I've been trying to research this all over the net, and I'm getting a lot of mixed feelings from posters and commenters about their clutch kit brands and stages, and flywheel brands and weight.

I wanted to see what you guys recommended for a NA 2000 Civic Si with around 160 ft/lb of torque and 190 hp?

I currently use the car for commuting to work (95% highway) and typically don't pull hard unless I'm in the mood or the 'stang next to me wants some.

I also may end up throwing a turbo on it later down the line, but probably not for a while.

Thanks for the input!

 

i like the Competition Clutch line, there a good price, and there solid. Used it on my turbo s2000 and it held the near 400 horses it was putting down with there 6 puck. All your gonna need though is a nice street clutch like this

Competition Clutch 99-00 Civic Si, 94-97 Del Sol DOHC VTEC.

STAGE 1 - Gravity Series 2400 Clutch Kit is the economical solution for moderately increased cars and/or stock cars driven in an aggressive manner. This clutch system will safely guarantee 40-50% increase in torque capacity and still deliver extended life.

 

The brand name doesn't really matter as long as it's not a no-name brand. Exedy, centerforce, competition, etc... ( I believe Exedy makes OEM honda clutches).

I'd just go with whatever their organic street clutch setup is. Better wear and holding capacity than stock, but still perfectly fine for the daily drive.

at 'stang comment :chuckles:

 

Ahh, I hadn't seen the Competition brand yet, just a lot of Exedy and ACT. That price is definitely more reasonable than most of the clutch kits I've been seeing. That site is confusing though...the Stage II is more expensive than the Stage III and IV's?

I figure as long as I'm paying around $300 I'm in the right market.

The other question I was really concerned with was the weight of the flywheel. I guess that's mostly preference, but for smaller block engines, I'm assuming a lighter weight is better?

 

lighter flywheels cut out rotational mass, they dont add horsepower themselves but they make getting into your power zone quicker. As to how light you should go, you nailed it, its all preference. I would say that unless you want to be rebuying everything when you go boost, to stay away from the really light flywheel like the 7lb one, there are agruments both ways, but turbos dont play well with lightend flywheels, atleast not too light. I wouldnt go much lower then 12lbs

 

I just rememberd another site I really liked that might appeal a bit more then the other one. I used this site when I building my Del sol. LSDmotorsports.com, I used there company branded clutch in my turbo del sol, dont remember the exact one, you could seach these boards i guess, but it worked very well with that.

 

The basic idea is that the lighter the flywheel, the faster the engine will rev. This is great on track cars, and even for spirited normal driving once you get moving. The trade off is that the car will be harder to launch from a stop... this is why you don't see super light flywheels on drag cars.

 

If I'm not mistaken, a lighter flywheel will also let the rpms drop faster as well - nice at the track, etc. but maybe not as much on a DD. If it's significantly lighter than stock (and it's a car where the revs drop pretty quickly anyway between shifts) it could at least take some getting used to and you might notice you have to work it harder to go up a steep hill for ex.

If it's not significantly lighter though I wouldn't be too worried, but keep in mind I have no experience with aftermarket flywheels.

 

Ahh, specific weights...good stuff. ^^

Thanks for all the input, helps a lot gents. :thumbup:

 

Before somebody says I'm brining this thread back from the dead..... well yeah!

I want to see what more people have to say about it though. I want to know if a light flywheel can hurt efficiency at all. Couldn't make things better?
