No, they don't all have VTechs in them. I don't know what size engine is in your car, but there are only a few different VTechs in a few Civics, they being the 1.5L VTech, 1.6 SR model, the VTi, SIR and TypeR civics. any of the others, the 1.6 Lsi model, the 1.6 ils model. My theory is buy a VTi, SIR or TypeR Civic and then stick you're turbo in. It strikes me as a risky and costly venture to get a VTech put in a civic that doesn't have one. For starters, you've to find and buy VTech, get it installed, that could take a while, and then get your engine management readjusted to suit the running of the VTech. Hopefully thats some help to you
