Are they the same?

[Kranz]

Thanks for all of the good info guys this help me a lot. Also is the NTs 4g63 the same from 90 to 94 right? Also if I wanted to use a NTs and turbo it and put more boost to it than stock is to change the pistons and use a turbo head gasket right? and swap cams. I would keep the turbo block and build it up and run a NTs for the time being. also any more tips or do and don't would be great and greatly appreciated.
