RE: Toyota Celica GT4 ST185 Group A
you on toymods or ozcelica? pro more info there from owner etc.
the grpA st185's had WTA intercooler systems, steelwheeled turbo's, bigger airboxes/AFM's, all widebody, more agressive front bumber and vented(not scooped) bonnet, and the ecu has map's for 16psi i think.
still heavy cars and 230ps, the grpA will always have more value than the lower gt4 versions esp if kept in good original cond.
they may have had diff gear ratio's as well. i know there was a rallye version with close ratio but not sure if the grpA got them as well.
still have the same draw back's as the gen2 3sgte sw20's.
