Do you already have the car?
If so what frame are u running? (I'm from so cal home of dune buggies/sandrail been around them most of my life )
An a turbo 5.0 in most of those on the street will lift the wheel very easily. An provide horrifc handling(think of weight bias like a boat) tranny motor rear end all in the rear. Dam near no front weight at all. Just food for thought.
If u haven't built it yet I would recommend looking into the subie 2.5 ls1, northstar v8 as these are the main motors that are used an soooo soo many kids out for rails. Or u could build up a class vw motor
But there are many many companies that make full faring bodies or just panels to attach to almost all frames .
But there were a few legal ones for sale around ohio I belive u would just need to get it inspected. An pass with seatbelts, lights, mount for plate the right tires ect.
Sorry for the off topic post I think I just got a chubby ahhh I miss sand rails
