The hard part is redoing the fuel system for a high pressure setup and control system for the injectors. You'd still have to make some kind of cold air box though.

What he said,
I have a student here who is building up a motor as part of his training and he is running it with Weber style IDA induction (due to restrictive gay laws for young people when they first get their licence!).
He has done it expe3nsive though with a Motec M600 and 13B-REW street port, the application is the same though to your 12A.
A simple conversion can be done using all late model 13B-REW or Cosmo intake system and fuel lines, injectors etc with a simple adaptor plate to the motor. Seen this set up (will host video on my site) of a 160+mph 8 second RX3, when I was consulting for them and supply exploding ceramic apex seals LOL.
There are many ways you can do it.
Probably the adaptor plate is best.
Seen this in a speedway car running NA 13B-REW intake, and cheap Haltech ECU, all you need is a lift pump, surge tank and high pressure pump, adapotor and 13B Turbo intake system and away you go. The Speedway engine 13B made 280bhp 'bridge ported' on the engine dyno so those intakes are not restrictive at all.
