I'd suggest you think about doing the 1.8t coil/PSO swap ala Dave 
Forgie.  This involves getting rid of the OEM AAN ignition setup and 
swapping in coils and integral PSOs for the 1.8t engine.  Dave has 
designed a wiring harness to accomplish this or there are a couple of 
commercial harnesses available which will also do the job (at more expense)
