I dont know exactly of the problems getting the ca in yet but theres heaps of info on it on ppl doing it. As far as ive worked out so far its basicly just a small trans tunnel mod for the shifter and a new cross member which maddat make. They can actually make everything ul need for the conversion which isnt much needed. Hardest bit will be wiring i think. The ca would be a far better motor and easy for bits for prob similar sorta money since even with the l series motor ul need 2 do brakes and driveline. My cars the same as urs so if u go that route we can work together and discuss problems through the build.
