Hey well the SSS is a 2 litre right??? Well as i said to someone just before the SR is a much stronger motor!!! if it will fit u will need new engine mounts nd yes the wiring will cost more than the CA but i would go the SR over the CA anyday i had a 180sx with a CA in it. I had it for 2 months then i blew the motor up running 11psi through it!!! Is that the king of motor u want in ur car??
