I was told it had come from a GSR (uk) and set it aside to use with my coupe build when I started putting it together, when it can to fitting it I found that the torque mount has a different bolt pattern to what I have seen before.

The make on it says its a Y21, do you think this might be a UK B18 gearbox??? or not a B18 at all???
