What\\\'s The best Swap On A Budget for a 1990 Honda Civic Si(4-speed)
 

I just bought a 1990 honda civic si, and it runs good. i check my stats and instead of getting the engine rebuilt, i rather just swap out for something better. I\'m also new to the honda club(this is my 1st Honda and 1st stick, and I LOVE IT). I also wanna swap my 4 speed for a 5 speed. So should I do both swaps at the same time? I need help asap,cause i gotta get it running nice and fast by the end of the summer. thanks 4 tha help

it\'s a D16A16, 1.6L 16V SOHC
