there is not a lot of space back there. i owened an 01 zx3, you would be hard pressed to fit the 18, depends on how high you built the box. i dont know if the stock alt will hold up. the only bad thing on the motor is the alt, i smoked 3 of them just driving the car. upgrade the ground wire off of the motor. its only lke a 10 or 12ga wire off the passenger side of the motor. i ran 3/0ga over to the the shock tower. he had better get some large capacitors to feed the amp. you have at max 36" from the hatch to the back of the seat, however the seat leans to the rear so at the top you are down to 26" if i remember right.
