Last time I look into to it. I think if you are car club member with a log book you can use the car to drive to tarmac rallies, hill climbs etc. 


Needs a current CAMS logbook and you need to hold a National Rally Licence (which requires Observed Licence Tests) and use of the vehicle is quite restricted and I think you would be hard pressed getting away with driving to a trackday or hill climb. Not certain but a CAMS approved roll cage for two occupants probably also required. Perhaps those more familiar with rally requirements can help us out here.

Change of Plans:
The last 48 hours made me realise I’m throwing this away.
This will be swapped into a registered car and then put up for sale.

If you a need a chassis to put the driveline into I know of one. It's the 89 two tone Aw11 in my garage :)
Already running an e153 rev3 box with a 3sgte. The 2gr would slot straight in! (except the exhaust)

Just kidding, good luck with the swap and subsequent sale.
