Garret 2256vk
« on: March 14, 2011, 06:21:35 am »
GT2256V- 2001-2006 Dodge/Freightliner/Mercedes Sprinter 2.7L CDI.
NOTE: The compressor housing covers are not interchangeable between the 01-03 and 04-06 series turbos. The 04-06 has a slightly larger (.5mm) compressor inducer.

Compressor
Inducer: 40.3mm
Exducer: 56mm (51.8 Trim)
Housing Inlet: 60mm
Housing Outlet: 35mm
.53 A/R

Turbine
Inducer: 49.4mm (est.)
Exducer: 41.7mm
.64 A/R

On a 1.6 Will this work? OR how will this work is what I should be asking.

The 270CDI turbo is not a VK, it has the vacuum actuator so it's a GT2256V. If you're going big VNT why don't you go for the newer and quicker spooling /lower EMP generation, the GTB? GTB1756VK, GTB2056VK, GTB2260VK etc.

How are you planning to control the VNT mechanism?

I am just wondering what it will do on a daily. I am sure it will make power up top, but what about down low? The problem I have now is not enough cold air to run more fuel. This should do it I am hoping, but at what cost to low rpm power?

I don't think there is much info on using the larger vnts on IDI engines. I have a gt2559v I am putting on AAZ with mechanical vnt control and how no idea how it will be for lower end response. Similar reasons as you. I got the gt2559v for an incredible price so why not slap it on there, right?
