Here is a link for Mellings 3uzfe sleeves.
http://www.mellingcylindersleeves.c...icleId/53/New-Sleeve-for-Lexus-43L-3UZFE.aspx
The 3uz uses a 91mm bore vs the 87.5mm bore of the 1uz. IIRC the 3uz stock sleeve was only 1mm vs the 2mm for the eary 1uz. Like others here have recommended it is BEST to NOT bore the stock sleeves at all. Replacement brings with it other concerns including sealing and proper alignment.
