Not much if you are a very good fabricator and do everything by yourself.
You will also need an access to a machine shop, lift, TIG welder, and all the tools in the world you could imagine.
However, it could cost your right arm and left leg if you have someone else do it for you.
(Someone did this and it costs around $15k)

You can't just drop it in and be done with it and expect to beat a stock GTS. Yeah, it's a great engine, but it's heavy, and without proper upgrades and tuning, your increase in power will just be negated with the weight. Now a stock 3S-GTE on a GT-4, that's different because of AWD, or the RWD on the MR-2.

what's the weight distribution on a GT4?

3S-GTE Swap as described on another celica site.

Although not for a 7th gen and Some have disputed the validity of their cost projects but that aside it kinda gives you an idea of what's involved doing an engine swap

and if you contacted Toysport they might give you an estimate, or an idea of if it's even worth it. Or they might just laugh and hang up, who knows.
