G16b from a baleno is plentiful and imo look the neatest.
I have a vit g16b in one and a baleno in the other.
The baleno is a much neater finished product (pic borrowed from DiscoS' build thread) and clears the bonnet better.

The intake hose from megazip fits the stock airbox in the factory position.
It was just over $100 for the intake pipe, and plastic adapter to remove the warm air intake valve.
The above includes a jimny intake manifold and extractors.
I need to finish off tidying up the wiring on mine now it's finished, but ill post a pic if I remember.
I used the baleno intake manifold, exhaust manifold and ran the radiator hose under the intake (I made my own passenger side engine mount).
An 8v g16a from a vit can be done in a day.
A g16b from a baleno and vit takes a while, but is very very worth it.
