Message no, nobody makes the gears to fit in the diff for the ZTT. If you can find a place to do it, you can probably make them a lot of $. I had a diff to try and do this with, but gave up and just dropped it off with Greg Dupree if I rmeember right. You can keep the TT suspension if you swap out the bearings with a press and do some small mods to where the HICAS was hooked to. You'll still have to swap the subframe though.
The reasons are:
1)The NA diff is completely different and much lighter, it won't bolt into the TT subframe and would take a lot of mods to get it to. Therefor you have to use the NA subframe.
2)The TT shafts won't bolt to the NA diff, so you have to use NA shafts.
3)The NA shafts are a smaller diameter and won't fit correctly into the rear wheel hubs, so you hvae to use NA's.
4)The shock mounts to the assembly higher on the NA, so you have to use NA springs or the rear will be up almost an inch higher.
