I may be swapping my motor to another car, so I figured why take out the trans, but it is easier that way so I guess that's what I'm gonna do. Before any motor goes in any car it's gonna get a HG and ARPs, and I'm probably gonna NA-T. IF I keep my auto setup (I'd like to), what can the A3040 handle HP wise?supramacist said:I was taught that you pulled the entire unit. If it were myself..., I would pull the trans and all. It's going to be easier to set up and put back in. Instead of pulling the engine, inserting the engine and then reconnecting.
