I have a considerable amount of technical info available for these cars.
In addition to the standard Haynes and Chilton manuals I have
Original Toyota
2TZ-FE Engine repair manual
2TZ-FE Emissions Repair manual
Original Toyota repair manual for 1993 Previa (over 900 pages) - US edition
Original Toyota wiring diagram for 1993 Previa - US edition
Original Toyota Automatic transmission manual for A46DE and A46DF transmission
Thatcham Previa Methods Manual for Body repairs and respray
Even though based on the 1993, the 2TZ-FE motor did not change throughout its 10 year production. After 1994 they received an OB2 diagnostics port to be compliant with motor industry standards but again this was not a fundamental change.
The Toyota manuals go into far more detail than the Haynes/Chilton as I am sure you can imgaine. If anyone needs some info I will be happy to scan the original page and let you have a copy.
For you Estima guys I have the original 3C-TE manual as well.
Thanks for your valued offer of help Propnut, I'm sure the Previa and Estima owners will be most grateful.
