clutch problems

[514nissan240sx]

hello everyone. i have a 1996 nissan 240 with a silvia conversion it is a ka-t. i am having a huge problem with clutches. my car makes 514 hp on 21 psi and 480 fpt. my problem is slipping when i shift. i have had a act 2600 in it and that lasted maby 3k miles and if never held a good shift it looks like im lookin to need a twin disk any other ideas? i have been threw 2 clutches so far. thanks for the info

make sure the master and slave cylinders are not malfunctioning. If those are alright i would sugest getting an exedy twin disk.

OK ... Plain and Simple... Single is only good for about 400 hp... Twin Plates are good to about 600-800 depending, and 700+ should be Triple.

I have an OS Giken STR... its a Sprung type so its good for DD and Street-able, but can handle track abuse. If you want something more aggressive, go Un-Sprung.
I have the same OS Giken STR on my EVO9MR (un-sprung) and it takes allot of abuse.

The only complaint I have about Un-Sprung is you will need to change how you drive, and Heal/Toe on every Downshift... when the clutch is cold it will chatter and when being used allot (traffic) it will bark, scream, and embarrass you like your car is falling apart.

Other then that... fuck-em if they don't know power when they hear it!!!

you need a clutch with more holding power. plain and simple. also make sure that your master and slave are working properly.

I think the only company that makes a twin disk for a KA is competition clutch.. i heard it's good for over 800hp (I dont remember seeing how much torque...)
