Not really a crap engine - just an older model that has been superceded over the last 2 to 2.5 years. I started racing with a Gen 4 7 Port in my buggy, and it was a very strong motor in it's day. The new GX Series are a Gen 5.5 model, so lots of things have been addressed over that time and improvements made like any other brand out there.
To be brutally honest - I would re-sell the Gen 4 and get a new GX-7R. Will cost you less than upgrading the old motor providing you can sell it on, plus you won't have that looooooong run-in time of the Gen 4
