Apologies if this is the wrong section or if this has already been asked a million times but...
I'm coming towards the end (i think) of my rebuild where i have transferred the engine (1990 -998 on SU carb), interior and running gear from my old rotten shell into a newer shell (1993 MPI, currently listed as a 1275cc). i took the car the for a pre MOT inspection and i was told because i have a newer shell on an older engine i will need to either fit a catalytic converter or demonstrate to the garage that it does not require a cat.
My intention is to update the DVLA records but was also wondering how i get around the whole cat situation? I assummed that a catalytic converter and carb don't really mix? Any advice would be hugely appreciated!
