Hello Everyone. I recently just did the swap in my car and I am on my way to wondering what performance mods I want to do next. But first my main question is what clutch do you prefer for all out street performance that will hold around 350 torque. Let me know and if you have any tips to let me know. Thanks

My suggestion is go with the ACT heavy duty street/strip. It's rated to something like 365bhp, and it won't "chatter" or feel "grabby" as it engages, which means you can be just as smooth with it as with a stock clutch. The pedal will be a bit stiffer but you'll easily get used to that.

I own an Exedy Stage-2 and I'm not too big a fan of it. It's impossible to be 100% smooth with, which I'd be able to live with if it weren't for the other problem, which is that it slips very easily.

<tl;dr>For the first 400 miles or so it would barely hold torque. I tried to take it easy for the breakin but even so there were times when heading uphill, shifting into 2nd and simultaneously giving it gas while engaging the clutch, it would still be slipping after my foot left the clutch pedal. I had to teach myself to be damn sure it was engaged before giving it any gas. There were also a few times where if I got on it a bit and started to make decent power, it would struggle to hold and RPM's would rise slightly disproportionate to the increase in acceleration.

That part's cleared up now... once engaged it seems to hold torque fine, and it drives as well as I'd expect any other puck style clutch to (sharp engagement, try to slip it and it makes the car shudder) , but any time I try to do anything dumb with sharp engagement like clutch kick to break traction or 'peel out' from a stop, it will break its hold from the flywheel. This past summer it slipped so bad that every time I shifted for a week afterward it would make an unpleasant grinding sound as the disk engaged the flywheel.

I also came across a thread on a Honda forum where someone had a Stage-2 on their turbo civic and it was slipping on the dyno. I forget at what hp range it was slipping but it was before his goal which was obviously below what the clutch was rated to hold.

I like Exedy stuff, they're an OEM and I've never experienced or heard of any outright failures, and I had a Stage-1 before my 2 that I loved and never had any problems with... I just feel they just didn't do as much R&D as they could have when setting out to make a ceramic puck style clutch.

My stage-1 disk still has most of its meat left and I'm thinking of using it with the heavier stage-2 pressure plate. Seems to me if the puck disk likes to slip then the organic disk would hold just as much power if not more, being that it's got rougly 3x the surface area. I'd just like to come across a reason why it'd be a bad idea before putting in the effort and then having trouble with it a couple months later. </tl;dr>

There are 2 big clutch companies that sell the wrong clutches (maxima clutches) for the sr20, i know one of them being ACT based on their part numbers. They are similar but not an sr20 clutch. I dont remember what the difference was or the long term repercussions of running that clutch. Hopefully someone else will chime in.

As for my car supposedly it has a nismo clutch, which im not sure even exists. It doesn't hold up to a 2871rs @ 9psi.
