I have an 87 300ZX turbo (non W-series) and I plan to build the engine at some point next year.
I know the early VG30 heads do not flow as well as the OWO heads (VG33 engine), especially on the exhaust side. I've learned that that the OWO heads will bolt up to the VG30et block (source RedZ31.com), but I do not know if there are any other changes I need to know about before I go down that path.
Can someone point out issues with my current plan?
- VG30et block (pre W-series)
- VG33 heads (ported exhaust)
- aftermarket VG30et cams
- Adjustable VG30et cam gears
- aftermarket valves & springs
The VG33 heads have the 10mm exhaust studs, so will the stock VG30 manifolds fit with modification?
Is there anything else I need to know?
Thanks!
