No, the Honda Civic springs is not compatible with any generation of the Honda Prelude.
The 1989 Honda Prelude had 4x100mm offset. The 1989 Nissan 240sx has a 4x114.3mm offset...so, it will not fit.
Yes
No. The 1989 Prelude's body style is different, and a little larger, than the 1984 body style.
Yes, but it will require a large amount of customization.
No. The Civic seat rails are different.
No. The Prelude has a B20A5 motor. The civic will have a D-series tranny. They will not interchange (B and D series parts do not interchange).
yes
No.
No it will not. It can fit, but you will need head lights, fenders, hood, grill, and front bumper from a 1999-2000 Civic. Transmission doesnt matter.
Unless you get some custom mounts made, the civic engine will not mount in the accord. Any 92-96 Accord or 92-01 Prelude engine will bolt up to the 92 accord. **Note, the 97+ Prelude engine is OBD2, but can be converted back to OBD1, which is what the Accord is..
NO, they have two completely different motors.
