Hi, I've recently gone through the same issue. My new RPS clutch goes in on Wednesday at Greenlight Honda here in San Diego. I'm not sure if you want a stock or aftermarket clutch, but I chose to go with aftermarket for my 1999 NSX-T. I got a lot of feedback on the issue and found out there things:
1. The best price I could find on 97+ OEM dual mass clutch assembly with flywheel was around $2050. I think it was about $1200 for the OEM assembly for your car.
2. South Coast Acura (Costa Mesa) would repair the clutch without changing the flywheel for $1900 parts and labor. Plus $2500 more if it needed the new flywheel. After speaking with a few NSX mechanics they recommended replacing the entire assembly.
3. From Chris at Science of Speed - The RPS clutch is similar to the Comptech Stage I & II clutches but instead of a single disk is uses a billet style 4 piece disk that prevents warping. Check it out on the SOS website. I chose to get this clutch from him it was $1824 for the parts with shipping to San Diego.
4. Autowave in Huntington Beach (distributor for RPS clutches) quoted $2475 for parts and labor.
5. NSX prime members are the best, as they will always take there time to provide you as much info as they can to make sure you make an informed decision.
I also spoke with Anytime (John) who has the RPS clutch in his CTSC NSX. He had good things to say about the clutch (thankfully since I had already purchased it when I called him) and said it had less petal pressure than the Comptech options, but make no mistake it will have more petal pressure than an OEM clutch.
The OEM parts are a cheaper for your car than mine by about $1K so you may chose to go with the OEM option. But I'm really excited about my new RPS clutch. I'll send you an update once it's in.
