Clutch Masters 97-01 Acura Integra GS 725 PRO Series Triple Disc Clutch w/Steel Flywheel
A turbocharged B-series Integra making several times its factory power needs a clutch that a stock-diameter single disc cannot provide. Clutch Masters part number 08913P3D7RS is the 725 PRO Series Triple Race clutch with a steel flywheel, listed here for the 1997 through 2001 Acura Integra GS. It is a drag and road race part for high-boost builds, and it is overkill for a naturally aspirated or lightly boosted car.
The Integra's hydraulic five-speed was designed around a single organic disc. The triple disc kit replaces it with three 7.25 inch rigid ceramic discs stacked with floaters in one cover, multiplying the friction surface while keeping the diameter small. A small diameter keeps rotating inertia low, which matters on a high-revving four-cylinder because the engine can gain rpm quickly between shifts.
The P3D7R in the part number is the Triple Race stage, and the S means the kit comes with a steel flywheel. Clutch Masters lists the 7.25 inch PRO clutch pack, a tool, the steel flywheel and a release bearing as included, and gives an estimated torque capacity of 900 ft-lb. The PRO version uses twelve heat-treated 4140 steel stands in place of the six aluminum posts on the earlier FX 725, a change made because the aluminum posts flexed and wore in high-horsepower use. Steel flywheels are cut from 1045 billet and black-oxide coated, and Clutch Masters states the PRO kits are SFI certified. It is a conversion kit that will not work with the Honda flywheel.
Log a high-gear pull and compare engine rpm with wheel speed, or watch the tach for a flare at the top of the boost curve. Make sure the clutch hydraulics are healthy and the pedal fully releases, and look for oil from the crank seal or transmission seal at the bellhousing, because contamination will make any clutch slip. Then match the clutch to the power. Our slipping diagnosis guide walks through separating clutch slip from other driveline faults. Many builds are better served by the 725 PRO twin disc for the Integra or a single-disc option like the FX500 6-puck kit.
Our listing is for the 1997 through 2001 Integra GS, which used the 1.8-liter non-VTEC B-series engine with the hydraulic manual transmission. Clutch Masters' application list for 08913P3D7RS is wider: 1994 through 2001 Integras with the 1.8 VTEC or non-VTEC engine except the Type R, plus DOHC 1.6 Civic models. Cars with a transmission swap, a cable-clutch conversion or a mixed-generation drivetrain need a check before ordering, so send the year, engine code and the last 7 of the VIN. Other clutch kits are in our rebuild kits department.

Clutch Masters lists 08913P3D7RS for 1994 through 2001 Integras with the 1.8 VTEC or non-VTEC engine, which takes in the LS, GS and GS-R. It is not listed for the Type R.
For most street Integras, yes. The triple disc is rated around 900 ft-lb and uses rigid ceramic discs, so it suits high-boost race builds. A twin disc or single puck clutch is a better match for moderate power.
No. This is a conversion kit that only works with the Clutch Masters steel flywheel, which is included.
Refill the B-series manual transmission with Honda manual transmission fluid.
Expect rattle and chatter at idle and a sharp, quick engagement. That is normal for a rigid multi-disc race clutch.
