Ok, 1st of all, you can already tell by the VIN number. It should have the letters and numbers "DC2" in the vin, the 6th number is a 2. If it's a 2 door, the 6th letter in the VIN should be a 2, which states that it is a DOHC VTEC (GS-R or Type-R)If it's a 4 door, the 6th letter in the VIN should be an 8, which means that it's a DOHC VTEC gs-r or type-r.If it has a 4 or 7, it is NOT A GS-R!So inside the hood, the engine should have a black valve cover that says DOHC VTEC, and the transmission thing should read "B18C1" which is the code for a USDM GS-R.If it has a B18B1 (RS, LS, SE ,GS) ITS A FAKE!If it has a B18C5 (type-r) which is better, it's not a GS-R, but a type-r motor.Inside the car, the GS-R cluster should redline at 8k (8,000RPM), manual transmission only.Outside, the gs-r should have blades (like you stated), a badge in the rear hatch that says DOHC VTEC. Thats about all you need to know, again, check the VIN if it has a 2 or 8, 5 speed manual, 8k redline, DOHC VTEC, blades.
