first of all thanks for your advice last night ,so i got my car to a turbo specialist today,who confirmed the turbo was past it ,my next problem is i have to remove it from my car ( 92 sapphire cosworth) and just take up the turbo to be sorted,new hybrid one on the way but how on earth do you get the four bolts of the bottom removed i can hardly see them let alone get a spanner on them ,and i suppose they will be solid as well . I have disconnected every thing else just these bolts to do ,
