Just seems too long to fit on a shorter S13. To get the rear end to sit where its supposed to be, how far would the engine sit in the engine bay?
But either way, this is interesting. I live in Riverview and if you need a hand or just want to bounce some ideas, PM me.

Fliprayzin240sx, regarding the rear suspension: the cradle can be narrowed 4 inches in this case. This puts the tires out 2" further than stock, just about right for 50mm fender flares. The half shafts get shortened as well. The CV joints can take the additional angle. With a stiff suspension it will spend nearly all of its time in a narrow range of travel.
The torque tube can be shortened. The driveshafts are available in CF for about $1300. I have not asked, but I would be extremely surprised if they could not cut that tube to a requested length before assembly.
Regarding height: I have overlayed side view internal layouts of both cars. Engine location is not a problem. It may be slightly higher or lower, but not much. The rear assembly in a lowered s13 is not significantly different that a lowered c6. What may require extra work is the driveshaft tunnel, which may have to be raised. The torque tube comes from the center of the crankshaft, instead of the lower back end of a front mounted transmission. The center floor pan between the "frame rails" from the back seat cushions to the end of the trunk is coming out anyway, so if needed we can increase the size/height of the tunnel. It might be a good way to make room for a dual exhaust. No cutting happens until we verifying a square chassis, install the roll cage install, and do some seam welding and gusseting)
Project is stalled for a bit. I did pick up a pair of CF doors last month, but then the IRS hit me with a surprise $13k bill.
I will try to post the side views of the two cars.
