I have a 1997 gst with intake exhaust. I'm planning on getting a new clutch and flywheel as soon as i get taxes back. also i'm planning on putting in a evo 16g with fmic as well in spring. does anyone have any suggestions on a good clutch and flywheel set up. Also any decent places to get a good price on on. except on ebay. i refuse to buy anything off them. have got to many things that dont fit.
thanks
thanks

ACT on the clutch. They're plenty of debate on those. The stock flywheel resurfaced is fine, no need for an aftermarket flywheel imo.

You just opened a huge can of worms. Of everything I have researched, this is one of the most uncertain.
Clutches: First off, I would suggest a street a street disk. ACT makes excellent clutches. The 2100 should do you fine on a evo3 16g, but a 2600 would be just fine too, and when you want a bigger turbo, it will probably handle that better. I personally am going to go SBR for a clutch. SBR is a good trusted shop and I would buy any of their shit. The ACT 2100 kit is $350 and the ACT 2600 is $440 while the SBR 3500 clutch has less pedal pressure than the 2600, but more clamping force for $380. I suppose there are other good brands too, but I'd stick to these two.
Flywheels: Heres where theres an arguement. The stock flywheel much heavier than any lightweight ones, 19lbs IIRC, so when it gets turning it takes much more to stop it. That extra 7-11 lbs of rotating mass keeps the engine revs up and thus power to the wheels so you get better launches and 60' times. The other end to that arguement is that it takes more horsepower to keep that heavy ass flywheel spinning and the lighter ones free up some power and rev quicker. I have read about this lots and I have asked many knowledgable people and I have come up with plenty of answers from each side. That is one thing I definately plan on testing, stock flywheel to lightweight. Probably late this summer or next summer I'll check into that. Until I (or someone else) actually tests it out, its up in the air and your call.

My ACT clutch broke, one of the springs came out of it. This is a known problem with act clutches. I was forced to buy another act clutch (money constraints cause i already had a act pp) I will never buy from act again. If you have the money I'd go with a lghweight flywheel.

Think about it guys, he's FWD. Why does he want to rev quicker? He would just spin even more...

Well if the heavier flywheel creates more torque (as some claim) wouldn't that create the same problem? If not worse.

depends on where you are in the powerband, gobs of torque up high is great, But remember, max torque is usually right at where the turbo first spools fully. This is the point most likely to wheelspin in most applications.

Yeah i see what you mean. I still like the light weight flywheel, but i'm also awd so i don't have to worry about traction (yet :naughty: )

I'm AWD and running a Fidanza aluminum flywheel and an ACT 2600# clutch with no complaints.
