weekend warrior was one of the packages gwerks offered. bit tough as gwerks are no more the guy Darren ive just had a chat with managed to find a number for him, he basically said that it would of have been ported and polished ect by jp at jnl racing to a race spec as I haven't spoken to him for 4 years and the call was out of the blue he said for me to give him a call Monday and he will have a look for the paper work but after jigging his memory he remembers the job he has said to take pictures of it but as I have said im no mechanic and wouldnt know where to start with that. perhaps other fellas on here may know what the package intailed but I guess its all a bit bespoke. hang tight and see what info I can get Monday.
