For the intake I used the standard 4AGZE one, but hacked it of 40mm from the head, and then bought and shaped alu pipe and plate 'till the manifold was completed held together with masking tape. I then took it for welding. The turbo manifold I completely built myself.

efi manifold
flanges - free, original manifold hacked off
pipe main plenum 60ZAR = 8.83AUD
TB flange - free offcut
sheet - free offcuts they had lying around
fuelrail, fittings - free, original
4x injectors 365 - free, original
welding - 300ZAR = 44.11AUD

total 360ZAR = 52.94AUD

turbo manifold
flanges 120ZAR = 17.62AUD
studs, nuts etc = free have lots of bolts and thing horded so used that
steampipe and bends 150ZAR = 22.11AUD
welding = free did it myself, ok add for electricity 20ZAR = 2.95AUD

total 290ZAR = 42.68AUD

Now take into account that I tried to source ready made parts. They wanted to charge me

EFI manifold 2500ZAR = 367.65AUD
Turbo manifold 1600ZAR = 234.96AUD
