clutch pump question - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

sup guys. can the clutch pump (the one near the pedal) be replaced with a bigger one (300zx maybe?) to make the pedal lighter? i have a nismo clutch and cylinder, and a sorta bad knee and i dont wanna put much stress on it...

any ideas?

sounds to me like you would need a smaller bore CMC. smaller bore pushed more fluid with less effort.

aga · 11-13-2013, 04:34 PM

any idea from which car it might fit or something? a friend of mine says he tried to put the 300zx one but it needed a lot of fabrication...

no a 300zx clutch master cyl is not really what you want.

You need to research and find a Smaller bore CMC (clutch master cyl)

a smaller bore will push more fluid with less resistance which makes it easier to press.

If you have a Nismo slave cylinder (at the tranny) and Nismo clutch & it doesn't feel light as hell, you are doing something wrong...

I run an OS-Giken twin plate with Nismo slave cyl and OEM 240SX master cyl and the pedal is very light.

I dunno. i had driven an R34 with a twin disc nismo and it was light as an oem one...

it actually became a lot harder when i installed a high pressure clutch line, but the shifting became much better.

its not stupidly hard, its a little hard, but like i said i got a bad knee...

mr greek man you must take care of your bad knee and eat several yummy gyros in large amounts to help the knee heal.

BTW, your build thread is fckin awesome!!!!

but seriously i would love a real greek gyro right now

aga · 11-15-2013, 09:03 AM

sleepyS14se · 11-15-2013, 09:07 AM
