Hey Snowy, maybe you have already, but having done a 34 V-spec II for targa Tas this year, you might wanna go right through the rules of mods mate. To enter a car legally as an N1, it needs to have everything to factory N1 spec. Meaning, for eg., you need to purchase a genuine 34 N1 oil cooler kit, at, wait for it.... $11,000 when we last checked!!!! P*SS OFF!! lol.... so we ran with a V-Spec II with some susp/boost/exhaust/Power FC. Came 11th with full dry weather that didn't suit us.... oh, with no brakes after lunch on day 3! lol
