i may be building my 240 to the redline time attack street tire class rules and i wanted to ask if anyone here would know before i call around to find out this answer.
"4-1.1 Engine upgrades are allowed within the same make and model, i.e. Honda B to Honda K or Subaru 2.0 to Subaru 2.5"
my question is can i use the sr20 in my car being that its still the s13 chassis but technically a different model/name or do i have to stick with the ka because it was the only engine availble in the US model. and technically the only USDM sr20 was in a completly different model
