Need advice for 370z mainly track

ytian9

Hi, I am new here, I just want to get a 370z for track use as i have other cars for daily.
Just purchased a 09 GTM twin turbo 370z 3 months ago. I didn't have a chance to drive it yet. And I don't have dyno sheet, don't know how much power it produce. I just saw someone is selling one with tasteful modified 2015 370z for a really good price(just modified last year) . I will post the modification list of both cars.
My questions are:
1, is the 09 TT okay for track? Is the motor going to blow if i do heavy track use.

2, should I get the 2015 and sell the 09 TT. (Worrying about motor blow, as i never drive turbo car before)

3, Should I get the 2015, remove all the modification parts except intake, header and exhaust, and then put on 09 TT. Put back stock parts on 2015. Then sell the 2015 one. (Almost free parts from 2015)

4, if i am going route no.3, should I just get differential cover, solid motor Mount and all necessary solid bushing(control arm bushings, what else do i need to change?).

My friend running a used car dealership, so i am not worried about taxes or other things.

Thanks
