I am looking at upgrading my 22RE out of a 94 toyota.  I am considering either the 2.7L out of a Tacoma or a 4.3L Vortec.  What type of modifications will I need to make?  Anybody have an idea of the installation costs (are we talking $1000 or $10000)?  
Thanks for any information.  

The 4.3, many mods. A 2.7, 3.0, 3.4, 4.0 would be alot easier.

Price depends on what you are using. New engine? Rebuilt? Junkyard? You doing the labor or paying somebody? If you are doing the work a good bet would be $2500 complete, beginning to end, including all the nickel and dime stuff that will set you back.  

Everything i have seen makes the 3.4 look like the way to go. Take a look here this site has a lot of info for yota's  http://www.yotatech.com/f116/3-4-swap-started-82145/  

I live in California. was wondering if you had done your swap yet and if you would like to sell the 22re if you are close enough for me to come get it?  

You are going to be better off checking www.car-parts.com to find an engine, this guy hasn't logged on in nearly a year...
