ej251, I think it's around 25lbs. All I know is that I think I gave the poor postal woman a hernia when I shipped out my old flywheel to someone...

yeah the stock one from an EJ25D that i tore down at school was 26lbs IIRC, i'm sure it's pretty close to that

Word, I guess it'll be a world of a difference going to 13.4lbs haha. Exedy stg 1 next week, still contemplating on doing timing belt while the motors out

I've been doing WRX clutches on almost a weekly basis here, all the EJ20 flywheels are 23lbs.

You should do the TB service with things out...it's really really easy that way...you can just hit the cam gear bolts with an impact...makes life enjoyable rather than having to mess around with tools to hold the gears...

That's what I have in mine. I like it a lot. The clutch is a lot heavier, if you will, but I like it that way. The flywheel takes a bit of getting used to, but it really suits my driving style better with the quicker drop in RPMs. There will be flywheel chatter when you let off the gas in gear, and sometimes when you engage the clutch from cruising speed, but you get used to it. It will also tend to surge a bit more at lower RPMs (ie: cruising slowly through parking lots), but again, the improvements outweigh the negative effects imo.
