Its an NPC 10" sprung button clutch, good for 300+rwkw, car is making 255rwkw atm

Clutch bites hard and the pedal is pretty soft. Takes a bit to get used to but once you do its an easy clutch to live with. Cost about $760 from memory. If your gonna get one think about getting there billet flywheel while your at it. easy to do it all in one go.

Round 1: lasted 1 week

I had one in my rb30/26 running 580hp and the preasure plate smashed after a week and destroyed my gear box. I was only running the cluch in no launches at all. It was a single plate 5puk from npc

Round 2: built stronger lasted 3weeks

From the last time it shit its self I sent it back and had it rebuilt to handle even more power. Funny thing is I'm running less power then last time. Now 450hp and the piece of shit clutch let go yet once again but this time it smashed the box clean off the block. I was changing from 2nd to 3rd. I should of learnt from the first time it let go. Now I will use what I know works. Hks or OS GIKEN or a orc or back to mal wood to get a custom built. So I don't have to pay labour to remove the gear box and pay for a new box and clutch because some price of shit clutch can't handle half of what it is built for. Buyers be warned. And customer service is f**ked when you send them back. They try anything to get out of it

I had a twin plate with flywheel from Direct. I welded it once but it was my fault. Handled 8k launches in an Autech Stagea with 500rwhp. Was a light switch clutch but you get that when running big power. Steve was excellent to deal with and Ive bought many clutches personally and refered him to mates on countless occasions. Theo Wollet ran his clutchs in the drag car. Speaks volumes.

he said he's making 455rwkw,

you'll hear horror stories from any brand.. I had a couple with Jim's.... no point getting into that...

with that power go a multi plate, with over 600rwhp in a GTR with literally 100's of 7-8k launchs and over 20000kms, and still going I can vouch for the OS Giken 3SC ( triple plate ) not the easiest to drive but you get used to it.thumbsup.gif

I'm having a NPC 10" ceramic button sprung clutch installed in my R33 GTR today (costs $1200 including flywheel). The GTR has around 380awkw. I was told that this clutch has proven to handle 600hp at the wheels so it should handle my power ok. I guess I will find out soon enough after running it in lol

I am having my OS Giken twin plate rebuilt - ready to swap back when the new NPC clutch gets tired.

Happy to report back in a month's time on the NPC ceramic button clutch.

Yea I am going twin plate but don't no which one to get npc or direct or Jim berry

    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies. 
    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
