Yes you can upgrade to the 3.0 engine. I wouldn't recommend upgrading to an HPI engine again though. I would say try out an OS engine. They make great engines for a great price.
I am not familiar with the original RS4 layout, but if it has a layout similar to the newer RS4's with two speeds, then chances are you can upgrade to it. It may take more than changing the spur gear though.

It's the same chassis as the new rs4 it's just a single speed

You may be able to by buying all the transmission parts for the 2-speed. Let us know how it goes.
