I have a 240sx with an sr20 and hate 240's so Im looking at getting a roadster and swapping the stuff from the 240 to the roadster and then parting out the 240. Is there a write-up on how to? Whats needed, etc...? Ive done swaps before and have mechanical and fabrication skills but just wanting to know like what rear end can you use? Can you use the stock roadster rear end with a custom driveshaft or do I need to swap out the pumpkin and rear axles, etc... Anybody have experience with whats involved? Thanks.
