Nismo made 300 (think they only ended up makeing 276) homologation cars for a race series.
Using the JDM 2007/8 z33 Nismo chassis which had some extra welding to strengthen the chassis, a load of nismo parts to it , bodywork, suspension, exhaust. They then added a 3.8L forged engine making 350bhp (detuned for the road cars ). The race cars were 400bhp.
I now buy these instead of paying into a pension 🤣
