Ooh not a good sign , that car lined up very well when i had it . Atleast it has adjustable arms under it . Turbo choice for a 20 is fairly simple but most people stuff around with other things that don't need to be , best results from rb20 are with simple setups, i.e , a good exhaust manifold , cam gears , cooler , pump , injectors and a decent tuner . Most people try to put too big of a turbo on them and they just can't flow enough air to keep them on full boost , td05 16g would be too small for track , i would predict near stock response with similar power to a standard r33 turbo , maybe a little bit more , more suited to a ca18 really , td06 would be slightly laggy for street but days of fun on the track
