Hello and Welcome -

My name is MIKE - Im happy to help / advise you ..

Im sorry , this is not going to be a possibility.

While you could physically obtain and even fit the older manifolds and carbs - in that they would physically fit - making the car run properly would be a nightmare - if at all possible..

To explain, the engine that you have is not only controlled with the injection system- its engine management, engine / ignition timing is all controlled by an Ecu ( computer ) and that is controlled by inputs from various sensors - all of which are inextricably linked into the Ecu as above - without which , it just would not run / work. You would have to change the engine, the ignition system and fuel system complete for a non injected type - its not feasible Im afraid to do that --- Im really sorry to be the bearer of that news...but that is the case here..

Its a lot more complicated than what I have outlined - I have really just given the basics there -

If there is anything more by all means get back to me and we can carry on...
