keep the turbocharger in its ideal boost range, which matters most on a large turbo that is slow to spool.

How much power will it hold?

OS Giken USA rates the TS3BW at about 700 lb-ft of torque, the same as the TS3B. It is designed for turbocharged and supercharged engines and suits a built 2JZ-GTE that needs more capacity than a twin plate offers. Our team can help choose.

What does TS3BW mean?

It is the OS Giken model code. TS is the cover series, 3 is the number of discs, B is the 204mm disc size and W marks the heavier flywheel. There is no D suffix, so the discs have solid hubs for direct engagement.

Is it suitable for street driving?

The pressed-steel TS cover keeps pedal effort moderate, and the heavier flywheel makes pulling away smoother than a lightweight setup. Solid-hub discs pass more driveline noise than damped ones, so expect a firmer, more connected feel than stock. Our team can advise.

Description

OS Giken TS3BW Clutch for JZA80 Toyota Supra 2JZ-GTE, Triple Plate with Heavier Flywheel

OS Giken’s TS3BW Clutch for JZA80 Supra builds pairs the TS series triple plate clutch with a heavier flywheel, a combination OS Giken designed for turbocharged and supercharged engines. The three 204mm discs give the capacity, rated by OS Giken USA at about 700 lb-ft, while the extra flywheel mass carries engine speed through each gear change, which OS Giken USA says helps keep the turbocharger in its ideal boost range. On a big-turbo 2JZ-GTE that falls off boost between shifts, that can make the car easier to drive quickly on the road and at the track.

What the W Adds

In OS Giken code the W suffix marks the heavier flywheel. Compared with the TS3B for JZA80, which uses the same three discs and cover for sharper engine response, the TS3BW gives up some of that quick revving in exchange for holding engine speed and boost between shifts. Choose by how the car is driven.

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.
