Celica ST turbo upgrades

I have a 1994 celica ST stock engine. What turbo could I put in and how much would it cost? What else would I need to do to make it run well?

Thanks.

how much are you willing to spend? and is your car your daily driver or you want it full race?

This is my every day car. What I want to do is either put a 1990-1993 GTS/transmission in or I think its the 2.0 L MR2 engine that sometimes comes stock on these years of celicas in Japan, not sure if it will meet emission standards though. I'm looking to spend up to $2500. Is that possible?

So far, I have no complaints in my car. It’s running very well. The parts are tough. I make it a point to check every single part so as to avoid any problem in the road. Hopefully, I haven’t had any trouble with it during rush. I had replaced its Toyota Celica cold air intake last week and I’m fortunately enough that it’s only the part that I needed to purchase for it this month.
