i would be inclinded not to use the standard crossmember and mounts m8.even medium power cossie turbo will rip the mounts to bits imo.if you do wrap the o's mount in heat wrap as that will melt it and it will brake even quicker.you can use the rs2000 sump if you get the oil return put in to the sump for the turbo oil pipe.smithy still uses all standard stuff in his mk1 before he stripped it fo r the rebuild
