As far as recording from the MR2 is concerned you need a decent mic setup. I run a Panasonci NGS-75 triple lens camcorder but with 2 remote mics. The stock camera mic just pics up all the road noise when i tape it with masking tape to the top of the centre console :(
You can buy a splitter that plugs into the mic remote on the camera and then run two remote mics (like they use for doing presentations) and run one and mount it on the engine lid over the filter and run another down to the boot and mount the mic on the rear grill to get the exhaust note.
Here's when i did it on my auto (yes i know it sounds shit cos it's an auto!!!) but you'll get the idea:
