looks like its time for me to upgrade my exedy HD clutch, ive decided on the NPC 330kw rated organic

I actually dont like the stock feel to these clutches, are there many options with how heavy the pedal is, eg. stock feel and heavy or very heavy etc..

What should i ask for ? i want some firm pressure in the pedal and it to bite when i pull the next gear ...

Maybe ask for a smaller pressure plate? I love how the pedal is soft as a stock clutch.. I even thought I installed it wrong when I first when to press the pedal.

This ^^

It's due to the larger spring diameter. More leverage = lighter pedal feel

Exedy HD is just an OEM cover, modified and sprayed some homosexual pink. The difference could be a many things, because the pressure plates are modified they could clamp differently. Also you may be using different plates.

Yes, smaller clutch, lower rating i.e. less clutch friction material to flywheel contact.

I can tell you, my carbonetic 10" feels like a stock pedal, but when you want to drive it, it bites hard, it bites so hard that the car thumps lol

Do i need a lightened flywheel for 300kw's? is there a danger of the flywheel comming off? was just reading a thread about it..

nah stock flywheel is fine, just torque it down properly and loctite up the nuts.. however NPC did recommend me a Billet flywheel for extra, but I thought I would save that money for something else.

Nope, not needed... Use the correct torque settings... Pretty rare for one to come off, link?

thanks fella's, great to have such a great wealth of knowledge at hand, will let you know how NPC organic goes, although its probably know fact round here :yes:

the ultimate test will be some 1/4mile attempts at willowbank with some 2nd gear burnouts and 4000rpm launches at willowbank, would like to see some high 12's hopefully with practice.. :woot:

tell us your build intentions and your driving habits first.

well 90% im very kind to the clutch and drive off boost, other 10% is a drag or a 2nd, 3rd gear hard pull to get past some slow traffic

      rb20de neo +t conversion - boost pressure sensor needed?

      By Neostead2000 · Posted

      Agreed with the rest. Also at least based on my own research, there are no readily available stock or close-to-stock RB20Neo maps that you could download and use as a base were you to buy a complete standalone ECU, and the regular 20DET maps don't really work well so you'd need to take it to a tuner if you have no experience. I installed an AEM V2 on my 20Neo+T and had lots of headaches until I got it to run and idle properly but I've yet to remap it fully. You have to start building up your timing and fuel maps entirely from the ground up; even the ones for a 25 didn't work at all.

      GOT SUM's RB34

      Got some decent progress after work yesterday and also today. Got the ECU all wired and passenger side interior all back together. Kept the wiring up nice and high to avoid people standing on it. Got the surge tank relays rewired and tidied up the pump wiring and cut a hole to bring the cables through.  I found a spare USB cable I had lying around so I decided to cut it up and see if I could use it for my CAN 1 bus. Turned out one of the pins I needed was to the shield of the cable so i cut it up and desoldered it and resoldered to the correct pins.  Had the issue with the powersteering hose hitting the A/C compressor and fan shroud. I pulled the bracket off and modified it to remove the front mounting point which now clears it all. Will keep an eye on it to see if theres any signs of fouling once it's up and running.

      So today I went well outside my comfort zone (again) to replace my valve cover gasket.  I have had a big leak over the exhaust leading to a lot of smoke and smell every time I drove it. The leak was in the rear driver's corner.  The job wasn't hard as such, just a bit finicky and time consuming.  The old gasket was rock hard and broken right where the leak was.  The leaky corner had so much sitting oil in it.  The good news to my amateur eyes was no buildup or sludge under the cover. It all looked fairly nice in there.   I haven't started it yet. I ran out of light and body when putting the coils and injector loom back in. Probs only 30min left for the morning.  I was so nervous putting the cover back on, I must have lifted it 5 times to make sure the gasket was still seated properly. God it's going to be nice to be leak free and not make other traffic light queuers think my car is about to explode.
