Questions and Answers.

The Stumpy Skyline box fits in the manual tunnel, but you might need to remove the old Gearbox mount lugs in the tunnel. This is based on Mikali's install in his coupe. I know that with an Auto tunnel there are no mods required, and you can even use the Automatic gearbox mounts on the body.

With the Stumpy Skyline box, the shifter comes up directly in the middle of the hole.

The CA18DET gearbox is definitely stronger/smoother shifting. But is longer, and involves the fabrication of a box section and moving the shifter back 20 cms (no good for a ute).

My car hasn't bent any chassis rails yet. A roll cage would help. So I may get a roll cage made up eventually.
