So I was driving to work this morning and come to the realisation that the clutch in the Soarer seems to be on the way out.....normal around-town gearchanges are fine, but if you punt it in gear it'll flare like an auto, especially when you're hitting or in boost. Worse too if it is part throttle, as you can get it to flare a good 2-3000rpm (combined with a lovely smell), whereas full throttle gives you enough power through to the wheels for them to catch up to the revs and stop the slipping.
Anyone got recommendations for a good street-suitable girl-suitable (it is the missus's car afterall) clutch for a 1JZ/R154 that can handle 250-300odd kw? As far as I can tell it is still running the factory clutch, something a little heavier wouldn't be a problem (it is lighter than the factory clutch in the AE102, somehow), but don't want to splurge on a twin-plate or anything exotic if possible.

Yeah I've come across the Exedy kit, wondering how much extra it'd be with the lightened flywheel too......what I go for will probably depend on how much my bonus is that I get next week.

I got a custom clutch from KB Clutch for my 1uz using the R154. It uses the standard 1jz pressure plate modified for 1600KG clamping pressure and a 6 puck clutch. I can't remember the exact price but it was around the $500 mark. It is an easy clutch to use and with the standard hydraulic setup it's still light on the left leg.
Clutches aren't that expensive until you start buying name brands and multiplates. I also have a twin plate tilton that i'm going to try out at some stage.

update, clutch fitted. Very soft on the leg and easy engagement, just have to wait to bed it in before i give it a boot. Apparently the HD organic clutch i previously had in there still has plenty of grip, so if anybody wants a cheaper option i will be putting it under the for sale section

HD Organic is similar to a stock clutch with a bit more bite and easy engagement. A cushion button is made with ceramic material and has more bite similar to a button clutch but is not as harsh on the engagement. If you look over the website it gives a better description of the products http://www.npcperformance.com.au/index.html I went with NPC as the price was good in comparison to everywhere else i got a quote from and they have made some clutches for some big HP drag cars and street cars with no complaints, also postage was only $35

Tai,
I dropped my original pressure plate at KB clutch and he did the rest using a flywheel sent from dellow and one of his clutches.
There are only a couple of leaked photos of the turbo setup in clayton's build thread. Trying to keep it under wraps till it's close to being finished. The turbo 6's aren't bad. I've been driving a 97 vvti around for the last 6 months.
At Antonio said, a HD organic clutch is exactly the same as the factory clutch arrangement (full face clutch disc) with generally a slightly higher clamping force.
A cushioned ceramic clutch would be the next most common clutch is basically the same as a standard clutch or a puck design with a ceramic and sometimes ceramic/metallic friction compound which has better heat and friction characteristics, especially under higher clamping forces. The cushioned term refers to the springs located in the centre of the clutch disc which helps eliminate chatter. This is why you will hear multiplate clutches chattering away when not engaged.

Just remember , In a manual car , the clutch is designed to be the weakest link , ie , it wears out faster as its easier to replace and better than breaking stuffs .
Go to hardcore a clutch and you will start breaking tailshafts and diffs , as others have done so when upgraded .
Always go with a cushioned centre specially on a street ride .

Or should i future-proof and go the cushion button clutch
Ceramic The cushioning between the ceramic linings allows this style of clutch to have good engagement feel while providing the benefits associated with ceramic material. NPC recommends the cushioned button clutch kit to daily driven high performance road cars.
HD Organic This style of clutch is ideal for 4 x 4 enthusiasts, tow vehicles, commercial vehicles and modified road cars used everyday with occasional strip use.
