Clutch question

[smoker]

I need some help again , I think my clutch might be slipping as I felt the revs surge when I put my foot down on the A1 last ( I hope it might be wheelspin but I think its unlikely as i was in 5th gear doing 80 mph )
I'm on a tight budget so I used my old silvia pressure plate and a new 9" friction plate from a 200sx from Nissan. I'm thinking old clutch cover wont be strong enough , does anyone know if these should work together ok. Cheers

They do work together but wont hold as much as a full s13 clutch. What sort of power is at your flywheel?

[datdrift]

i ran with a s13 exedy heavy duty clutch plate, with a standard cover for a bit as the cover i was intending to use was for a ka24 and dident quite line up on the dowels, it did slip every now and then but only when drifting and putting lots of strain on it, but now i'm using a s13 cover as well and it hasent slipped once yet

You think you're bad - I've just fitted a brand new clutch to my s12, and it slips like fcuk every time i floor it in 1st & 2nd. I'm a mechanic and fit clutches every day and i am puzzled.......

[adzs12]

What clutch have you fitted?

[Dez]

Standard s12 clutch kit. I was going to fit a race clutch but i want to put money into getting the bodywork sorted. The car was barely drivable so i decide to fit the standard one for the moment. Still can't understand whats wrong though. If i floor it, it's fine til about 3000rpm then - nothing. i have to back of the power to regain drive

[adzs12]

Is the car standard?

[Dez]

yeah as far i know. No obvious engine mods. Standard t2 turbo

[adzs12]

Hmm strange mate only thing i can think of is there grease or something on the friction plate but then again your a mechanic so im sure you would have made sure it was all clean and dry.

[Dez]

yeah i definately didn't make mistake. You can even tell by the sound of it when it slips that it's bone dry. It's as though it can't take the power of the engine - but it's a standard engine - standard clutch should be fine.
I think i'll just pull it out again and use it to knock the sh*t out of the guy in my local motor factors.
Thanks for your help anyway mate
