Jos jedanput sam provjerio podatke ...
Grim: sigurno postoji razlika izmedju starog D5 i novog 2.4D ... Ako nista drugo, razlika u kompresiji to pokazuje.
tcode: Nemam nigdje podataka o "periferiji". Blok motora je sigurno isti, dok turbina ... Ne znam.
Ipak ostajem kod misljenja da je razlika samo u softwareu, inace mi nije jasno zasto tuneri ne bi koristili potencial vecih turbina i slicnog. Nisam nasao niti jednog tunera, koji bi npr. novog D5 tunirao na vise konja nego novog 2.4D.

Citat:
There are two generations of D5 engines. The first generation was introduced in 2001; the second generation was introduced in 2005. The second generation has a reduced compression ratio, a water cooled VNT turbocharger with a bigger compressor and an electric servo motor to adjust the vanes, an improved EGR system, a throttle valve, revised intake and exhaust ports and a newer generation of common-rail direct injection with improved injectors.
Volvo has a special version of the D5 for use in the S40, V50 and C70 models that produces 180 hp and 350 NM of torque. The engine compartments of these cars are smaller so the engine has a different intake manifold and other parts.
