Tuning Giulietta 116
Hi there Alfisti,
My 116 series Giulietta 2l 1985 model is one of my long term projects. I need more info on tuning/modifying this car.
So far I have done the following to the engine: Enlarged ports and smooth ports, 3 angle valve seats, Group One cams (10.9 mm lift with 280 deg. duration) and 57mm straight through exhaust.
I need more info on the following please:
1)Is a K&N panel filter worthwile, as the standard paper element has a large area?
2)So far my jets are standard. (1.38 on 40mm Webers) My home town is about 2000 meters above sea level. Any recommendations on jets will be appreciated. I am not very keen on dyno tuning unfortunately.
3)Do "sport" ignition coils make a difference?
4)Has anybody got experience regarding power timing these cams? Advance/retard which cams?
At the moment only the inlet cam is advanced 4,5 degrees from the std timing mark. Exhaust cam is on normal marking.
To conclude, the car is quite powerfull as it is at the moment, and can easily out accelerate a std model, but I feel the car has more potential and tuning possibilities.
Thanks in advance.
