Time to buy a new clutch for my build as i need to get it balanced with my crank. Aiming for mid to low 500's at the wheels.

Opting for the OS TS2CD, item was originally in the vehicle and felt like OEM item (only had 350hp though). Can only find 1 site with its rating and it says up to 600hp. Have also been recommended the excedy hyper multi (twin plate), or the excedy hyper compe-d.

Im after a clutch feel that wont make my car a bastard of a thing to drive. The OS giken clutch that was originally in the vehicle felt like the OEM item and is why im opting for it this time too.

Your opinions pleas?

Yeah they are good. Being a "c" means it has the larger diameter plates so its power rating will be higher than the b type os twins. Os make great clutches. I've personally owned probably 5 or 6 in various cars all twins or triples and whilst they can be noisy and sometimes a bit grabby they are super reliable and in my experience their power ratings are fairly conservative. So if you'll have 500hp(or did you mean kw?) at the wheels then a 600ps rated os giken should be fine. Personally though if it were my car with a genuine 500hp atw and it was going to be track driven I'd consider a triple as with more surface area they deal with the power and heat really well and hardly wear at all if driven properly. But if you already have the twin and it's in good shape just use that.

Cheers for that Mr Baron.

Ended up ordering a TS2CD the other night off RHD for a pretty cheap price. Had to order another one as this one was KECK. Needed to get balanced with the crank so i kinda needed ASAP. Car will probly not see many (if any) track days. Was really happy with the way it performed before my engine detonated, just wasnt too sure if it could handle my new aimed power figures.

i'm sure you'll be happy mate. they're a good thing. should have just bought the rebuild kit though providing flywheel and cover were ok? comes with new plates, new sandwhich plate and new top plate/pressure plate and bolts. you just retain the original diaphragm, carrier and flywheel. cost around $1000-$1500 depending on model.

    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
