since everyone on here owns an ITR...
who amongst you has bought a new OEM stock clutch replacement from all that racing around you do?

my question is....
Does the OEM ITR pressure plate have 'P5P' stamped on it or P72 or P73? I ask this because P5P is a prelude part number. I have a friend (shawn k) that bought a new PP from Mike K and it had P5P on it too. Dont' get me wrong, I'm not checking if Mike K sold my friend the wrong PP - cuz it worked fine - I just wanna know how many others have seen this P5P part number on their stock ITR PP....
(am i bit redundant? lol)

I've also encountered this part number being on a PP that my friend got with his B16B engine a while back. We were inspecting the engine, cracked the trans off, and noticed the pp had 'P5P' stamped on it also. He didnt' use it because he was starting putting new parts on it....but I just remembered that there was a P5P stamp on that B16B's PP also...

And if this PP is an actual prelude part, and Honda uses it on the ITR/CTR engine....I wonder what makes it better to use over, lets say, a GSR (P72) PP ?

thanks for any replies that help answer my boggling question

 

Actually, it's the disc that has the P5P stamping on it. The pressure plate has no markings. This is exact opposite of my stock GSR clutch I pulled out; that one had P72 on the PP and nothing on the disc.

 

I have an ITR clutch disk sitting right here on my desk, and it has no markings on it. The PP does have the "P5P" stamp on it though. I think the disk is the same on ITS/GSR and the PP is different, maybe the other way around. But the ITR PP is pretty strong, i had it in with a 6 puck disk and it worked fine.

 

sigh...no one seems to know for sure which part differs from the GSR, is it the pressure plate or the disc? And I wonder why my PP didnt have the P5P on it. Only the disc did. Oh well. I'm really not happy with this clutch, the feeling is so vague. Even my wife misses the stiffer GSR clutch.

 

You like the GSR clutch more? Thats strange, maybe you got the wrong one or something, cause the ITR clutch grabs WAY better than the GSR one. Maybe its because the GSR 1 was worn out, the pedal gets kindof stiffer. What dont you like about it?

 

The ITR disk should have less surface area (smaller diameter) than the GSR.

 

Can you explain why the Type-R disk would be smaller in diameter than compared to the GS-R disk? I would expect that they would both have the same diameter.

"Inquiring minds want to know!!!"

 

Im wondering the same thing. I have never seen a stock GSR disk, but it doesnt make much sense that a clutch that handles more HP than a GSR clutch(ITR) would be smaller.

 

The friction disc is the same for the GS/LS/GSR/ITR, the Pressure plate is the same on the GS/LS/GSR and the ITR pressure plate is different. If memeory serves me right.
