If you're bothered by the lag between pedal and engine response then yeah, flywheel won't help, if you're bothered by how long it takes for the engine to spin up that's a flywheel change. Downside of the lighter flywheel loses revs more quickly as well potentially making upshifts awkward.
I think it just commands more throttle input. If you spin the engine properly to match your drive-line / desired response, a lighter flywheel is very rewarding.

I find stock rewarding as-is

I guess it depends what you're doing with the car. There's no blanket answer. My goal is circuit performance and for that a light flywheel is fantastic especially with the quick inputs

That's fair, I do mostly autox and aside from the launch and 2-4 shifts per run there's much more time and satisfaction to be gained elsewhere.



Plus rulesets keep a lot of things stock :P

I tried all the suggested fixes short of actually doing the clutch swap. None of them actually fixed the engagement point like I hoped, but they did make the pedal feel a little bit better.

I have decided to go ahead and do the clutch and light flywheel swap, I will likely do the MTEC shift springs while im in there.

My question is, is there a tail shaft/output plug for this trans? I just recently <10k miles ago just changed the fluid to Motul, and I would like to not have to spend another $60 on fluid. Or can someone chime in with the diameter of that seal?

Drain it into a clean bucket. Strain it and pour it back in.

I like you, No idea why that didn't come to my mind.

I even have one of the motul bottles left, I can use that to put it back in the trans.

Throw a bit of cheesecloth between the containers when you transfer it and it will filter out any contaminates that may be there. Don't forget to wipe down the magnetic drain plug as soon as you pull it.

Agreed, cheese cloth is a better idea than the metal strainer in my funnel. I hope not much has collected on that magnet in just 10k miles, I cleaned it when I pulled the original.

Be sure to change your throwout bearing when you replace the clutch. Mine totally exploded a little over 60k miles. I think Toyota has released an updated TOB that's supposed to fix the issue.

The clutch kit comes with one, so that should be covered.

I don't know if the kit comes with a new pilot though, I am not sure how the original pilots are holding up.

Mine has started singing the song of it's people. Apparently it's people are Banshees.

In all the failure threads I don't recall ever once seeing an issue with the pilot.

@Gloonge How are you liking your new clutch setup? How's the daily drive-ability, especially with the lighter flywheel?
