I just posted under the forced induction/nitrous in are there any other turboed Elantras out there, what you need to turbo an elantra, sonata, your's is basically the same but where on the old school elantras and sonatas that came with the 4g67,and 4g63 motors the turbo manifolds form Eclipses,Talons, and Lasers just bolt up to our motors. I your case you need to have a Custom made turbo manifold made to fit the car and the turbo.
And everything else is the same. Hope I've helped you out if not feel free to asking Questions.
