Hi, this is just in my opinion, but i don't think you have an original 1990 VN GTS. because the first GTS to be produced was the VP. one model after yours. i have official HSV books with infomation on all hsv up to VT and there is no VN GTS in it.
However, its not to say that perhaps someone made a 90 model replica of a gts or that it is HSV enhanced.
and in that case that may be what u have.
you could always contact hsv with your car numbers and they can provide all the info you need.
Anyways just thought id give my opinion as ive never heard of a vn gts.
To my knowledge they started at vp.
i once owned an original VN clubsport and there were many people who argued with me that they didnt exist , yet of course they did.
does yours a build number?
anyways, good luck.
