I'm getting parts together to rebuild my '87 300zx turbo. I've decided to up my compression and was originally just going to swap in NA pistons. But I will be upgrading the turbo, and increasing boost, looking for between 400-500 rwhp. So I'm going to put forged pistons in. This way I don't have to worry about them and have room to grow later if I decide I want to. I can't seem to find forged for the VG30ET. I've found an abundance of VG30DETT. What I've gathered is these will fit but due to cylinder head differences compression will be lower. Is this correct? Can I swap the z32 heads over to correct this? If not, how much is the difference? I'm lookin for around 9.5:1 cr.

Any help is appreciated. Thanks.
