Default Getting lightweight flywheel, need to replace disc/bearings?

My engine blew up last year at the race track I bought a salvaged donor car with 22k miles on it to swap both engine and tranny. I am planning to buy a lightweight flywheel this week to help with heel to shifting.

Since the clutch has 22k miles, and worked before I dismantled it, I figure I could just swap the flywheel as long as the condition of the disc, pressure plate, release bearing is in good condition. I normally would opt to replace the disc and bearing for preventative maintenance but the bearing is 160 and the disc is quite a bit too. See my struggle?

You can buy the Honda bearings from Nachi themselves for a good deal less. If the clutch disk is in good shape with plenty of meat left re-use it with confidence.

p# is Nachi BRG105

You the man! I did this with my wheel bearings by finding the timken product number. Know of a reputable source other than ebay to buy the nachi bearing?

Is this an ap1 or ap2? If its the clutch buzz ap1 disk, you'll want to swap disk. If its the updated disk, and its still good, I would run it.

You can find photos online of old and new disk design, and visually see which one you have.

It's an ap2 motor so it should be fine. I am pulling it out this weekend. Besides enay, are there other sources to find the nachi bearing?

So you're using the disk of a donor car, not your own disk that had 22k on it. I'd swap it out.

I am using the donor engine, transmission, disc, pressure plate. All of which has 22k miles. The only thing I am replacing is the flywheel and throw out bearing per suggestion above. I will not be using the blown engines parts.
