Ferrari 308 GTSi

Ferrari 308 GTSi

The goal of this engine was to make the most power possible with a 2-valve 308 engine using the standard Bosch CIS fuel injection system.
The CIS version of the 308 2-valve series was infamous for being the weak sister of all the 308 variants. Stock power was in the 185-195 HP range and acceleration was anemic.
We applied our 3.5L technology to this 2- valve engine and were satisfied with the results. The power and torque increases have transformed the driving experience of this 308 to what it should have been from the factory and now it is fast!
