I'm back again.

[turbo_skylane]

I have finally re-installed Flight Sim after along time, I had computer issuse on top of computer issues. And I had over time lost interest. But, a friend got me back in after talking about the skins that he had made for a couple of Boeings. So, I decided to get back into it. I vaguely(sp?) remeber some mods I had done before for '04. Does anyone have any photos or an acutally plane? (I remeber posting a trial plane in the FS04 section, anyone have it?) Im surprised I remebered my username. So i decided to start back into it with a Piper J3 Cub. Customized, 'Hot Rodded'. I've read about a Piper Super Cub. I am trying to adapt the specs of the Super Cub into a J3. I have a few issues. How can I find/calculate cubic inches per cylinder? Or am I better off trying to find engine specs for a Super Cub. (which I havent yet). Also, I am wondering if there are any modifications availble for planes like there are like for cars, such as exhausts, turbos/superchargers etc? If there is any name brands? Because I would like for my Super J3 to be a bit faster, and almost race plane like.
I am not sure what forum to post this in, it has a bit of Flight sim and Real aviation in it, so I figured general would be best.  ???
