New NST Pulleys for the TS

[CASTREX]

OK OK... sorry! A little confession to make... I was not able to install the pulley until a week ago... Work a lots of things to do kept the pulley in my desk for several weeks...

But is finally on and after a week of driving with it I can now post my impressions!

The installation was really easy... I took like 15 min. I didn't do it sooner because I didn't had an impact gun to pull out the OE pulley. I went to a friend who had one and it took us longer to loose the alternator than taking the oe pulley off and the new one on.

Amazing product!

Probably the best bang for the buck out there for the 2ZR-FE engine.

Unlike the gains from my Fujita CAI or exhaust that you can feel them on the higher revs, the NST underdrive pulley provides gains all across the rev band...

Don't buy it expecting a huge improvement... but I can tell you this is something that you can actually feel!

iirc the back to back dyno testing that Richard Holdener did for the 1.5L Yaris underdrive pulley showed a solid 3whp gain. Now I can tell you that the OE pulley from the Yaris TS is almost twice a big as the OE pulley from the 1.5Yaris and the weight savings are much larger on the Yaris TS.

I would not be surprised if the actual gains in our car are around 5whp with this U pulley.

Other impressions:

The throttle response is improved... I love that rev matching down shifting is easier and smoother now.

For the people worried about the use of an under drive pulley...
I have a DVD audio system, 6 speakers and 4 channel 350w amp and use the A/C every day... no problems after a week of driving!!


Finally a little side review:

I also installed the NST metal bushings. The ones that go one the engine side....

WOW!!

I love them! I already had the NST SSK but now with the cable bushings, the gears feel really sporty...
When I push a gear on you can almost feel a click when the gear goes on... no more mushy feeling!



I've been driving like during the last week!!!

Thanks NST!!
