yeah they only came with the 1.8 liter CA18DET and CA18 while the model was very young......... most of them (1990-1998?1999?) had SR series motors...

Although I'd love to see a pie graph showing what percentage of ALL S13's were made with KA, SR, and CA... I have a feeling that KA motors would be king, I dont see them selling more S13 chassis's in japan than here in america (despite our shit motor)
