Alfa 159i Performance Upgrade
Posted: Fri May 25, 2007 2:56 am
Hey,
During the mid 80's in South Africa, a few very special Alfas were born. We are probably all aware of the great 3.0 GTV6's of those days! Now, another model, just as rare, was the Alfa 159i that was born as a "last of the range" breed to celebrate the best of the last Alfettas.
I have one of these cars and it is fitted with the classic 2.0 twin cam motor with single spark head, but has the variable intake valve timing fitted, and set up for fuel economy rather that sportiness. In stock form it delivers 97kW (130BHP) and 183Nm of torque, along with longer gear ratios. The performance is quite good for an engine developed for good fuel economy.
I would like to know if anyone else out there knows what modifications can be done to this engine in order to provide some more serious poke? I am planning on rebuilding the car completely into a stunner, but am looking for around 170bhp from the engine.
The original pistons are borgo 10:1 and the valve sizes are Inlet 44mm and exhaust 41mm. The 10.4:1 pistons don't work because of the VIVT.
