Yeah thats true.
Yeah the guy over here did his with a toyota box IIRC. Same as the ones in supras etc. Think the 30det was out of a Cedric or Gloria. Looks like the best way to go really, although I would like to keep a nissan box in there, I'm kind of strange like that.
A car swap is the way to go, but I like my car. The blue with the aero kit is hard to come by over here in NZ
