I thought the flanges were different, in the ST185 as opposed to the ST165.
Actually both the ST185, and ST165 share the same flange, which is identical to the Supra flange, only divided. The major difference is the flange to the downpipe, which has two wastegate ports in it instead of one.
It's a really simple fix though. Remove, and swap exhaust housings. The exhaust wheels are the same size. Hell, all I did was leave the exhaust housing bolted into the car.
Tissmo: GT35R = GT3540. They're the same turbo, just different names.
GT35R is a GT3582 ball bearing. GT3540 is an unofficial name standing for a GT35 with a GT40 compressor wheel (a GT4082 wheel to be exact.) Sort of like the old T3/T4 names.
At any rate, it's an 82mm exducer wheel.
