The thing is everyone has different views what counts and there are so many variables in the tuning world.

Martins cossie was a fine example of what mainly still a cossie engine on evolution of the cossie engine with other custom made parts to cope with the power.

The same can be said about most RST,s i.e the zvhS zetecs

But in the same way most people wouldnt class an XR3i/XR2i with a RST engine transplant as an RS.Or if Jim fitted a cossie YB engine in his XR4i it would still be an XR.

But fitting a chevy V8 and auto box to Martins is totally altering its original charector okay it would still be a cossie but it all depends on what your own personal views of the limits are.
