The first few don't really matter... im doing this right now if you have a peek at my resto, but essentially my list is...

Rear suspension
Brake and fuel lines with back brakes
fuel tank
engine loom
interior (so i can sort the internal loom out for alarm and ecu)
battery in AND ALARM ON (so some thieving twat doesn't take my nice shiny bits)
Engine, gearbox and front suspension in (in one hit). Its easier with the bumpers off.
Plug every thing in and install all underbonet jizz like heater box, wipers etc
Gear selector
Rad and intercooler
body kit, bumpers etc all back on
bleed brakes, fill up with fluids
piss about with ecu map
start.... hopefully.

Take a step back to think over all the bits you have forgotten, in my case spray the car.

Its the little details that take for ever, like im fitting studs to the hubs and getting the hubs zink coated etcetc. but i have to take a day off work to take them in, then pick them up, balancing a blue printing my bottom end is going to take a forever and then porting and rebuilding my head will probably take equally as long, not to mention having to wait for machining

Good luck buddy, cars looking good in your thread any how
