if you where using some form of programable fuel inj ie. megasquirt you would need to program in fueling and ign timings any way. so apart from changing seals and hoses that you may have not fitted in your build and going for bigger injectors that you probably havent got in the first place
theres not that much modification to do
be no diffrent if you where using a post 95 motor as some form of closed loop fuel inj and a cat would ned to be used.
that was my idea anyway
