hondata+450cc dsm's+walbro 255lph hp+10psi+b16+88 crx si= 26mpg and one hell of a quick ride. I just wish I'd have checked that the motor was healthy first, bad rings and boost don't mix.

your 5-7 is no problem on a stock motor, just make sure your fuel pump can put out enough, your injectors will need a bump in size, and fuel management is the only way to go. listen to mtber he always has good advice.
