There is NO car that you can pikey that lot off of in a scrap yard as the controllers are built into the ECU and they have no gauge.
You can get a sensor off certains cars, but thats the cheap bit anyway.
You are looking at 200 quid or so for a cheap setup.
and a laptop

Depends on the wideband for that, all the ones ive had will work without one, but yes definately better to have one for datalogging etc if its as a tuning aid, but I dont get the impression thats what he is after.
