Help with the 3stge swap, 3sgte swap help? Options

[x94celicagtx]

I am wondering about the 3stge enigne swap for my 94 celica gt with 170 000 miles on it. My car is just too slow. I want to put the 3stge enigine in my car. I found the 3s engine on www.totaljdm.com and it is $1600 shipped to my house. It says it comes with the engine, turbo, intercooler and ecu. What else do i need for the swap? And i have heard about a lot of trouble when it come to the wiring harnesss. Is this true? Where could i send my old harness and a new one to get them done so i dont have to deal with them. And also is this engine a good deal or is there somewhere else i can get a better deal or anything. So if anyone could give me some help it would be greatly appriciated .

Thanks,
Ryan

most people beckon not to go for the ST205 engine because of how hard it would be to get new parts for it, blah blah...
Since you probably dont have a GT4 front end conversion, the Top Mount Intercooler might not fit., so FMIC is en route, or a conversion

anything else can be found in the search, im like 90% sure
