    I didn't know these cars had a clutch delay valve...interesting. Let us know how it feels. Looks like a stiff sum bitch.

    Damn, life is easier with a lift. Looks good, definitely want to hear how it holds.

    I think since 02 they have a spring/pressure operated bleeder orifice plate in the Slave - it slows the engagement of the clutch from about 80% engaged to 100% over a delayed period of time. The Exedy instructions PDF gave a light (I mean glossy like a mofo) description of the removal of the delay valve. Nasioc has a huge process to basically take all flow control out of the system, I just did the Slave delay valve, which, after it was all done, was damn easy. I also did the goodrich braided clutch line...forgot that part.

    I'll drop some results soon, I'm going to do the SD swap, and then some ID1000's and a Fuel pump for some summertime DD fun.

    I also picked up a group-n Trans mount, and a perrin pitch stop, with a Kartboy Shifter bushing kit (front and rear) and some diff bushing inserts...

    Looking good man!

    It'll be a little stiff, but its worlds better than the Tilton and others out there plus you can drive it in traffic.

    Drove it a bit lastnight to get the feel for it.

    First - My poor stocker - for about the last 5 or 6 months, it's had issues holding up in 5th and 6th under "heavy" throttle....

    This TD grabs and won't let go - it's like I got a new tune or something. The peddle pressure is about 15% more than stock - lightly noticeable, but not like a XT from ACT, even lighter than the HD from ACT by a little.

    Noise - it's pretty quiet at idle, but blip it and you get the tin can full of rocks sound everyone loves...

    All in all, sort of a PITA to install, works fantastic, not hard to drive in traffic, just different.

    I like it, and plan to DD it. I will post up another review in a few months.
