Rb25 engine and gearbox swap 180sx

[Jackabo]

Hey guys I’m just wondering how to rb25 engine and gear box swap a 180sx I’ve currently got a rb20 gearbox in the car with a 25 sitting in front of it (also using a r32 engine cross member) but had a change of heard for power numbers and now I’m wondering how I can fit the 25 gearbox but no one online seems to give clear description on how to do it

unbolt rb20 box put in 25 box, weld metal tabs to extend gearbox mount so all 4 bolts line up, get new tail shaft to suit gearbox & length.

Exactly how I did mine 11 years ago.......
