Motronic, Carbs or Aftermarket EFI
My 66 GTV has a twin spark installed, complete with standard motronic and air plenum.
I recently installed a squadra tuning chip which seemed quite worthwhile, with better drivability.
However, the large standard air plenum is starting to offend ,me, there is marginal access to the fusebox, and despite adjusting it still hits the wing a little. The inner wing was slightly modified by the previous owner to accommodate this.
Anyway, clearly the best way is to go for ITB's and aftermarket engine management.
However, this would seem to cost the thick end of £4000 to do properly.
I keep on telling myself that carbs would be a step back, but in reality, will they?
I love the throttle response of other carb cars I have driven, and I know that they will sound better than the stock setup.
If I go for mapped ignition then its seems like for circa £2K I can have a clean, neat and nice sounding installation?I do like the idea of going to coil packs and away from the single dizzy I currently run.
Presumably MPG would be not quite as good, but I could live with that.
At the moment the engine runs standard VVT intake cam, and has no mods apart from the alfaholics exhaust system.
If I go carbs, does it have to be 45's for a stock engine? I have the original 1600 engine 40's, which I could get rebuilt and re-jetted.
This is a very common engine swap, can people share their experiences as to what works best??
