It would be a conversion, no n/a 33 came out factory 5 stud.
My old n/a 33 made 123.1 rwkw not as bad as people think they are you just need to find a good one and manual.
If I did it all again (the p plates i mean) I wouldn't go skyline at all too many people have them now and half of them are wankers.
I do half regret going from N/A 33 to 33 GTR just because lets face facts they look 'similar' but I REALLY wanted to own one at some stage in my life, and after bringing it on the track / drags the $$$$ vs performance cant be beaten. Don't know any other 20k cars that run mid 12s in street trim and stock as a rock. I was taking 350rwkw XR6T with slicks on the day - he mad?
