Introduced 1988 in three body styles - the coupe (Silvia), hatch (180SX) and convertible version. S13s produced from 1988 to mid 1991 were CA18 powered which unfortunately came under constant critism about the drop in power from the S12's FJ20DET (142kW) to the new CA18DET (130kW). This is not to say that the CA18's weren't bloody quick! On the upside however, the new S13 won numerous awards in Japan due to its high level of technology and innovation such as Nissan's HICAS four wheel steering which is still used on cars such as the Silvia and GT-R to date.
But Nissan decided to revise its forerunning 4 cylinder engine with thought of creating something less sophisticated (since the CA18 was very sophisticated in its components and thus very expensive to build!) and more powerful than the aging CA18 block.
In mid 1991, Nissan introduced the SR20 to the world which continues to lead the silvia charge today in the latest S15 model. The SR20 has been in other well known cars such as the Pulsar GTiR and the Bluebird 4WD SSS.
