I didn't check the link yet...
I think that with your ProECM chip and the addition of a S-AFC and/or FPR, you could run the 2.5 on a 1.8 ECU. Of course you'll need an A/F gauge to monitor the mix but it should run with no problems. You may not make all the HP of an OEM 2.5 because of timing tables, but the chip can alter that. It'll take more tuning to get right then leave it alone.
I also plan on doing a 2.5 swap into my AWD 1.8. All the restrictive parts on the 1.8 can be switched over to 2.5 parts astime and money allows. It'd just be like adding mods.
I say go for the swap. Stay N/A for reliability if you like. Conservative boost levels are proven to be pretty reliable too as Chad is showing so don't count out a simple add-on turbo to your 1.8.
Now I'll go check the link and edit my post as necessary....
