Is this normal for a stock RB20 clutch?

[Gold Digger]

OK...so today, I went and took the clutch and flywheel off my engine. Low and behold, when I get the pressure plate off, I notice that clutch disk is stamped NISMO, as is the flywheel. I am pretty sure this isn't a stock setup, but can anyone one confirm for me.

I believe the part numbers were as such

Pressure plate. RS560Clutch disk. RS4--Flywheel RS521

Thanks

sounds simmilar to a clutch we pulled off of a friends car when we put the rb20 in his, its an uprated rb20 clutch but it isnt anything superfantastic...

put up some pics of it. If it was a really expensive Nismo Clutch set you would know cause the pressure plate would be like a copper toned red color. If so then you may have a Coppermix Clutch which can withstand like 480ps.

it wasn't that color. if it was a coppermix, i would have left it on. its just a nismo stamped daiken clutch, both logos are on the clutch disk. i have some pics, lemme see if i can find them...

Cool man, thanks. I am going to get pics this afternoon. I'm gonna head over to work on my engine in about an hour. Gonna try getting the intake mani off today...lol. Should be fun. Gonna be a hot sumbitch today.
