Hello,

I am new to the forum and finally own an S2000. I recently purchased a sweet 04 with 43000 miles. The clutch is slipping for approximately 2 seconds in first and second gear while in VTECH. Is there any type of adjustment or am I going to have to change the clutch, pressure plate, etc?

Thanks in advance for your help.

-- the s2000 has a "clutch delay valve" that steps in when you wind it up too quickly, or severely...it lasts moment or 2....and is meant to save your drive train from self destructing - i've learned to be smoother on throttle in lower gears, but 4th to 5th, and 5th to 6th at red line will cause it to kick in as well

is this on all models or just the ap2 models

the CDV is only on the AP2.

Lighter flywheel, heavier duty PP, and '03 slave cylinder FTW!

Man I just learned about this recently, gonna pull the cdv before i put the car back on the road. Once I need a new clutch I'll be going with an ap1 flywheel with an act pressure plate.

Just remember, the heavier flywheel helps with power - increased rotational weight at the crank means more "torque", and easier to manage power since the rpms change slower. Light flywheel = easier to get the rpms up, easier to loose inertia on shifts and climbing, and more power needed for cruising. Heavy flywheel = more energy to get them up to speed, but better able to maintain speed during shifts and climbing, and less power needed for cruising. Heavier flywheels store more power so you loose less between shifts, lighter flywheels allow you to get the power to the wheels more easily.

Imo sticking with the AP2 flywheel and adding the ACT pp is a good way to go for street use, highway cruising, and for a smoother driving experience, but a lighter flywheel will give you more of a go kart feeling if you want it, or are tracking the car.

Heavier flywheel just gives you more inertial torque to carry you through the interim when you depress the clutch and free roll until you release clutch again in a new gear. Lighter flywheel allows you (and as a consequence requires you to) shift faster, whereas the heavier flywheel is more forgiving yet takes longer (relatively) to shift and to climb or decline through the gears. Cruising with lighter flywheel is only slightly if any different than with the heavier flywheel, in that when you take your foot off the gas in gear you decelerate more quickly with the lighter flywheel, which is advantageous on the track or in traffic.
