Well, if you guys are feeling really ambitious and aren't limited to body parts:
A TVS or twin-screw blower kit, possibly with a nice laminova A2W IC system, big double pass HE and stout water pump. Or, I suppose, non-intercooled but with a progressive W/I system.
To keep costs down, fuel pump, injectors (with some recommendations on sizes/models maybe), and tuning could be on the end-user to sort out.
Will also need a new FG (or CF) hood to fit, I suspect....
V8 grunt without a swap
