B3 Clutch Upgrade?

[Sid_RallyX_82]

Hey guys, I poked around the forum a bit looking for where to get a better clutch, but it seems like any time someone even mutters the words "B3" and "upgrade" in the same sentence everyone immediately tells them to swap. I'm not looking to get much out of this engine, I'm just wondering if anyone knows where to get a lighter/stronger/better flywheel, clutch, and pressure plate. I'm not doing launches on the 1320, just looking for a little more fun in the canyons. Thanks guys

Sounds to me like you need to keep the Festiva flywheel and up grade the clutch and pressure plate to an Exedy kit that you can find on E-bay for around $118.00 Good luck

Wut he sed. You don't need more clutch with a stock B3, a SOHC B6, or even a B6D if you're not launching it.

Is yours slipping now? If you need to replace it probably an exedy and get your flywheel machined true again is what you need. Also check if the cause for slipping is the clutch actually worn or oil leaking onto it from valve cover gasket, distributor seal, crank seal or transmission input shaft seal.

It's not slipping, just starting to wear a little thin, high pedal engagement, so I figured when I replace it, why not upgrade? I wanted something lighter to reduce the engine's moment of inertia, but with as much or more tension on the pressure plate as the stock one so I can bang shifts quicker. Does Dickmeyer have a drilled flywheel? Or where can I get a light one?

Rock Auto has the Exedy Kit for $98, but it looks like it's just an OE replacement. Is there anything better about it?

Quick shifts are a waste of time, get an Exedy disc when needed and drive it like your time is valuable!

[Sid_RallyX_82]

I don't understand what you mean

[Dragonhealer]

Quick shifts use up the equipment very fast, then someone has to fix it.
as we have a lot of students, I have too much practice replacing gearbox parts, clutches, and shifter parts. There are better ways to make her fast. JMHO

You could get any racing clutch like this for example: http://www.ebay.com/itm/310321836974
I believe the reason no one else does is that a lighter flywheel and a grabby clutch will break your e-series transmission very quickly.

Besides which, there are a lot of people who are unhappy with the Spec clutches. Just go Exedy.

The pressure plate clamping force is significantly higher than stock. And you can mill the flywheel down to about 10 lbs (16 stock), but I would go to 12 for longevity.

Ok, I'm getting confused.
First, what do you mean by Quick Shifts? What I do doesn't feel very harsh for the drivetrain. I always try to be smooth when being quick

Second, how is a lighter flywheel bad for the trans? I would think it reduces shift shock because the shaft and crank can rev match easier...
Sorry for not being savvy and thank you for your experience and patience

The flywheel weight has to do with harmonics and stored energy (lots of maths). True, lightening the flywheel will reduce it's polar moment, but it also reduces it's kenetic energy that's used for the up shifts.

One of the main purposes of flywheel mass is to absorb resonant harmonic frequencies from the engine. The flywheel mass is calibrated to work with the engine. Changing that mass will change the harmonic cherictaristics of the flywheel and this usually results in more driveline failures.
I don't like the way cars with lightened flywheels shift. The flywheel mass makes upshifts feel notchy, and the cars become harder to match on downshifts because they are too touchy. Rev matching has 2 purposes. First, it makes gear engagement easier, but on a synchronized tranny this is less critical. Second (and of most importance in a ultra light FWD car) it adjusts the amount of engine braking that is applied when the clutch is released. The rate of clutch release is critical to adjust the amount of decel. I often use downshifts to set the front end in a corner, rather than braking, because I can pivot the car and then be in the sweet spot to power out. I need a nice smooth and predictable drive line to do this effectively. Lightened flywheels make this more tedious.
Rather than worrying about shifting fast, I'd be concerned with chassis setup that allows higher entry speeds, so less shifting is needed.
