A couple of months ago I decided I wanted to have a slightly bigger vehicle as my daily driver and had always liked the looks of the first generation RAV4. So yesterday I purchased my first RAV4. I found a higher mileage 96 2door AWD with a manual transmission. This met almost all of my criteria of what I wanted in a new vehicle. I am thinking about doing some modifications to it after I finish my V6 MR2 project in the next couple of weeks. I plan on lowering the car but I don't see any coilover suspension options. Does anybody know of one that is available? What are some common modifications that people do to these cars? I know the 3sge Beams and 3sgte swaps are common and I wanted to know if these can pass inspection in states that use obd2 for the inspection? If not what common engine swaps do people do that can pass obd2 inspection? I will need to register the car in North Carolina in the next year if anyone lives there and can let me know if these engines swapped in the car can pass inspection. I will be daily driving this car for a while and I know it's going to need some maintenance to freshen up some things before getting into any big mods. I have noticed a slight thud noise coming from the rear end and it may be the differential when I begin driving from a stop and a higher pitched whine coming from the differential when I'm in reverse. I'm not familiar with these cars or vehicles with AWD or 4wd. Thanks for any help that you guys can give me.
