You can have an expensive build or a not quite as expensive build.
You have to have it in your head exactly what you want and expect.
Have you the tools and time to build your own bits?
I have used a low km's LS1, used AU XR8 rear, I refurbished the front end and rebuilt the brakes (sh#t I hope I did them properly) and generally been pretty tight as far as farming jobs out.
I am not going to get too exited about the underbody finish of the car as I am intending on driving it to death.
I will however get sombody to paint it for me.
All up it will probably set me back 40-50k before I start hot rodding it.
The beauty of building yourself is you do what you can afford at the time.
As most everyone pics up I am yet to buy shocks, not becuase I have forgotten or are starting a trend but becuase there are better shiney things to buy
