What Type of Turbo is in a 2007 3lt 300C CRD?

Also does anyone know if you can modifiy the turbo or if a bigger turbo can be fitted? Anyone done this before?

You can get a hybrid turbo or send yours off to a specialist who will uprate bearings/internals etc. Pretty pricy at £600 ish plus though as far as I've heard.

(STOCK) Garrett GT2056v

You can fit a GT2260vklr (Plug and play with minor alterations) should see over 300bhp

You can proberly buy a hybrid that will most likely incorporate the 2260vklr internals

If your going for a larger intercooler make sure its not too large for your setup, most coolers you can buy for the 300c are rated at 600 bhp ! serious overkill, it may look "cool" but with the increased volume it will cause a large pressure drop from hot side to cold side giving you less bhp, will also cause throttle lag :)

without boring you with volumes, pressures, cross sectional areas ect a 1/3 bigger than stock or half the size of a 600 bhp one :)

So half of the cooler is not subject to airflow plus its over increased volume causing pressure drop and lag

I cant say i have any increase lag, but with any size larger that the stock the crossmember is blocking the airflow as there is no room either side or down so it has to go up.

i can understand what you mean. with half the cooler being colder than the other

I agree, you also have cooler depth to play with to a certain degree, the larger the volume the more time it takes for the cooler to charge, more time equals lag, a 600bhp rated cooler is pointless if you only have half that power

A oversized cooler will also cause pressure drop, so if your map is requesting 1.8 bar by the time it exits the cooler ready to feed your inlet it may only be 1.6 bar

I know of this guy and tuner... he talks a lot of truth ......260-270 is the max on the std turbo, regardless of what supporting mods you have or what dyno (lottery) you are using :)

ok so my cooler core size is 600mm x 300mm x76mm deep, would a 560m x Height 230mm x 65mm ( top 30mm still behind cooler)be better.
Oh great! So Paul, re the intercooler you fitted, and supplied to some of us on here, was there any research that you did to ascertain that that particular size was what was needed to do the job? Please don't tell me it was just guess work.

I think performance tells the real story, of the people that have fitted the larger intercooler no one to my knowledge has complained about lag after fitting and I'm sure if after fitting the intercooler lag was experienced by anyone I'm sure it would have been mentioned.

It has been mentioned Tim, can't remember which thread it was on though. I still get some lag even with the performance map installed, but to be fair, I don't think it's as bad as the original wait, whistle and hope scenario we used to get. My main problem is that I just don't use the car enough, I'm still on less than 8000 miles. I may refit the original intercooler at some stage just to see if there's any difference, but I'll need to get a lot more miles on it as is first.
