Ls/vtec & Crv/Vtec are both a waste of money "i think"... to build a Ls/vtec or Crv/Vtec it will cost about 5000.00 dollars to do it the correct way... And to only be at roughly 180-23o wheelhorsepower after dropping 5000 into the car is just a major dissapointment... I say do Ls/Turbo... you will thank yourself more then enough in the long run....
