Does anyone know if the 94 Integra sub frame is the same as the 92-95 Civic Sub Frame?

 

Yes they are the same for the power steering equipped cars.

 

Yes they are for power power steering equipped cars as stated, the Integra does however come with an extra brace running across it (this can be unbolted and bolted to a civic subframe, the threaded holes are there for it)

You can see the extra brace here:

 

Thanks
