Hussein, if you would like to run a standalone EMS just register your vehicle in South Dakota. My wife's car is registered there and we just pay an annual fee for the sticker. No inspections, no emissions, nothing.
When we registered the yellow in South Dakota, for the title registration and plates it was just under $100. I think it's $30 or so a year for the sticker, check it out.
I have both short and long term goals, and as we all know life gets in the way. parts I currently have (and not on car): DO88 radiator, intercooler w/RIP kit, spare 16T for rebuild to a 20T, angle flange 3" downpipe, 320mm calipers and brakets and pads and rotors, SNABB short shift kit for M56
Short term goals: 1997 850R motor NA cams w/ M56H, 850R clutch, DO88 radiator and intercooler setup w/ RIP, 20T angle flange w/ 18psi tune, 320mm brakes with 17" TDR Pro Race 1.2s w/ Pilot Super Sports, Kalphenke Subframe bushings and shifter bushings
Long term goal: later style 2.4 T5 motor w/ N head port and polish, big boy turbo, M66D w/ Quaife, AEM V2 standalone, Kaplhenke Coilovers, Porsche BBK up front and S60R rear calipers and rotors, plenum intake manifold (if I can find a Aaron kit), tubular exhaust manifold, 3.5" downpipe with an electronic dump before cat
I'll update this later, I have a spreadsheet of everything somewhere
