internal engine mods are free

So you can do whatever the budget allows. You can't turbo or fuel inject a car unless it came that way from the factory, so it is strange about the Gemini
You are allowed to use flares from a 'recognised production model' so it's only the factory flares for my car, but I have seen pics of some of those massive flares you're talking about in these Nostalgic Hero mags.
The GTR's standard wheels are 14", it's the width I can't find anywhere. 175HR14 was the standard tyre. They came with steelies as most of the GTR's ended up on the track. The Aus 240K had a 5.5" wheel, but I'm hoping the GTR had a 6" wheel so I can use 8" width. I've measured up the wheels I want, and they will fit under the GTR flares - In Japan it's not unusual to see 9.5" or bigger on the rear of these things!
Not much to see with my car just yet, I'm just gathering info and parts at the moment, and I want to get some repo GTR parts like grill and some badges from Japan. but
here's a pic of it when I first picked it up with the dodgy flares and V8 complete with bonnet scoop

I'm having a few weeks off in August to strip and paint it, so I'll get some more pics after that.
Targa rules can be pretty complicated in some areas and being an international event I guess the scrutineers have to check eligibility quite strictly, so it's not really surprising they've gained that kind of reputation. Targa NZ have much more open rules though, and we're thinking about doing that one next year in the 1200.
