Default 2004 AP1 (F20c2) flywheel

Hey guys,

I own a UK spec 2004 AP1 with F20c (facelift model)
VIN says AP1
The UK spec / euro spec / JDM model continued to use the F20c after the facelift year, that is 2004.

My question is, which flywheel do i have? the 14lbs or the heavier one 22lbs?
I do have all the revisions of the ap2 model..like the clutch delay valve (revised clutch slave cylinder)

Does any of you guys know? or do i have to split it apart and measure the weight!? (which I am going to do when i get my clutch done)
The reason I am asking is because I am going to get my clutch changed soon and in case I have the heavier flywheel I am going to replace it with an aftermarket one. In case I do have the 14lbs one I am goingto stick with that one.

Thanks in advance!

I'm going to guess and say the AP1 14lbs. The 2.2L got the heavier FW partially due to the lower redline.

Unless someone knows for 100% sure, I would break up the job in between just in case, as you'll need to machine the flywheel regardless. So if it's the 22lbs one, then source a FW quickly.

iDomN8U, that seems to be the plan ;p

I have an ACT prolite (8,8lbs) ready to be installed in case I have the 22lbs one..

I have a friend that recently changed his clutch and has one sitting in his garage..He said he will measure it for me..So I will know beforehand
Either way I will let you know anyways.

You have the AP1 flywheel, like I did (2008 European DBW).
