All light weight flywheel newbie threads are merged here.

I'm looking for my car to be very fast at lower speeds; my main goal is very fast acceleration. Will a lightweight flywheel be beneficial to this? Or should I just save up all my money and drop a turbo on my 84k engine :)
 
Ok sorry just to make sure this is what i need:

Mechanical Catalog - 1996 - Mitsubishi - Eclipse
Front drive axle, Drive axles, Differential, Axle seals, AXLE SEALS, Eclipse, 2.0L, w/Turbo, 2WD (2)----$8.40 for both

Mechanical Catalog - 1996 - Mitsubishi - Eclipse
Engine, Crankshaft and bearings, Rear main seal, REAR MAIN SEAL, Eclipse, w/Turbo - 2.0L - 2.0L ---$13.68

That should be good right? Just dont want to buy the wrong thing.
 
Being that it's a 96 and you probably don't know if or when they were replaced....I would say yes, replace both.

Before you get to wound up on the clutch job, check your fluid levels. Check the carpet behind the clutch pedal. Especially behind the carpet as that's the first sign of the clutch master cylinder going out. And check for any fluid leaks at the front of the tranny around the front to rear cross member as that's the slave cylinder location. That might be your whole issue if it was fine and then over a few days or a week it started to take a dump and not go into gear.

Yes and yes. Those are the 3 seals needed.
 
Ok thanks alot i will check that, but need to replace tob so i want to get a good clutch and flywheel no matter what.

Do you by chance know if it's true with the fadanza or maybe all lightweight flywheels if at slow creeping speeds the car tends to stall out? I have heard that from a few people.

And also would the act 2600 be over kill for daily driving? I want some resistance when i to push the clutch in but not alot. I dont like the super soft feel clutch's. Thats what i have now.
 
Yes, that's why in post #4 I mentioned that for a DD it'll take a little getting used to. The lightened flywheel doesn't have enough mass and stalls easier, I personally don't care for it myself, but you can get used to it over time if you just have to have it.

A better choice if you're concerned might be the ACT streetlight flywheel. It's not quite as light as the Fidanza (8-9lbs), but at roughly 12 lbs it works nicely, plus it's not aluminum and not as easy to stall in traffic.

I run the ACT 2100, ACT streetlight FW, SBR LSD inserts in mine and think it's a great combination (for me).

The 2100 is really no difference to stock as far as "feel" goes. The 2600 is not much more expensive than the 2100, and you will "feel" the difference. Either way, I would recommend removing the "clutch safety start" wire so you don't have to have the clutch depressed to start the car. It's not proven, but some claim that having the clutch depressed during starting accelerates thrust bearing wear as there's no oil pressure during startup. Your call.
 
Ok thanks alot think i will probably go with the act streetlight then. That is still light enough to notice a good difference in revs climbing i'm assuming? Never used a lightweight flywheel before so dont know what to expect.
 
Ok great thats just what i want! Thanks alot for your help i really appreciate it. Hopefully this will fix everything and i will be able to drive my car again(been a month and a half since i have and only drove it 5 days!) I'll post back about it after getting the clutch job.
 
Yeah, I've been running the Fidanza flywheel/ACT 2100 combo for the past three years. It's been a great little set-up. And it recently held 400HP and 350 ft/lbs on the dyno for me, after three years of abuse.

I just pulled the clutch and flywheel off two days ago, and all is well. The clutch still has life left, and will be going in my buddy's 1G.
 
i have a fidanza 8lbs aluminum flywheel but its not installed yet, will let you know how it turns out because its going in nxt week with my new engine. By the way how much power/torque/ abuse can a 2600 take. I was thinking of that or a 2900 but I thought a 29 might be overkill ( I only have a fwd ) and I planned on getting upgraded racing tranny with lsd in the future. But my goal was like 400whp so I dont know if I will need something so drastic. ( But I like having extra insurance to that it will hold to everything I through at it and I wont have to ever go back in there again )

Oh and another quick random question by the way, how much power/ torque does the stock clutch hold up to ? ? ?

Do you have any problems with the car wanting to stall out with due to such a light flywheel? Is it hard to drive it in stop and go traffic for you? I am not ever taking it to the track or anything so only dd. Was gonna get the fadanza but seems like it might be too light for daily driving. You experience any problems with it?
 
I run that combo and sometimes it seems to give me troubles in traffic. If i throw the car in neutral from high rpms it will want to stall everyonce in a while. Like stated before it really just takes a little getting used to.:thumb:
 
I've got a Fidanza alum. f-wheel/ACT 2100 pp/Horsepowerfreaks disc http://www.horsepowerfreaks.com/pri...s-Flywheels/Clutches/part/Bronze_-_Mitsubishi combo in my DD, and I've only killed the motor once since the install, three weeks ago. So the answer is yes, that combo works well, you will love throttle blip (heel & toe) downshifting. Don't forget the longer f-wheel bolt/stud kit, for aluminium flywheels, from RRE.

I'm not sure of the torque rating on the stock clutch, but I did lose mine while maxing out my T-25 (back in the day), so how ever much TQ that was. My stock clutch didn't live long at all after I started increasing torque and power with modifications.
 
I changed mine 'cause after about 5 laps (track day) it would slip under power. I've only got a small 16g, and at the track I was only running 11 psi. Imagine my shock when I saw my (stock) clutch was MINT! Doesn't take much, apparently.

That stud kit isnt required even though some will say its recommended.
I didnt get one, and another dsm wiseman didnt use it, its 45 dollars of insurance i guess but Its not nessecary.

I decided to go with the ACT setup. The act 2100 clutch and then the ACT xact streetlight flywheel. Do i need to get some bolt setup for this one also? Or was that a Fadanza thing?

I also got a new rear main seal, axle seals, new ss clutch line. Would an extended clutch rod be a good purchase as well? Or anything else a good thing to get while i'm in there?

The longer bolts mentioned are for aluminum flywheels as they're a bit thicker than steel and you have to go longer for proper thread engagement (ACT Streetlite = NOT REQUIRED).

The extended clutch rod is something that is also NOT REQUIRED, especially using one manufacturer for your clutch components. Sometimes they're required with mixing and matching or using "used" components if the step hight is not acurate.....bandaid fix IMO.
 
i have a 9 pound ssg flywheel for my 2g awd, and it needs a new plate bad, but i cannot find any place that stocks them, and when i got to there site it only says a replacement it 50, i do not see anything on the site thath directs me to custumer service or where to buy, if any one has any info pleasee let me know i need help bad with this, if not then i guess i will be forced to buy another flywheel.
 
i did some searching and found a vendor who can " get them" so i asked him if he could get me a new friction plate and i am waiting for a reponse.
