I'm in a '93 Lexus ES300. It has the stock 3VZ-FE and tranny (don't know the code). I want to know what a feasible swap would be, not involving TOO much work or downtime. Here's my thoughts:
The newer ES300 (3rd gen., '97 - '01) ran a 1MZ-FE. Same displacement, but higher horse and torque rating. Would a swap be relatively simple, and what would be involved?
The other option was to take a newer 5VZ-FE from a 1997 Tacoma.
Also, would either of these require a matching tranny from the donor or could I keep my current tranny?
What I'm really asking is for any info at all on a feasible swap, because I'm looking for more!

Appreciate the help / info.
