JS TURBO

Look at these on ebay: 111204546621 will these fit an Escort MK1?

Does anybody know anything about Janspeed turbo Capri's. How many 2.8s are left and how fast are they? I know that they did a 3 litre car as well, are there any of these cars around and how fast are they? What sort of prices would ypu expect to pay for either?
