I agree with samsung z and piotr. still being 16 you got alot of time on your hands to build before things like paying rent and things in that notion come along as well. if i were you i would go look for a good running N/A and buy that just to daily around. do some mods here and there but nothing to fancy or over the top. and then just save up for a TT motor to build so that way you have a car to drive around and then a motor to mess around with while its out of a Z's cramped engine bay. then once its ready, drop it in and enjoy the ride.
