i did my EG3 convert to jdm b18c vtir 4 years ago in perth, being in perth means expensive labour and parts.
just did my turbo installed awaiting for the tune.

price break down:

car itself when i bought it 4 years ago: 5000
half cuts: 4400
fuel tank, fuel line and EFi dash: 600
b swap with fixing clutch master cylinder and using dc2 half cut front brake: 3000
suspension Tein HA 2nd hand: 800
brake pads EBC red: ~200
rear drum to disc brake convert: 600
bigger wheels 17" and Toyo tyres 205/40/17: 1000 + 1000
turbo kits (including intercooler, BOV, injectors, oil line, manifold, T3/T4 turbo, fuel pump and waste gate): 4000
installation (custom scream pipe and dump pipe, water line): 2100
PowerFC: 600
tune: 550
some bucket seats, half cage, steering wheels, carbon filber bonnet, spoiler, lips: 2500
so total: $26 350

having said that, i think eastern state is much much cheaper.
i am still waiting for the tune this weekend after the turbo installed.

thats a lot of money, but there are more to be done.
