Autodelta SZ

Autodelta SZ | Engine

The Alfa Romeo SZ has become a legend due to its superb handling and original styling. For those who seek more performance out of the original 210 bhp 3.0 V6 engine, look no further than Autodelta. Autodelta offer two high-output engines, with the first 3.5-litre series being launched back in 1992.

With gas-flowed cylinder heads, the fuel-injected SZ powerplant is bored out to 3.5 litres and fitted with forged pistons. The compression ratio is hereby increased and the moving parts are dynamically balanced. The ECU is also remapped to give improved ignition and fuelling, and removing the catalytic converter releases a few more horsepower. A high-flow air filter completes the conversion to boost power output typically to 256 bhp at 6,200 rpm before the rev limiter cuts in at 6,800 rpm. An impressive torque curve with a very flat band of over 230 lb ft between 3,250 and 5,500 rpm results in tarmac eating performance. To date nine of these 3.5 litre SZ conversions have been made for customers worldwide.
