Currently running an 1800 Zetec on motorcycle carbs, runs well but due to the size of the engine bay I'm restricted to downdraft style carbs - these can get significant needle and seat wear so that mid range and top end fuelling becomes very erratic. (Even a known issue on some bikes as well) So thinking about replacing the setup with a single 32/36 Weber.
Anybody else running one of these on an 1800 Zetec? If so what jet sizes etc are you running? Also anyone got a decent Megajolt map for an 1800 Zetec as I'm simply running the base map (although it's pretty good on that anyway)
I have no room to fit standard injectors, throttle bodies dell orto's etc so other than down drafts or some very funky one off manifold to move positioning I am limited to the single carb option

Any help with a jetting starting point much appreciated.
Cheers

 

Any pics of the engine bay that it is in? Or what car.

Is there no way you can get this on to standard injection with modified plenum or proper throttle bodies, even if you need some engine bay fabrication...seems wrong to move backwards in technology
