    ay fellas just a few questions, about my v6 vz 175

    will a vt/vx diff fit a vz?

    has anyone fitted a larger throttle body to a vz? does it have the same kick a vx does? or just a waste? can u swap the 190 manifold over to the 175? or to much work?

    thanxs scott

    are u talking about the intake manifold? because i think the 190 and the 175's are the same. As for the diff, i think you just need to change the tailshaft because the vz's are different to the vt/vx. not 100% but just what i have been told.

    both m8 if i put a 70mm how will the vz go? and can i put the 190 manifold on the 175?. i just cant find a vz diff for sale so i was wondering if the vx will fit, but i will keep a look out for the vz diff

    alloytec throttle body is already 70mm mate. no you can't fit the variable intake manifold to the 175kw motor. as for the diff no idea.

    monaro is right, ^^^ the diff you can use one, you need to either change the tail shaft or change the bolt up flange that suit unis to the rubber uni flange, fyi keeping the rubber unis would be a better option

    what a happened to not modding this one? lol. I think the VZ has 2.9's or somthing crap like that in em. even 3.45's would be a good up grade to get some low down tourqe.
