I am not trying to contradict Greg here, but the way I remember the 13b getting classed was this. A couple of STAC committee members have personally seen 13b RX7s making around 181 whp. Our bogey in STL is 100hp per liter. A 2.0 liter with 200 crank should be around 170-180whp. The 13b was set at the 2.0l weight plus the RWD adder. Anyone that feels this weight is in appropriate please send some data and a letter and we will look at it. I actually think that either an RX7 or Miata with a 13b in STL will be competitive.
