[robrub00]

I found a 2rz I belive wreacked truck for 450.  Havent looked at it yet.  It is a 2X4 SO i AASSUME IT IS THE 2RZ.  iS THE ONLY DIFFERENCE THAT THE 3RZ IS STROKED?  IS ALL THE REST THE SAME??  OR ARE THERE DIFFERENCES??  WOULD i NEED A 3RZ COMPUTER TO SEE ANY DIFFERNCES. 



http://en.wikipedia.org/wiki/Toyota_RZ_engine  HERE ARE THE SPECS i FOUND iN MY SEARCH.  THEY ARE THE SAME BORE BUT DIFFERENT STROKE.  sO cOULD i BUY  STOCK CONNECTING RODS TO MAKE THE 2RZ A 3RZ?  mIGHT NOT BE WORTH IT i JUST AM CURIOUS.

yep,  from what i understand the 3RZ  is a much larger bore size

The 3rz's were available with a oil cooler if the truck came with a factory tow package - mine did.  The heads on both are the same though.
