Clutch issues? I use a GT4 celica clutch, straight off the shelf, suits the W5* series box perfectly, no changing of anything. The Gen1 engine I have in my shed also uses this same spline for input to gearbox, so I imagine its the same through all of the 3s gens?
Speaking of which, I have a heap of NA Gen 1 3sge parts (including a complete long motor in pieces needs new main bearings) sitting in my shed, a brand new PBR Clutch kit complete in box also if anyone is interested?! (Shameless plug lol)
