yes, thats definately another factor. A while back I asked if the folks updating would also give a brief description on how the car driven.

 

^^^And we started giving them. :D

 

It is my belief that Toyota didn't have a mileage figure in mind when they designed the engine. It is afterall a Camry motor. That being said it was never made to be a high performance engine, but what small car engine in mass production for cars under 20K are? I'm not going to go off on a tangent here about engine design and purpose but time will tell whether or not the aftermarket crank pulleys being put on the TC have any real part to play in the life of the engine.

 

And, for example, forced air induction has been the cause of many an engine failure but we still seem to be turbocharging and supercharging engines all the time.

 

thats true! I also dont want to go off on a tangent, but I wuold think the folks that decide to go F/I would be financially alright to be able to get another motor if things go bad whereas pulley owners may not.

ANyhow, almost 1K miles w/ AP pulley on 07. Everything fine and dandy. I have been mashing the gas pedal more recently b/c of the colder weather.

 

the 2azfe is a work horse motor, my cousin had one in his pick up truck and that thing took a hell of a beating ( off roading ) and still ran strong after 160 k when he sold it.

 

with all of the news so far about no negative problems with the pulleys, ive decided to get a set from NST myself.
hope im not the one to finally say "THE PULLEYS RUINED MY CAR!"

 

lol, still going strong...and my car gets treated like s%^t...i have about 10-13K on the pulleys.....

 

I'm at 30200 and about 21K+ on the pulley................still going strong and I've punished it the past 2 tank fulls trying to get to where I go as fast as possible ......still getting 26+ mpg and average coasting highway speed is about 80-90 on I-95

 

Just got the NST set put on last night....i had some weird idling vibrations later the night that seems to go away but other then that.....the response is quicker....you can feel a decent change....i will be monitoring idling and anything out of the norm and keep you guys posted.....
on a side note the front sway was put on as well and kicks a$$....car is tight

 

Update from u guys!

 

27k on car, about 18k on pulley, about 100 miles on boost lol
no problems, except traction

 

~23K on the pulley and nothing. Installed my Tanabe NF210s Saturday and thought I would take a look to check for any leaks or cracks.......no oil leaks, no cracked oil seal, no deformation of the pulley. All is good

 

for a stock diameter pulley...should i get zpi or nst? nst's is on sale for 110 shipped through a GB right now....how much power difference is there between the two? i've always like zpi's one better.....

 

Anodized ZPI would be good....stronger and same weight. Both free up excess "drag" on the crank......they don't "produce" power though. The just free up drag which CAN help the engine work more efficiently.

 

is the zpi lighter than the nst?

 

I think NST is still a slight decrease in size compared to ZPI....not 100% sure though. NST will be a hair lighter if it is a little smaller....honestly, nothing that will be anything noticeable.

 

Yeah, it's a 20% reduction compared to the stock pulley.

 

nonono...the nst stock sized one

this is the one i'm referring to...

If it is truely the stock size, then either or will be fine (same weight... ~1.1 lbs).....but, check Non Stop Tuning's site....there's no "stock" size pulley....it's only a 20% underdrive pulley and requires a different belt.

The picture on the site you have is the same one as on the NST site itself......I would double check to make sure it truley is the stock size pulley.
