Hello guys I’m new to this forum, I’m having some trouble choosing the correct clutch for my car, I currently own a 06 civic si k20/k24 swapped, with an rsx type s transmission, my clutch went out the other day, can I still use an oem clutch? Or do I have to upgrade to a more high performance clutch?

welcome to the forum.

When online sellers advertise for clutch sales they just list this as "Kseries". They are interchangeable clutches however certain ones require certain flywheels to work with each application best. Normally the advertisement is clear. The flywheels are interchangeable.

You can use an aftermarket clutch or oem clutch. With your power level a Exedy stage 1 will handle the K24 until it makes 200wTQ, then will need a stage 2. You can upgrade to whatever you want depending on how much of a stiff clutch or softer clutch you want.

You should not be re-using oem flywheel bolts. If you do the work yourself, you need to buy a ring gear holder fo the flywheel so the crankshaft does not move and nor will your timing assembly.

When doing a clutch change, you need to replace the clutch release bearing PN# 22810-PPT-003. Replace the release fork setting spring PN# 22835-P0S-000. INspect the backside of the clutch release fork where they slave cylinder piston pushes against it. It is supposed to have high temp grease (Moly 77) there. when the grease runs dry the piston the fork thins from friction and starts to flex.

Thanks for tips I really appreciate it, question though, when I bought the car from the guy he told me the head was built as in it had upgraded cams and bigger injectors etc, would a stock clutch still handle that power? Or would I still need to buy a stage 2? I’m asking because I’m really impatient and I would rather buy the oem one from AutoZone rather than waiting a week for a stage 2 to be delivered to me. I live in tbe Virgin Islands so things take kind of a while to get shipped here

Even M62 eaton supercharged Ks, both k20 and k24 "only" run on OEM and stage 1 clutches. I'd stick to full circle organic clutches unless this is either a big power/torque car with a huge supercharger or turbocharger into the 4xx power/torque regions or you're doing serious drag strip work requiring dumping clutches and spinning wheels several times a day.
Anything further becomes a nuisance in a daily driver with their on/off characteristic and low life expectancy if not properly run in.

The Competition Clutch stage four clutch has been the benchmark for higher horsepower turbocharged and supercharged applications for the K-series motor because of price and drivability. We recommend going with this level of clutch when in the 400-500whp range although we have tested it to hold even more horsepower.

We recommend
welcome to the forum.

I am curious when you say "we recommend" - what do you mean by "we"?

are you a vendor or seller somewhere in the world and where are you located?
