Hi Guys,
I've done the search thing and read about the various aftermarket clutches available for our NSX's, BUT nearly all of them are for 91-96, 3ltr, 5spd cars.
I have a '97 built 3.2 6 spd (actually a JDM Type-S) and the clutch is on the way out. :frown:
Symptoms are....
It's overly heavy (all the time )and doesn't completely disengage every time. The latter feature is only evident at rest so that sometimes it is reluctant to go into any gear, you can feel the car try to move (nudge froward or backward) as you gently try all gears until you find one it will "fall" into, after which 1st or Reverse become easily available and once rolling all is well. Classic clutch "drag"?
My requirements....
Essentially enthusiastic road use. The car is not a daily driver so when I do use it it's because the weather/occassion lend themselves to a breaking out the NSX and invariably a spirited drive ensues. Any of you with experience of British weather will know that these opportunities can be few and far between.
I may do the occasional track day but don't need race car levels of clutch bite and/or heaviness of pedal action. Ease of use and durabilty are my priorites.
Observations & Questions...
Factory/OEM clutch kits come with a new flywheel. Why?
Most aftermarket clutch kits also come with or recommend new flywheels. Again why?
What happens to the flywheel that means it wears at the same rate as the clutch? I guess it must the central bearing/joint/thingy! that connects the dual "masses" of the standard flywheel?
Anyone replaced just the release bearing, friction and pressure plates? Can these even be purchased separately ie without the flywheel?
I'm fairly proficient mechanically and have replaced plenty of clutches in my cars over the years. I've never HAD to replace the flywheel along with the clutch before. If it wasn't scored/warped/worn/broken it was fine.
My previous Porsche Carrera (993) had a quite similar dual mass flywheel to my NSX and this didn't need a new flywheel with a clutch replacement. Why is the NSX differant?
In fact IF the stock 993 dual mass flywheel was replaced with the 993RS specification item (a popular modification in the Carrera 993 world) the engine management would struggle to cope with the lighter rotational mass and the cars often stall as the revs decay. Assuming the NSX PGM-FI is superior to the Bosch DME fitted to 993's this latter feature won't be a problem. :smile:
I was planning the clutch replacement as a winter project and thanks to the Workshop manual available here on Prime, and the excellent DIY install thread by VBNSX I'm reasonably confident I will be able to do it, hwoever I want to determine what parts to order.
I'm leaning towards the RPS clutch, any comments?
Sorry for the long post but hopefully it make my question clear.
Cheers
