Recently I opened up a 2TZFZE engine. That is the supercharged Previa or Tarago or Estima in Japan. I disassamble the extra motor and took a set of piston and rod to my engine builder and let his expertise tell me what they are made of.
Needless to say, the rod and the piston are forged. There were some speculation that they were not but they were verified and confirmed. So you guys with Supercharged Previa would appreciate this news. The rod from the 2TZFZE is very beefy and can handle 600 hp stock.
I compare the Previa rod to the Lexus GS400 and the earlier model SC400. The Previa is more beefier then the above mentioned. With forged internal in mind, now we can really boost the engine. Personally, I would change the stock head gasket to MLS and head bolts to ARP studs.
Here are some pictures. Note: The picture of the piston you see is from a 170,000 mile Previa.

My engine builder was impressed with forged internal for stock motor. Since the 2TZ rods are shorter, it would be stronger too. The 1UZFE had proven to handle 500 rwhp in stock form. The 2TZ would handle little more then the 1uzfe.
