Yaris pulley and flywheel upgrades

[E_Gatzke_27]

Has anyone installed the lightweight flywheel on their Yaris yet? What about the pulley system from Non Stop Tuning? Supposedly, the flywheel (upgraded model) is only 18 lbs. Ayone know about how much the stock one weighs? Also, the stock weights on the pulleys is something like 50 ounces for the crank, and over 20 ounces for the other two. They all get cut WAY down in weight with the after market ones. All that to make the engine rev quicker, and put more of those lost ponies to the street where they are needed most. The pulleys alone are about $300 after shipping, and the flywheel is an arm and a leg too. There is an after market clutch kit that adds 25% more grab with only 10% more pedal resistance. Anyways, if anyone has don this stuff to their Yaris, please respond here so I know if it is worth all the hard work to do that stuff now or later. Thanks.

I went with a LS7 Clutch and PP combo with an LS2 lightened flywheel. I used the hydrolics off of a LS6 for increased grip. It was about 50% increased. As for the lightened pulleys I deleted power steering and the A/C I removed for extra weight reduction. It lightened the front end by about 100lbs and took .1 off of my 1/4 times. The rest of the pulleys I bought a kit from ThunderRacing and installed light billet CNC machined aluminum. The car revs a lot faster now.

I have the complete pulley set. You'll see how good it is if we can make it to Renegade. Revs better, faster, frees up the HP (doesn't make HP, just frees it up), and if you don't lead foot it increases MPG.
