I think 25K gets it done if he does the work himself. 15K is unlikely if you do a quality build. I figure you will have 3-4K in suspension, 8-10 in engine and supporting parts, another 2-3 in transmission and clutch, and 3-4K in body, as the brand new fiberglass hood and hatch will be about 1K with shipping. Primer, base and clear will run 1-2K. You will have consumables and extras (oil, sandpapers, shop supplies, extra tools) for another 1K. Brakes, wheels, and tires... 2-3K I guess, maybe more depending on what you go with.
So,
on the low end...
3+8+2+3+1+2 = 19K minimum, assuming you do all the work yourself. This won't get done in a year unless you are a hermit who lives alone. Figure in at least 2 years of your weekends. Probably more.
I hope I don't spend 8-10k on an engine, unless I start from scratch or go new 5.0. I have a GT-40xe crate motor, I figure a rebuild, a little head work, some pistons, oil pump, upgraded crank/components would be the minimum. In the process, I would upgrade the necessary components (same or lower compression, injectors and mass air) to handle a supercharger or go higher compression. Either way, I would be relying on a tko-600, steel bellhousing, aluminum driveshaft and aftermarket rear components I already have. The rear components would be the first of the drivetrain to see mods. I'm also not building a showcar, I'm all about practical. So you can cut out about 1k worth of chrome. Unless the brakes I choose don't fit, one of the last things will also be wheels, I have 16" ponies (white, from 7-up mustang) with Fuzion ZRi tires, they perform really well and the contrast is nice on a black car.
Hermit? Just the opposite, when I start this build, I can expect to have help. Even if not, I swapped the drivetrain single-handed in 3 days. (military work-ethic)
I'm not trying to argue every upgrade, rather point out that restoring/reinforcing the chassis is the primary goal and I have a lot to work with elsewhere.
