From what I've read swapping Toyota and Lexus V-8's into trucks and 4-runners is common in AU and NZ. Here is one site http://geocities.com/deonsv8hilux/ . If it will fit a 2nd gen it will fit a 3rd as well. Will have the exact same bolt pattern (3.0-3.4). All you need is a wrecked Lexus...
I'll have to find more info on this modification from the original website. There are some other pictures of a massive intercooler etc. This is installed in a truck but the Runner wouldn't be much different.
Do you mean like this. I got these pictures off either 4x4 Wire or the Pirate board. Was a custom job if I remember. I had checked into this at a local turbo shop and the owner said it would be fairly easy to do using existing parts from other turbo cars.
