FAQ
What is the ACR-2101?It identifies this Stage 5 2MS clutch kit for the specified Toyota MR2 turbo application. Match the vehicle details before ordering.
Will this fit my Toyota MR2?It fits 1991 to 1995 Toyota MR2 models with the 2.0L 3S-GTE turbo engine and a manual transmission. It does not fit a non turbo engine or an automatic transmission.
What clutch disc configuration is included?The package includes a six puck sprung ceramic disc. Ceramic material provides aggressive engagement and increased holding capacity for track focused use.
How much holding capacity does the kit provide?The stated increase is 200 percent over the factory kit, measured at crank torque. Actual results depend on engine output, vehicle setup, and driving conditions.
Is this suitable for daily driving?It is designed for race applications and heavy track use, with light street use after proper break in. Ceramic friction material can feel harsher and less forgiving than an organic street clutch.
Does the listed package include a flywheel?A flywheel is not included in the listed package contents. Inspect the existing flywheel and resurface or replace it as needed before installation.
What bearings are included?The listed contents include a release bearing and a pilot bearing or bushing when applicable. Confirm the vehicle requirement before installation.
What break in procedure should I follow?Drive about 500 street miles while keeping engine speed below 4,500 rpm, using no more than half throttle, and using no boost when applicable. Avoid hard launches and track use until the disc is bedded.
Can clutch chatter occur?Some chatter can occur during early use because of the ceramic friction material. It should be minimal after the disc is correctly bedded in.
Does the package include installation hardware?The listed contents include a clutch alignment tool, release bearing, pilot bearing or bushing when applicable, an information sheet, and Action Clutch swag. Verify any vehicle specific bolts or replacement hardware separately.
What should I verify before ordering?Confirm the model year, Toyota MR2 model, 2.0L 3S-GTE turbo engine, manual transmission, and intended use. A different engine, transmission, or model year can require a different clutch application.
Installation Instructions
- Confirm the vehicle application and match the order to ACR-2101 before opening the package.
- Disconnect the battery, chock the wheels, raise the vehicle, and support it securely on rated stands.
- Remove the components that block transmission removal, then disconnect the shift linkage, clutch hydraulics, wiring, and sensors connected to the transmission.
- Support the engine and transmission, remove the mount and cross member, then separate the transmission from the engine.
- Remove the pressure plate evenly, take out the old disc, and inspect the release fork, pivot, pilot bearing, and rear main seal.
- Inspect the flywheel for heat damage, warping, or glazing. Resurface or replace it when needed, then clean the friction surface with suitable brake cleaner.
- Place the new disc in the correct direction with the alignment tool, then position the pressure plate over the locating dowels.
- Tighten the pressure plate in stages using the vehicle service manual sequence and torque specification. Remove the alignment tool after the pressure plate is secure.
- Install the release bearing and the pilot bearing or bushing when applicable. Inspect the fork and pivot, then apply only the lubricant specified for the contact points.
- Reinstall the transmission, mount, cross member, linkage, hydraulics, wiring, and sensors. Refill the transmission fluid and bleed the clutch hydraulic system.
- Complete the break in with about 500 street miles below 4,500 rpm, at no more than half throttle, and with no boost when applicable. Avoid hard launches and track use until the friction material is bedded.
