i know this has been asked before and i know some people have certain beliefs from international forums,stuff they have been reading up for years etc...
do you guys honestly think the 4AGE-Z pistons are forged?
im hardcore toyota really so im not tryin to diss it...
look at three top piston makers,
ACL ,ARIAS, WOSSNER(german car pistons), the pistons are high polished in color...
has anyone purchased forged spanners or any other tools? try looking in gans the next time you're there....
now lets define FORGED STEEL aka FORGING as per http://www.wikipedia.org( http://en.wikipedia.org/wiki/Forging)
In modern times, industrial forging is done either with presses or with hammers
The most common type of forging equipment is the hammer and anvil
ok so forged steel is highly reflective and bright silver in color, but the toyota oem piston looks ceramic coated... ok so why would you ceramic coat a forged pistons? its a cheap process so why does R9000 pistons dont come ceramic coated? ok so we may say the pistons are semi forged? which half is semi forged? the bottom is cast cause its the same color as the 4age piston,.. the top is ceramic coated...
everyone relies on google, and over sea's forums and other local forums, rumours and myths spread by using copy and paste... since search engines cause this, could someone try and find a piston manufacturer who makes semi forged pistons....
if you read up on the forging process, you would know that the if the top half was bonded too cast iron it would break off on the first hit off the high pressure hammer, and if its cast iron that has been forged, it would be very expensive, and it would have been completely forged, and there would be no need to coat it, so could toyota be the only company in the world to create a semi forged pistons?
i believe this was discussed in this post
http://www.tolken.co.za/twincamforum/viewtopic.php?f=2&t=51540&start=0
but whats the conclusion?
if i ask you guys how to do underbucket shims, everyones gonna say the yaris shims work, simply because of the article thats
floating, has anyone in the country tried and succeeded in it? if someone wants to turbo their 4AGE, then the usual ZE pistons come up, then some believe the 4agez comes with a forged crank, well i have not found that out any info on that yet..
from what i know, the 20v's and 4agze have the same crank, i have yet to see a 4age 16v crank too compare.
alot of power is held back by forum articles, failure is caused by many myths and beliefs'... the best way to modify a car is by trial error if not by a well experience tuner.
