all i can say is unless you got the knowledge to do it yourself, i personally wouldnt bother.. as much fun as it is, its worth just as much as what a lot of vz's would be worth now....
i think it cost me about 5-6k all up to do it, and thats all labour by myself,
and that all stemmed from a $1500 conversion kit....
add clutch, at the time i paid about 1600, they were about 2300 retail then, not sure if theyve come down in price much yet.
i had to buy a tailsahft, near 900 bucks from holden trade.
i ended up finding out my selector mechanism was faulty, that was another 300 odd,
+ you will need to program it at holden,
idealy to get it to work properly, you need to drop a 190kw motor and manual box into it.
you need to program the ecm with a ute or a sedan vin number. each has problems.
1. if you do ute, your fuel guage wont work properly because its got a smaller tank
2. if you use a sedan, variable valve timing wont work unless you put a dual vvt motor in (i.e 190kw) to use a sedan program with the 175kw you then need vcm suite to change the dtc's to read active but not displayed
