The seals have gone in the t3 on my series one so I'm in need of a new turbo now. I assume the engine is standard but I want to breath a bit of life into it. I've heard that a 4x4 cosworth t3 is a good upgrade so was looking to buy one of them. What is the limit of the standard head gasket? Do you think it's worth fitting an uprated one for peace of mind or is there anyway of knowing if it already has an uprated one? Also I was thinking of fitting a uprated camshaft but what one would you recommend as I used to run 285t2 years ago but done a search and can't find any forsale anywhere

Thanks Billy
