According to Mike of NST, they will have more products for us in the future if we support them and buy their current products.

NST FTW! Everyone else who copies them FTL!

Is your Yaris a New generation or old like the echo Hb??

I am very interested about this information becasue my car is a 1.3L 2nd generation (like the one on the signature)

Other thing is that my country is very hot so we always use air conditioner
if i get to install the pulley...will it affect in any way?

Thanks in advance

Yeah, you could do that... But buying the CR pulley now helps fund R&D which will get the rest of the pulleys out sooner. You would also save some gas if you bought one now, my MPG improved 1-3. It would probably be more convenient though to get it all done at once. Regardless if you wait for the whole set or get it piece by piece, your going to really enjoy the results

I have the NST CR-Lite and could not be more happy with it. Better response and better MPG.

NST FTW! All other copy cats FTL!

The good: I'm still lovin' the NST pulley. Couldn't be happier. Mid-range really is much more punchy. Feels like more than 5 hp but who knows. All I know is that it revs much faster and seems to pull harder. I can't wait for the other pulleys!!

Other than the increased performance, the car idles a little rough, especially when warming up. Even after it's warm I can definitely feel the engine vibrating more than before. This is only at idle.

I have the five speed and I've noticed that takeoff requires a little more clutch than it used to. However, once rolling, accelleration is smoother than before. The last thing is that the car doesn't want to creep as easily at low speeds which sucks in traffic. Buuutt.... accellerating away from the toll booth is a blast!!! Anyway, my 2 cents.

If I remember correctly, the manual says not to warm up the car, just take it easy till the light dissapears

I've heard mention of a harmonic balancer when it comes to pulleys. Anyone care to enlighten me as to if the pulley needs one or not?

well, after now having the thing in 24 hours, I can feel a few differences from before... For one, the engine does feel more responsive, looser, easier to rev up. How can I tell? My ger-changing timing's all off and jerky now, the engine gets up to speed faster, so I'm over-revving by the time I engage the clutch the "old" way. Should take a couple of days to get adjusted.

Although, at low speeds, the engine is a little more shaky, the advantage of a havier pulley and/or flywheel is more inertia, allowing the engine to spin more smoothly... But, that's also just a matter of getting used to it.

Over all,

I like mine, but yes it does idle rougher sometimes when the rpms drop under 600. overall im happy with it, definatley more power throught the entire rpm range. funny thing is I really notice it when im engine breaking, it definately helps stop faster!

Yeah...i feel the same benefits in mine...
However my mechanic was telling me what i might experience after changing the pulley...and he did mention that there might be more vibration now...and there is a bit like you guys mentioned..but nothing i can't get used to..
he said its due to a lighter pulley...plus the OEM pulley had some kinda or rubber gasket on it to help dampen the vibration?

No such rubber on the OEM pulley. I saved my old one and inspected. All metal & paint.

Mike, your link to the DIY installation is dead? Also when will you be releasing the pulley kit (WP and Alternator pulleys) ? I'm interested.

Mine has a rubber ring between the hub and the grooved pulley ring. Most OEM pulleys do. Check yours again and you will see it, and feel it.

Do you think it might be possible to swap that ring with the new pulley? Would the NST still fit? Or maybe NST would like to add a rubber ring for an extra buck or two?

No you cant swap it out. Adding a vibration dampner to the NST would probably double its price, and add weight. Slight increase in vibration is the nature of the beast with a light, solid pulley. It was barely noticeable on my car.
