Sounds interesting rikki :
You have maf, tps, cam/crank, cts, neutral and speed sensors
 
Note that your 97 is non standard odb so you cant use regular cheap chinese bluetooth odb reader Rikki

i bin doing some reading and the way it reads is that thery are backwords compateball using a attapeter but not 100% is this right
 
somthing like that obd box to pie runing the app then to a micro sd card or wifi dont no yet to a sever so when i pall up in the drive the dater go to my pc
 
That question I cannot answer, a quick websearch turned up nothing much - you can get obd I + OBD II machines so it may be a coding issue.

as far as im aware I have a few of the Bluetooth and usb readers and I thought they were backwards compatible like someone else said just using an adapter, Everything should just work, Currently I have a 4.3 inch monitor built into my rear view mirror and am planning to mount my raspberry pi in the glove box so it comes on when the car starts and auto comes up with Stats about the car int he rear view mirror.. I also have a 7 inch screen that im planning to mount in the dash at some point that can be connected to the Raspberry pi or my laptop which will do similer things and produce just about any dial that I could want :)

Urm try with an app on like your smart phone or something first? plug the obd reader in and get connected up to it, Then make sure you can getting sensor data using an App like Torque. Then go from there.

There are lots of websites that offer these, But I would check your car Manual aswell as some of the more common Fault Codes should be listed in there or in the Haynes manual, That's your best bet because if your reading online there will be thousands of codes but only a tiny fraction will be for your car, So I would say to start off just use the codes that apply to your car and get those working, once that's done then start to add more generic codes that will also work with other cars.. Because in my opinion if you spend weeks and weeks adding every code going into the software you are making then it doesn't work then its pointless.

Even if you start with commands to do very simple things with your car such as reading the speed revs and fuel Level, That should at least give you proof of concept that your software works and will take much less time, Then as you start to perfect the software you can add more codes and commands to read more sensors etc :)

Start small and then get bigger :)
