The stage 4 Nissan VG30 engine heads are great for a Nissan 300zx that wants the maximum amount of power and a raised rev limit for big laggy turbos. If you are rebuilding your bottom end it is a good idea to get your heads refreshed. We have over 16+ years experience with Nissan motors and know what it takes to make power.
