Talking Help me pick out a new clutch

Hey everyone,

I have no idea what clutch to get. I'll probably be replacing my transmission soon and I thought now would be a good time to change the clutch out as well.

Firstly, newbie question: What else do I need to replace with the clutch? Flywheel? Pressure Plate? None of the above? All of the above? Something else?

Secondly, I have a basically stock 88' N/A. Only real "mod" is a Prelude CAI running into my passenger-side fender-well.

I want to keep the car very streetable but I plan on autocrossing her sometime this year or next.

Also, I'd like the clutch pedal to feel a bit more stiff than it does right now. Would a different clutch achieve this? Or is that pressure built into the hydraulic system?

Thanks for the help guys, give me your suggestions.

Cheers,

get the ACT street clutch disc and pressure plate and you may need to resurfice your flywheel or if you have the money buy a light weight flywheel...

Good bang for buck. Good for lightly modified cars.

I personally had good luck with the Centerforce dual friction.. <lights fuse and runs>

yeah the ACT will give you the perfect pedal feel that your looking for..how stiff the pedal is will be determined by what pressure plate you use...if i were you i would put a new pilot bearing in it while you have it apart and u should buy a new release bearing with the clutch kit

I have an ACT pressure plate. I don't recall the name, but it has 34% more clamping force that stock. I use the stock exedy clutch with this and it is excellent. I used it with my rebuilt engine that was probably putting down 160+ to the wheels for 25k miles. If never slipped once and had very good pedal feel and excellent driving characteristics. I never had any problems starting the car anywhere, no matter the incline. It was heavily abused for a good bit of that 25k miles, and it is still within the re-usable specs.
Seeing all that, I see no reason at all to use anything other than the stock clutch when you upgrade the PP.
Edit: Here are the notes on the Mazdamotorsports site, which is where it was bought from:
225mm ACT Pressure plate, MZ-013, has 34 percent more clamping force than stock unit. Rated at 268 ft-lbs. of torque with stock disc or ACT "Street" Disc 0000-02-3444-AC
I don't think an NA rotary will get anywhere near 268 ft-lbs of torque, so either the stock clutch or a regular "street" one should be fine.

I'll sell you my clutch and pressure plate for half the price advertised.

Only drawback is it has like 5k on it. Motor blew before I had a chance to really use it.

PM me if you're interested. I liked it...

Oh yeah... it's the ACT street/strip clutch and HD pressure plate.

While you have it apart, replace everything in that area. This includes:

*Resurfacing the flywheel. Take it off, take it to a decent machine shop. This isn't technically required, but it's a good idea, especially if you're putting a new clutch in.

*Replace the throwout bearing.

*Replace the pilot bearing (in the e-shaft).

*Replace the clutch/pressure plate.


As for clutch/pressure plate, I've been very happy with the Racing Beat street/strip clutch/pressure plate combo. It's a full face organic with better clamping pressure than stock, but it's still quite drivable, and it handles all the power I'm throwing at it (140 dyno'd to the wheels) just fine. The only complaint I have is that it starts getting a bit grabby when hot (say, Chicago stop and go traffic during the summer).

There is a guy selling new clutches in the for sale part of the thread for a damn good price, go look it up. Something like "new stuff used price" is the title i think.
