Hmm should i have used loctite blue? or some kind of threadlocker since i installed it with handtools?dammit im too lazy to go do all this again. Please tell me it probably wony get loose lol.

 

i just dont know witch one to get ZPI or the NST underdrive kit im cunfused

 

ZPI? is ZPI back? im sorry but i thought they went out of business and now owe hella ppl. Every one that buys pulleys gets NST though. Seems like they are the leader. I personally bought brothers. works fine for me. Though it actually seems like im gettin less MPG after the pulley install. SInce revving faster kills gas?

 

nst, has a underdrive pulley which yields better gains, from my understanding. i will take it to a tuner shop here soon, so they can put it on, cause i dont have impact set, and compressor... talk to nstonaim=screenname, he will answer any questions as he did to me, hope that helps..
also with a underdrive pully you need a new belt, and with just a light weight you use oem belt... belt for underdrive is k060735

Well if you have the OEM diameter pulley, you could do it yourself without an impact set. Very easy. Save the 100 bucks.

 

dude u cant do it without an impact set. i squirted it down with WD40 and had some pretty hefty friends work at undoing the bolt and it wouldnt ____ing come off. and the car was in gear but the the pulley kept turning a little bit so you couldnt unbolt it completely. help

 

u gotta put it in gear and press the break, so it doenst just turn it. But all that dint work for me, if you dont have an impact set , its still very easy, and kind of funny ina way. Stick yur socket wrench handle, into some kind of bar, like a galvanite nipple(mine was about 18 inches long) and place the bar into the floor, kind of hard to explain but this will make the socket Stick into place, because the car will not push itself off the ground, if the socket is in place and you crank the engine, it will come loose, DO NOT TURN IT ON, just give it a short crank so the pulley turns.

 

dude im going to try this are you sure im not going to ____ my timing up or anything? im a 5spd so just like crank engind for 1/2 a second? i get what you mean. useing a hollow metal pipe hats long enough to touch the ground. do i got this?

 

great writeup, this is definitely an hour tops install with the right tools and a friend. adding this on my to-do list =p

 

yeah, put yur socket on the nut, extend it with a bar onto the ground.make sure u actually like kinda stick the bar into the concrete. i know itz concrete but atleast try to make the bar stay into the ground, then I (you dont needa do this) but I used my feet to keep the bar in place, just in case. And i had a friend crank the engine. Yes im terrible at explaining but i think you get it, Since the socket wrench wont move, since its in the ground, the crank will turn itself. And no u wont ____ anything, just dont turn on the car since it seems very dangerous. Just ONE crank and the thing came lose already, then u can loosen it by hand. I think i was actually the first to do this without a impact wrench, Alot of people actually flamed me and said i was dumb, but i did it and its fine. If u wanna be safe, put a pinch of loctite blue (thread glue) on the nut wen u tighten it back up since once again you would be tightening it without an impact wrench.

 

MANY MANY THANKS!

I just did the install in about 45min, definate change in the power band!

 

So did you do it the ghetto way, without an impact tool? On some other thread, i gave this same advice, now they are all calling me stupid. claiming that the wrench will shoot off and break something.

 

^^^ sounds like the dumb ___ way if u ask me. not smart at all. just one question though has anyone installed one ran it for a couple thousand miles and then tried taking it off ? wwill i need a puller set ? since the stock one slid out. this one wont though. i am trying to go back to stock for the mean time my car is not in use and just swap it out when the nst one comes in. since i get the nst for ten bucks more after selling my zpi one thats the difference. so does a harmonic puller have to be used ? thanks

 

^No need for any pullers...just your hands and a little force possibly.

 

So just to be clear, is this doable with hand tools? Will popping it into gear and using a breaker bar work, or should I skip that attempt and just prop the breaker bar on the ground, pull the fuel pump fuse, and crank her up? Or rent/buy air tools? I'd like to avoid spending more money on tools, but I'm willing to if that's what it takes to get the job done right.

 

Popping it into gear will not work, Or atleast it did not work on the several cars that I've done it on. The shaft will still spin.

Propping the breaker bar is your best option if you dont want to rent air compressor and air gun. But the only way you can do it, is if you really understand what I tried to explain. Make sure the bar is propped in the right direction and is pretty stable into the ground. Dont forget to just crank the engine and to not start the car.

And if you ever did want to pay a little cash. renting air tools would be quick and easy. So its up to you.

 

Righto. I've watched it done on Hondas and such before and I understand how to do it on the tC. I think I might get an air compressor and an impact wrench just to be safe (and to make my other projects a little easier). Anyone know how much psi will be enough to pop that thing off?

 

should come right off with 120psi,that is about what i have the impact set at for most things like that over the years.

 

righto, thanks for the info BZinn.
