I have a very ambitious project but I am just in the planing phase at this point. I have been a member here for a long time lurking and I think this is finally my opportunity to do UZ swap something. I'll elaborate more on the chassis once I have it stripped and prepped, lets just call it "Project Tetanus" for now.
Initially I was pretty sure I wanted a 2UZ but after careful consideration I'm not so certain that the added weight will be worth the performance gain.
That said the 2UZ seems to be easier to source locally and much cheaper, plus with an iron block I can imagine it will handle power adders (turbos or SC) at higher boost levels. Which brings me to the results that stand before me:
1UZ - Slightly more expensive but lighter weight and aluminum block.
2UZ - I can source pretty easily for fairly cheap. Cast iron block so potentially able to tolerate more abuse (read boost?). But will that long stroke hinder more than help?
3UZ - Light weight and more displacement, but over twice the price of the 2uz locally.
One of my goals is weight reduction and the original motor is a 4AGE, so I'm sacrificing weight advantage already, but I do have a ~500whp power goal. Either motor I go with I will be adding Lextreme rods, forged pistons and full internals. I'll toss this in the mix too: If I do go with either block I keep reading that the VVT-i heads flow better, but is that true for all models?
Again, this is just early pondering, but thanks in advance!
