I love my Exedy 1. It's been fun, responsive, and perfectly reliable for about....35K miles.

I put the same clutch in about year ago and really like it. It's smooth enough for a daily driver, but holds turbo-level power comfortably. I'm not sure where the power limit is, but I'll try and find out as I upgrade my setup next year.

The flywheel bolt is a reverse torx style, not real common but you can find sockets at most tool or auto parts stores.

I was able to drop the trans with the subframe in place, but I ended up removing it for the install. Too much hassle otherwise. If I did it again, I'd just drop the whole subframe from the start and have a much easier time both in and out.

I took the car into the alignment shop a couple days ago and the guy asked if I had been jumping the car because the alignment was so bad I explained the clutch install and he understood.

I've drove 150 miles now, and haven't begun to power shift, but I've gotten into it a bit, the car feeels peppier, probably a combination of less slop from the bushing and a little less weight in the flywheel. The clutch feel is great, very happy so far. I'm excited to get it fully broken in and really get into it.

I ran my 12.9 passes with the Exedy stage 1 clutch. I've made several hard launches from 3500rpm and 4500rpm two-step and it has held up great giving me 1.7-1.9 60ft times with slicks. No slipping at all! You will really notice how good the clutch feels when you start beating on it. It can handle alot.

One potential MAJOR issue....

Great write up!

One potential MAJOR issue....

Quote:
I was working alone and when I tried tightening the flywheel bolts the engine was spinning, so I put a ratchet on the pulley on the other side of the motor and held it in place with a piece of a ratchet strap and pipe. When I turned from the other side it would butt up against the lower A-Arm and allow me to tighten the bolts
While I like this solution for working alone, I've done similar things from time to time on various repairs in my life, I think we need a "public service announcement"......

IMHO - I would just make a point to warn people not to even try this in reverse when removing the flywheel. While the torque spec on the crank bolt is much higher than the flywheel bolts, if the crank bolt is backed off even a tiny bit, it could cause the timing gears to slip creating catastrohpic engine failure.

There is no keyway on the Duratec crank and it relies on crank bolt torque 100% to maintain cam timing.

Otherwise it's a fantastic write up with great pics etc.

Great to hear! I will be having this installed on Tues! I have the FSWerks stage 2 turbo kit as well and my stock clutch doesnt like it when I really get on it. Right now, I have to ease into boost with like 30% throttle and then start putting my foot down. If I try to get on it hard, starts to slip like crazy. I also cant shift very hard or fast, sucks. Whats the break in? No hard driving for 500 miles? I am assuming I can still boost as long as I am not hard launching right?

Excellent point. Almost scary there is no keyway! After the flywheel was back on, I put the impact on the crank bolt and gave it a few bursts and it didnt move at all so I dont think it ever loosened up.

Exedy recommends 750 miles of non agressive driving. Can't comment on it handling your turbo power.

Long term driving impressions: I LOVE IT! The clutch grabs real low on the pedal travel and it grabs hard. It took some getting used to because there is very little slip, its more like an on-off switch, but I'm used to it now and can still drive as smooth as stock. WOT shifts from first to second are crazy, I almost have to come off the clutch slowly, I can't just dump it like I would when stock, because it grabs so hard it feels like it might rip the transmission out of the car.

The lightwieght flywheel and poly bushing are great too, there is noticeably more vibration in the car at idle but its very tolerable. Once your moving there is no noticeable difference in the car as far as vibration goes. This is still my daily driver and the clutch, flywheel and puly bushing are fine for daily driving purposes. The clutch pedal is much stiffer than stock, I sometimes drive about 45 miles in stop and go traffic and it gets a little old working the clutch, but I wouldn't change it if I were starting over. All in all I love the clutch, flywheel, poly bushing combination and would recomend it to anyone with a mild build and a heavy foot.

Are you supposed to resurface a new flywheel?
