LOGIE Posted December 27, 2013 Share Posted December 27, 2013 What do you plan on doing with it Marco? Forced induction? Turbos? Check Ryan Gs build in the projects section for good info and links. Quote Link to comment Share on other sites More sharing options...
David P Posted December 27, 2013 Share Posted December 27, 2013 The 1UZ has an aluminium block & head. Over time the con-rods were made lighter and lighter, the earlier lumps are the strongest. Quote Link to comment Share on other sites More sharing options...
Littler Posted December 27, 2013 Share Posted December 27, 2013 The better blocks are the pre 93/94 (I can't remember which year exactly) as it had the stronger bottom end. But as David said, the block and head are aluminium and the weight difference between the 2JZ and the 1UZ is incredible! I had one for a rainy day until it was taken I still wouldn't mind venturing into doing a TT6 1UZ Quote Link to comment Share on other sites More sharing options...
ibby Posted December 27, 2013 Share Posted December 27, 2013 I thought the old 1us were cast and the 2us and 3us were ally made! oh well live and learn! Quote Link to comment Share on other sites More sharing options...

I'm off to check these sites out now These sites are Toyota v8 based. any parts you need or info will be found on that forum.!

Marco79 Posted December 30, 2013 Author Share Posted December 30, 2013 Thanks for the response guys looking at a turbod V8 alternative for zoran in the future so doing research into viable options the earlier models are defo stronger and the ones to go for but if running forged internals is there any difference between models?

garethr Posted December 30, 2013 Share Posted December 30, 2013 (edited) I thought the old 1Us were cast and the 2Us and 3Us were ally made! Oh well live and learn!1UZ (4.0) and 3UZ (4.3) are all alloy. 2UZ (4.7) is iron block. Thanks for the response guys looking at a turbod V8 alternative for zoran in the future so doing research into viable options the earlier models are defo stronger and the ones to go for but if running forged internals is there any difference between models?Not if you are replacing the rods. Just for info: They have been known to do this under boost: As well as the forums mentioned, there are a few build threads on the Soarer Central forum, and also on Club Lexus, I think. Obviously on Soarers and SCs, but the principle is the same. The quick and dirty way to a turbo manifold is to start by reversing the standard exhaust manifolds to point forwards.
