How about the cross member, a 4200 & 4L60E trans bolts right onto a stock cross member? If so, what cars will bolt right in?
Nova ,Camaros, etc.

A 4l60 will bolt in where a th350 was.. just slot the hole ~ 1/2" reuse the OEM trans mount. Google 4l60e swaps 1000's have been done.

Need to change the fuel system, have a return line?

The system needs a fuel pressure reg and a return line with an EFI pump.

What tuning software is needed to tune? None for a stock engine. When Jeremy strips the harness - he does a "emission delete + a mild tune" its all included in the harness price.

How much for the software, or for someone to program it? See above

How much boost pressure can the stock intake manifold before it comes apart?. I have ran 10 PSI no problem, the I5 (3500/3700 colorado) guys have run 30 psi.

The LS intake plastic manifolds come apart after little boost pressure is applied.

Is the stock exhaust manifold a good design to add a turbocharger? Yes 95% of the turbo installs are using a U up pipe and the stock exhaust manifold.

If not, how much is a turbo exhaust manifold? < not required unless your going after huge power.
