K03-1 NHSV ALFA ROMEO 147

How much power does a K03 have?
In terms of power, the K03 has the least juice meaning that with proper add-ons to accompany, it will top out at 190 bhp. You may get more but the life of the turbo will be reduced. The K03s has higher power output. Most people have achieved 215 bhp with K03s which is the safe limit, any more and turbo life will be compromised.
When did Alfa Romeo make a 147?
In 2007, the 147 1.9 JTD Q2 version was launched, with a front Torsen limited slip differential. Alfa Romeo presented a new limited edition 147 called Ducati Corse at the 2007 Bologna Motor Show.
