I too have an ap1 flywheel on my ap2. My flywheel came marked for an '02 S and weighed exactly 13.5 lbs. on my friends small scare at his motorcycle shop. I figure it would have to be accurate since its in a professional business and they have to weigh random parts when they build race bikes and the owners want to know the weight differences.

Biggest differences I noticed:

1. Car became peppier in the midrange

2. Car does not bog anymore on accelerations from a dead stop when the a/c is cranked on hot days.

3. I revved my car to 6k and watched the rpms drop then revved my friends' car to 6k and watched the revs drop several times, minutes apart. My friends' car is very similar to mine...Same year, similar mods(intake & exhaust), even the same color. But his still has to Ap2 flywheel in it. Mine dropped to the 1k idle when his was just passing the 2k rpms still dropping.

Hope that helps out

Ok, slight chance I might have sent the OP the wrong flywheel, a B series flywheel. If that is the case I accept the fact that I am a total jackass and give you all permission to point and laugh at me!


What I need one of you guys to do with an AP1 flywheel is measure the outside diameter of the friction disc area and the flywheel disc itself as pictured...




The one I have here at home has the flywheel teeth chamfered on engine side as apposed to on the driver side like the one I sent the OP. Which that in itself leads me to believe I sent the wrong piece since on the S2k the starter is on the engine side and on the B series motor it is on the tranny side.


So after this is confirmed I will ship the OP the right flywheel asap!

I just measured those two points on the flywheel you sent me and got 10.25" and 8.75" for reference.

The flywheel I have is 10-1/4" and 8-3/8"


Now someone chime in so I can make sure Steven has/gets the correct flywheel!

^How much does it weigh? Also, the clutch and flywheel pic you posted shows a flywheel with a ring gear that is flush with the engine side and not the friction side, which seems to coincide with the other AP1 flywheels here.

Measure here: 259,5 mm (10,216")
And here: 214,0 mm (8,425")

Got the right flywheel today and everything is resolved. Thanks to 300sx for being a good guy and making things right!

No problem man!

And again sorry for the mixup! But on the bright side it made for an interesting thread on here! lol
