I have a soft spot for Nissan's S series cars. Having previously owned a s13 silvia and 180, both SR20DET's. They are great little cars to drive, great handling and good responsiveness to mods. A swap to a T28 BB from a JDM s15, Eprom,FMIC running 15psi can safely net 190-200RWKW. Thats great in a 1200kg car. Add a Disco potato,PFC and z32 AFM and u got another 40RWKW . Compared to my 33 GTR they are pretty fuel efficient. In terms of practicality the 180 is better with the lift back, and if u wanna do some dori dori, u can fit more tires/equipment in the back. Go a Type X.
