I'd be wary due to the 1jz swap. It's going to be extra work if something ever does mess up since you don't know how the custom build was performed (especially with the twins set up). However, from what I read, the 1jz is suppose to be better than the 7m so if you can get a look at the engine and give it a hard test drive then maybe it's worth it.
