my car: SS--->5 speed
I am facing a dilemma to chose the best clutch+flywheel comb.
my car will pretty much stay I/H/E+NA setup. maximum power will be between 200-210WHP.
maybe i will go for JRSC. i am not sure now.
by the way. can you guys give me suggestions about clutch+flywheel comb.
plus, is there any final gear i can get?
sould i do the ECU adjusting in the same time? Hondata, v-afc?

Best clutch and flywheel combo is the Tilton clutch. Cost is very high, $1300.

Other than that, a Fidanza flywheel is the best, IMO. That's what I have, and I'm also searching for a good clutch. I've owned an Exedy Cerametallic, and it's an excellent clutch. I might just go with that one again, but I'm also looking at Competition Clutch, Bully Clutch, RPS, and Spec. I just haven't decided.

To make 200 WHP, you'll need some type of fuel management, so if you're going to do it all at once, I'd suggest at least a VAFC. If you can afford the tuning costs, a Hondata or EMS would be ideal.

As for final drives, Jamie Houseman of Houseman Autosports can do custom final drives, but the cost is close to $1750. ProDrive offers a final drive for the H22 tranny for $1250. E-mail me if you're interested in discussing the ProDrive final drive (I can't discuss it here ).

I think tilton only makes twin plates for the H series motors. The single plate is only for the B series.

ACT HDSS + Fidanza flywheel is sufficient for anything under 200whp but if you are going to go past 200whp then upgrade to ACT XTSS clutch just to be safe!

Twin plate. I'm not aware of any single plate clutches that Tilton makes for the H22. Even their B series single plate clutches are close to $1000.

One other thing to keep in mind is the Tilton clutches are not sprung, so they aren't the best choice for a daily driver.

Billy knows more about the H22 than I do, but I am going to respectfully disagree here.

There is very little information online about selecting a flywheel. I'm not going to get into a big debate about aluminum or chromoly, but based on physical construction, the ACT Xact series flywheels are the only thing better than the JUN design. Both are one-piece chromoly. I believe that the Xact flywheels are superior to the Fidanza design, based on mass concentration, failure points, and surface finish.

There is a lot more information about clutches in general. There are only a few clutch surfaces that are effective, and it makes the most sense to choose a clutch starting from there. The three areas are organic, ceramic/metallic, and synthetic fabric. Organic is not the best choice IMHO. It used to be the friction material of choice for the street, but the fabrics are superior now. The ceramic/metallic clutches are great for drag racing or hardcore road racing. They have fast lockup characteristics, and can handle the largest torque values of any material. The fabrics are usually Kevlar or Carbon. There are several clutch vendors using Kevlar, but there is only 2 major suppliers in the US that make the friction material. Therefore, the biggest selection criteria would be construction quality rather than surface. Tilton basically has a lock on quality carbon clutches, no one else really comes close. The fabrics are an excellent blend of streetability and torque capacity. I believe they are truly ideal for most users of the online community.

I personally bought an Action Clutch stage 1KS which holds 240 ft-lbs (about 350 bhp). I haven't installed it yet, but it is supposed to be smoother than stock, and Kevlar is real easy on the flywheel. The beautiful part about Kevlar is that it lasts almost forever. It is common for Kevlar to last 300k miles before the lining goes!

One excellent place to learn more about clutch construction is to read Rocket's Clutch 101 guide.
