sounds risky, but you should boost it low, alot of mivec + turbo doesnt ends up well.....do some research and u realize alot mivec turbo blown their engine due to the hard tune Mivec system and the turbo.
NA Mivec and those factory Mivec Turbo in Evolutions nowadays, the engine is totally different. DOnt blow your self.
