Hello there,
I have a little specific questions. I have a 350z vq35de rev-up engine and I bought racing clutch with a dual disc. It's from Xtreme Performance clutch, but it seems like my clutch pump (if its called like that) and my gearbox pump (also don't know if it's called that way) are too weak and they can not open the clutch can not open completely. So when I press the clutch it starts to make a scraping noise, and also when I want to change gears, I can't shift properly. I tought that I putted it wrong, cuz I already broke it once, but when I bought the repair kit, it started to make the same scraping noise. So I want an advice. Should I buy stronger pumps, or I should buy a new clutch?
The engine is vq35de rev-up with a nismo gearbox.

 

Sounds like something is wrong with the hydraulics. It could be due to improper bleeding causing air in the line or the "pumps" called the master and/or slave cylinder are malfunctioning. Possibly improper adjustment of the push rod or clevis from the clutch to the master cylinder. It could even be improper clutch install. Did you replace the throw out bearing? Clutch fork? Too much/not enough fluid?

Sounds like you would be better off taking it somewhere.
