if you have the 5sfe 4cyl, then swap it to a 1mz-fe v6. thats the optional engine that came with it. if you have the v6 already, then turbo it.
thats the only way, unless you forge everything and build the shit out of it.
its possible friend but tough and expensive. do an extensive search, read the stickies and ull find all the awnsers you didnt want to hear. 100hp is a pricey goal.
