I believe the ej22 heads had a 41cc combustion chamber and the ej25 51cc, so you compression should be lower than stock, i'm not sure how much lower though.

Decent base for a turbo build. Poor choice of parts for a non-turbo build......

CR should be in the 8.5:1 realm and about 115hp.

If you were going for a frankenmotor, you did it backwards.
