-->1 month and 2 weeks later<--
After 2 weeks of searching craigslist I found a RB26DE for the S13 and this is how it looks like:
It will get a turbo kit as soon as it arrives here. The guy from the junkyard called me and he got 2 S13 in: A blue one that got rolled and a black one that has a smashed front end. Unfortunately the lights were gone and the glass was smashed, too. The blue one had some recaros in it but they were worn as hell and are in an upholstery right now.
