Hey I did a little searching around in some other places and was able to find this:
MIVEC EVO Motor


Boosted 420A


So far from what I have read up on, a lot of people are "speculating" that because the mounts are located relatively in close proximity to each other in the engine bays that it might be an easy swap. However 2 things are being heavily discussed, 1 is will the Evo motor be easy to turn over, tune and run well in a 2gnt due to the ECU and fuel mapping differences and 2, Since the MIVEC is a SOHC and the 2gnt 420A's are a 16 valve DOHC, are there any other, less financially challenging options to make it work.

Long story short:
Can an EVO motor fit and work in 2gnt = Still speculating
Is tuning it easy = Who knows at this point
Will the EVO motor work with a DOHC = See answer above.

I hope this helps out a little at least. I know I am waiting to see how this can turn out also.
