Newbee needs help SJ/Samurai

Hello guys! I’m new here in the forum and although I’ve already read in a bit, I still have a few questions. 1. Do I now have a SJ413 o. a samurai? In the letter stands as type key 315 The car of 02. 90 (first registration) 2. Can I pull 215/75 on the standard rims without further delay? Registered are 205/70R15 93Q ; spring suspension extension front and fender expansion are also registered. Interesting would also be larger wheels, what is possible there? 3. How is it? with the oil change intervals and which oil would he like to have? Unfortunately, I have no operating instructions and at all, it is my first car, I have only driven Mopped. I am also grateful for tips that concern the other lubricants. 4. Are there sports exhaust systems for the car, or can you get a better sound like any other? 5. How do you connect additional headlights (nebulae, main light)? Would you like to attach the headlights to the front bar. What does the TÜV or our green friends say about it? 6. Have I already read a lot about the body lift. Is there maybe someone near Dortmund who wants to miss one like this? Of course not for nothing, but I don’t have it too thick 😉 7. Has someone ever built a compressor? If yes, how and where to put the compressed air tank? 8. Are there fabric, soft doors for the car and if not, someone has a tip to make it. eln? So, that would be a first. Thank you in advance and many greetings from Dortmund Rasta
