Considering what they were able to do with the GT4 Supra, I'm hoping we could see some of the results from that program feed back into the street car, particularly engine tuning. Some sort of factory 'GR tune' that gives crazy power would be really coolWhat a shame. The B58 is such a great engine. Modify the dang thing!
Race cars tend to use the smallest and lightest engine configuration possible especially in a heavily BOP class like GT3. If given the choice between V6 and V8 most teams will go for the V6. If I4 does the job they will go with an I4.
You mean Honda or Nissan, Hyundai have never participated in GT3.That doesn't seem to be the case for Ferrari, Porsche, BMW (for the longest time), Mercedes, and almost everyone else that isn't Honda or Hyundai.
