" This is a complete DIY installation guide for the 3 piece NST kit from NST - NonStopTuning "

NST - The Leader In 8th Gen Civic Pulleys

1.- park your car and make sure you have room to play whit the car

2.- jack up the car and take the wheel off and for better access turn the whe steering wheel all the way to the right

3.- disconect the battery(just for safe...)

4.- remove the 2 lil clips that hold the crank pulley cover

5.- unplug the crank pulley cover from the inner fender, it doesnt remove completly, cus it goes from fender to fender like the Si one...

6.- now you have acces to the crank pulley....

7.-open the hood and take a look to the left side (if youre in front of the car) so you can see the alternator and the pulley, and if you look closer... just under the alt pulley is the water pump pulley

8.- to remove the belt, first you have to locate the tensioner, its the big silver part you can see in front of the pulley, or you can just remove the alt first... its the same... i removed the alternator

9.- remove all the connections of the alt, they are 2 harnesses over the alt with a black cover... and another cable that goes in the black bracket over the alt

10.- to remove the alt you need to unscrew 3 bolts one over the alt(easy access), other in front of the alt (easy access), and the last one is under the alt(you need large socket[a lil difficult access])

the last one is the one that holds the belt tensioner(easy access[when you remove this, you can remove the belt if you hadnt])

11.- now you can remove the alt pulley, a friend helped me, he held the pulley and I used the impact wrench to remove it. note: he only used his MECHANICS gloves to hold the pulley

12.- put the new pulley and tighten it with the impact wrench
**i forgot to take a pic of the NST installed... but it looks exactly as the one of the Si**
so i use this pic of the K20Z3 NST pulley kit DIY

13.- at this point the alt pulley is done... but dont reinstall the alt... cus you need that space in the engine to get a good access to the water pump

14.- you can see that the water pump pulley haves 3 bolts on it, it was a lil difficult to unscrew those because the pulley turns freely so you have to secure it, or hold it, i tried to hold it with my hands and my friend tried to uncrew the bolts from under the car, we could unscrew 2... but the third was so dificult, so we just discover a new method to lock the pulley... you need a screw driver (not too big... but not to small)

you have to put the screw driver in one of the holes of the stock wp pulley so the screw driver passes from one side to other, like the pic and now you can losen the bolts on the wp,

15.- then, when you have removed the 3 bolts, take care and hold the wp... cus it can fall so hold it whit your hand, then remove it and place the NST one, and reinstall the bolts

16.- now you can reinstall the alt, just screw all the bolts you unscrewd.... one over the alt, 2 hiden on one side of the alt and the tensioner one that is in front of the alt

17.- well, now the crank one... you need a 180+ lb/ft torque impact wrench for this.... cus its very tight, and a 2nd person who is gonna shift in 5th gear and press the brake(this is to lock the crank), and just unscrew the bolt and remove the stock pulley, i didnt use the pulley remover tool, but if you have it, use it... be carefull to not loose the KEY of the pulley cus you need it and its a small piece
**as my impact wrench wasnt powerfull to remove the bolt, i ask for my dealer to install it... and they dont let me take pictures(cus they doesnt charge me anything, and doesnt want that his manager know about it)** but uninstalled its like the one on the Si

and this is the pulley key... same in both engines

18.- install the NST pulley, make sure it fit and dont force it too much, when installed it has to spin freely, try that... if its not spinning its not installed propertly, remove and try again

19.- re install the belt, here i drew a diagram of the belt

20.- move the tensioner until the other person places the belt in position(the belt can be K070760 or K060760[if you got the K060760, just check that the belt is aligned propertly on all the pulleys, if you get the K070760 that’s even better... it fits 100% perfect])

21.- drive it

22.- love it

23.- share it

24.- NST FTW!!!

I think this deserves some rep. Nice DIY.
very nice DIY....so hows it feel? any difference and i noticed you have racing seats of some sort..how did you get brakets for the seats?custom im guessing

i was waiting for this... :thumb:
theres a big change! the car revs very fast! and its feel very good
no engine light, weird noise or any other problem... everythings perfect
also, the ralenti(idle) problem had gone,
so you can kill 2 bird whit one shot....gain in performance and solve the idle problem...

and i have BRIDE ERGO II seats whit TAKATA harnesses... the brackets are from www.wedgeengineering.net and RECARO's seat rails, also from www.wedgeengineering.net
Really cool ! Looks pretty :p..
so uhh.. what excactly benefits? less resistance? que? :] thanks!
very nice, thanx alot maby would you mind to post some pics of the seat from inside, that would be awsome
Whew, didn't know pulley's were that high... But hell, I might pick some up when I get my bonus. 7-10 HP is awesome from just pulley's.
Great job el ben2 :thumb: I have these pulleys on mine and they kick ass, I would recommend them to anyone looking for a more preppy car.

Damn, what a solid writeup!! I wish I had instructions this detailed when I put on my NST pulleys. NST pulleys are still probably my fave mod done to my ride.

NST FTW!!!!!
How about a video of the car revving and a quick 0-60? :)
