Hello, will the PowerFC for 'SW20 gen2' fit the '5/1991 ST185 GT4' plug and play?
or what must be changed?
my st185 is not CS or RC, its an ATA intercooler 1991 ST185, and the PowerFC who i want buy is one for SW20 gen2.
thank you.

Its not plug and play but almost

You will need

Rev3 Mr2 turbo Igniter ( just plug in )
Rev3 Mr2 turbo Map sensor ( just plug in )
Rev3 Mr2 turbo MAT sensor (needs wires soldered in)
Rev3 Mr2 turbo IAT sensor (needs wires soldered in)

(ideally also 550cc injectors) it will run really lean until mapped if you stick with the 440s ( you can up the presure in rail if you need to drive to mapper/tuner. though and take it steady no boost)

you will need to repin the engine harness, and ditch the AFM. All very easy really some guides online search for rev2 to rev3 ecu conversion on mr2 boards. If your ok with electronics (basic) and a soldering iron its simples. im in the process of doing it now but im using a st205 ecu for now.

May you can get a hold of CRW (Chicoraceworks) I know they can do some work to the power fc to have it work on 5th gen Celi or it might be ATS
