Celica Forums General Discussion Engine and Performance Piggyback or Stand alone ECU

Hello,
Completely new to the Celica as I was recently left/inherited a 1995 Celica GT. I've read through multiple forums and threads, called local import mods shops in Missouri and still having trouble finding what current piggyback or stand alone ECU to utilize (if possible).
Looking to just turbo (CT26) the 5SFE engine and try to keep it original as possible, besides the turbo, intercooler, injectors, exhaust, etc. Anyone have a suggestion on what can be used for a piggyback or stand alone ECU?

Thanks in advance
