Also for the sake of reliability, I would start with the newer, more rigid chassis. Lots of "small issues" plague race cars that start from older models. Its only logical as time takes its toll.

My vote also goes to the newer, more powerful Z. Do you want to spend your money getting a motor swap or making the car faster around the track?

Not to mention that N/A cars are more reliable and are less prone to overheat. Not to mention they have a flatter torque curve. Less moving parts to break. Better response.

Don't forget the Z is making 315whp with simple bolt on's. The 240 wont make that without bigger turbo which will be more $. By adding the bigger turbo you add lag and lower reliability even more. Then you will worry about your new used motor blowing up.

The 240 may be lighter...but once you add the hardware to make any decent power not only is part of your track budget gone, but the weight difference has been cut.

Then you need to add decent brakes for the track, BBK's arent cheap. More of your budget is gone and the weight difference goes down even more.

Assuming you dont run into any maintenance issues (highly highly unlikely when doing a motor swap on a used car with a used motor), you will still end up with an inferior car 10k in.

Not even close...

10k in the 370 = 315whp NA, coilovers, swaybars, wheels, tires, oil cooler, camber control arm kits, brake pads, rotors, fluid and lines, diff.
10k in the 240 = headache.
