I am not going to debate with you on which car is the better track car, but I should be in a good position as I have both a track ready 240SX with an SR20DET that will be going to the track next week and also a Z32 that I competed in track events with. The Z32 has since been converted back to a street car. Before you start all the comparisons below, get your facts straight. A lot of 240SX are 5 lug without the Z32 rear uprights and thus do not require specially converted shocks. And btw, JIC is not the only company that can do the Z32 conversion. Do some research :My friend has an s13 with the sr20 in it. The car is stock, and needs alot of work to make it a good track car. The suspension is very expensive. If you want the Z32 5 lugs, basically your stuck with JIC coilovers. This is not totally true. You can do a 5 lug conversion without Z32 parts. That means you can use a mulititude of coilovers. I have done the Z32 on my 240SX, but I have seen others do it with other parts that does not require them to have a rear shock to use a lower Z32 mount. This is a very broad expense quote, because it depends on the quality of parts you get. If we take say my Z(converted tt) and his s13(sr20), which are both stock, to take them to healthy performance levels it would go as follows:
: Z s13
:Supension: $200-$11000 $1200-$11000
:Wheels tires: $350-$5000 $1200-$5000
:BPU: $3000-$5000 $2000-$4000
:The reason there is such a price difference, is because for most folks, the 4 lug of the s13 isn't gonna hack it. Wheel sizes are limited. So this price includes the Z32 5 lug conversion. When you do this, your stuck with JIC'S. The reason for this is that to convert the rear of the s13 to five lug you would want to go with the z32 rear hubs since theyre aluminum. The problem is that the s13 rear hub lower shock mount is a ball type while the z32 is a fork type. Knowing this you would need the rear lower shock to be replaceable so you can convert to the fork type yet keep the correct valving and spring rate for an s13. Unfortunately JIC is the only company with this feature. As for the Z, the prices are low, because you can keep the stock wheels, and upgrade tires. Or keep stock springs and upgrade shocks, and it would still have reasonable performance. You could keep stock wheels, and springs on the s13, but I don't think it would be so hot.
:When all is said and done, with both cars setup good. Its always gonna come down to the driver. But if I had a choice just off of theory, I would take the s13. It's a fun, compact car with 50/50 weight. But I love my Z, and will have fun driving both when their ready.
