I've read from many places that it works. So many, in fact, I believe it.
What I haven't read too much on is the combustion chamber size and the resulting C/R. My best guess is the heads are closely related to WRX ej20g heads and would have the same chamber size. Close but not the exact same, as the SVX has only one cam pully and transfers rotation to the second cam with a gear inside the cam covers. Best would be to have one measured.

Soooo I have some info on why you don't need to do this. The lead tech at the dealership I work at went to subaru school...in japan. While he was there, he was allowed to view a VERY special car. It is a 1994 svx with a ej33TT. They only made ONE, however every other 3.3 svx motor was built with identical internals. That motor was made to take boost. had they sold a few thousand more cars, they WOULD have. but they didn't and due to the sucess of the flat four turbo, they didnt feel it necesary to release a flat six turbo. I believe the CR is so high because of the combustion chamber design.
Just a little gem of knowledge straight from japan. I need to scan the polaroid he has of the engine bay.
