Gsr was stronger but was very underpowered until I changed turbo cams and engine management then same problem as gc8 gearboxes let go .Went through a couple unlike wrx 5 speeds that usually do second gear input shafts or drive shafts the gsr box didnt like hard launches in first .I ended up doing an evo 3 motor and box in it before I sold it which made it a different car. Much better but I got out of it and into subarus and nissans due to price and availability of parts . Gsr was alot more chuckable handing wise but finding an early one in good nick is really hard these days.
