if i install an after market clutch do i need after market flywheel?
 

first of all i am new here, nevertheless would appreciate the advice.. so 3 weeks ago i installled a Sach's power clutch kit on my 87 supra n/a. Once installed, the clutch screeched horribly when pressed. drove it for about a day and the noise went away but now the clutch simply gets stuck down when pressed ... after consulting with friends they suggested it might be the fact that i used the original flywheel and thats what caused the clutch not to work.. your advise would be greatly appreciated ...and no im not a girl..my names alex..lol alice is my mk3..

male or female welcome aboard.
it is always a good idea to replace the flywheel when replacing the clutch or getting the old one resurfaced. Should only cost between 25 and 50 depending on local pricing. The idea is to have clean surface meet clean surface and prevent the above issues you are experiencing..
good luck and again, welcome.

edit.
If it was me I would just shell out for a new lightweight one. Preventing any "hot spots" from the resurfacing / cutting. but hey, 20 bucks is 20 bucks..

If when you press down on the clutch pedal you're getting noise, from my experence its and issue with the throwout bearing.

Did your clutch kit come with a new bearing?

I agree with green. If you have the tranny out at minimum resurface the flywheel. Cost me 45 bucks to do mine! Just as you would never re use an old clutch you should never re use an old flywheel surface. Lightweight flywheels are great but at a cost. Atleast $300 bucks for a cheapy, so if your goin for an all out performance engine or just want to squeeze the most out of the motor at any cost, then hell yea go with a light weight fidanza.

But if you are on a budget and just use it as a daily driver. Then resurface the oem flywheel. If it is within limits to do so. (the shop doing the work would kno the limits)

IMHO I don't notice a huge difference for the price of the aftermarket flywheel. So I use oem on my daily driver 1j in my Sig.... But on my full race build 7m I had, I used fidanza. but I was trying to squeeze every HP I could out of it!

This is true also. I hope you replaced both throwout and pilot bearing while you were in there!

too me it sounds like the clutch material is bonding to the glaze left on the original flywheel. if it wasnt resurfaced its possible for this to happen, seen and heard it first hand (damn nissan altima...) throwout bearin is possible as well, if you dont grease em up good they like to make noise. also if the T/O bearing isnt made for the clutch kit and its a high load presure plate, it will destroy the stock T/O bearing (first hand knowledge as well).

a lil touch on flywheels here too. lightweight flywheels arent always the way to go. personally, in an N/A car, esp. a heavy one like a mk3, a heavier flywheel is more preferable, as it helps the engine carry and maintain the tq load through the drivetrain. so in other words it would help if you were drifting. a lightweight flywheel i would only ever use for turbo apps, to help alleviate any boost-lag compounding effects. then u dont have to worry as much about carrying the tq load, cuz the turbo is over riding most of the effects of centrifugal effects.

sure with a lightweight flywheel ur n/a will rev quicker and maybe be a lil snappier, but the engine will be working harder in sustained heavy driving.

had a lightweight flywheel in my camaro, worst buy i did for it. i ended up swapping the 14# aftermarket one out for the stock 22# one, and got a whole lot more control out of it. just my .02 Cents!

didnt even look to see if his car was a na or not.. +1 for good advice
