I have the opportunity to get a brand new GT2052V and I was thinking of plugging it onto my 200tdi. Now I know I will have to make all the flanges and plumbing fit, but what I don't know about is the vane control.
I understand that this is normally done by the ecu via a vacuum solenoid, but what can I do in my case? Is it just a case of plumbing it into the vacuum line on the top of the fuel pump?
I have seen this guy's setup , but I don't necessarily want to adjust the boost. So fitting something similar without the needle valve and only a dawes valve to limit the boost should be what I want to do, correct?
I look forward to a turbo guru to lend me a bit of advice!
I posted the above in a hurry and on reflection now realise that the fuel pump uses boost pressure at that point. So, that's no good.
The only vacuum reference point is at the vacuum pump, providing vacuum pressure to the brakes. Is this any good to me?
I realise I am putting in a vacuum actuated device into a spot that a pressure actuated device goes. Is this all too hard or is there some way of getting the vacuum signal I need.
Swap the vacuum actuator for a boost pressure waste gate actuator from a normal turbo (or from your existing turbo.
I had this one on a 300Tdi - tee fitting in the compressor outlet supplied boost pressure signal to the actuator for the vane control and the boost compensator on the injection pump.
Like John mentioned, just fit a pressure actuator instead.
Many newer wastegate actuators use the same two bolt attachment that that vacuum actuator uses. You'll need to cut and thread the shaft to the required length.
There are plenty of people on the net who've done it, especially on older VW's. Some have even cut open the vacuum actuator and flipped the spring to the other side to make a pressure actuator.
I had the same idea this arvo and I am glad that you've confirmed that it would work. I had a quick gander at the two actuator shafts and they even look like they are the same thread. bonus!
I don't think I will be cutting it open if I can help it!
BTW, John: I love all the silicone pipe in your picture!
