i'd like to do this mod, but i'd like to know if there are any cons to this type of mod. does anything get worn out from changing pulleys? changing pulleys changes the cam timing right? how hard is the install? i know theres a diy guide for iton here somewhere i jus want a straight answer from someone who has done it.

so i read every lil facet about pulleys on nst's website and these lite pulleys are the same diameter as the oem pulleys so they dont change timing in any way, right? its because they dont weigh as much as the oem pulley that makes better use of the engines output. am i right?

Crank Pulleys and accessory pulleys have nothing to do with cam timing, whether they be underdrive, overdrive, or simply light weight variants. The concept is in regards to the rotating assembly and the transfer of horsepower between the crank shaft and the accessories which translate this horsepower into the services they provide. ie the alternator, a/c, etc.
Adjustable Cam Gears, also called cam pulleys by some, are directly attached to the camshafts and allow the individual tuner to change the timing of the camshafts, thereby changing the powerband of the engine. Adjustable cam gears are usually used in conjunction with aggressive aftermarket camshafts and wouldn't do much for mildly modified engines. Feel free to look for me on AOL Instant Messenger at the screen name NSTonAIM should you wish to chat about any of our products in further detail. I would be happy to be at your service.

my problem is i have a dumb ass friend who works on cars, who has an accord with a turbo h22 engine, that thinks he knows everything about cars. and my dumb ass listens to what he says sometime and he told me it will change the timing. this coming from some one who works at a local monroe shop, and works on peoples cars while stoned.

I got my pulley on today, and there is a nice bump in low-to-midrange. Can't feel much when winding it up, but that's fine.
My only tiny gripe about this pulley is the timing notch is too small, barely there really. Won't matter much until smog time, though, since the car tunes itself. Overall, VERY nice product.

Start looking under your couch cushions, in your ashtrays, and old jean pockets boys and girls. New pulleys are a comin!

I understand that it might not be a good thing for vendors or NST to post a dyno chart of before/after, unless the results are premium, but I'd love to see what the real world results of this are...hopefully somebody has access to a dyno for after the GB...gotta see if this is just doing a mod to do a mod...

Scroll down on the first page and you'll see dyno sheets from an Acura TSX and Lotus Elise. If NST can make power on a Lotus, you think they can handle your Yaris? |
