Parrot of doom, Im in the uk too, birmingham, got the car from not far away from you, so my car is also RHD. I reckon Im getting I'm getting 0-60 in about 16 secs, I can't hear the turbo AT ALL when accelerating. I got my mate to sit in the car and rev it with the bonet open, no sweet whining sound to pierce my ear drum not even a hint of it....

Shame about the exhaust manifold Flange, but i wont let it stop me!! The other option for me is a hybrid of this KKK turbo. I couldnt see an actuator arm on hte turbo from my initial inspection, is it underneath? if there isn't one then how is the boost controlled. Also is there anybody out there thats had this turbocharger modified?

I have had exactly the same fault. No real idea what it was but swapping those 2 transducers solved it. It hasn't happened since, it was over 6 months ago, so I'm presuming either a bad connection or some cack in the line.

Do that first. You'll know when its working, you'll get a ruddy great shove in the back....

AFAIK the ECU controls boost.


BTW, I found a load of interesting piccies here:

I suggest anyone interested saves them for reference

You won't. I can't hear mine until I had it chipped.

WOW!!! Parrot, thats quite a big turbo!

There isn't much hope of using the stock turbo to make a hybrid. It's a KKK K14. To this day I'm amazed it can even flow enough air for the stock engine. The turbine on the K14 is TINY, horrible for any kind of power.

Look at how tiny that thing is compared to the engine. The last picture is a custom manifold made for the 606.

Forced Induction, if sticcking with the KKK turbo isnt an option, do you think that my vnt25 will be good for any power gains?

Parrot of doom, the two pipes that you told me to change did you mean swap them over in top so that they are routing into the different place or swap the pipes over so that theyre routing in the same place.

When I looked at them one of them was disconnected from where it goes into uner the inlet manifold, i reconnected it but this has seemed to make very little difference. I found one of the cone air filters, It looks Knackered!! but at least its there.

Are those pipes a good place to tap in a boost gauge btw??? so i can check that the turbo is providing boost... what should it be putting out?? 15psi?

Depends. If you mean a GT25V, then yes it will be good. If you mean the VNT25 used on the Dodge Shelby's, then no its way too small.

Indeed I do mean gt2556v.

I'll just throw this in the pot: One time the line to my MAP sensor popped off and the ECU wouldn't allow any fuel because it wasn't seeing any boost. This resulted in similar behavior to what you describe. No codes thrown BTW...

There are 2 black cylinders. One is underneath the air filter box. The other is in front of the ABS pump.

They are both identical. Swap them over. Don't change the configuration of the lines.

If once they've been swapped, your turbo starts working, then you know that one of those actuators is dead.

If the cone filters (there are two, one for each actuator) are in ropey condition, get some new ones.

I don't think you need a boost gauge until you check those. You'll know when the turbo is working by the almighty great shove in your back when you floor it. It is also quite a whistley unit so you'll hear it also.

Part 53 in this diagram - these are to what I refer:

http://www.detali.ru/cat/oem_mb2.asp?TP=1&F=210225&M=606%2E962&GA=722%2E608&CT=M&cat=19T&SID=14&SGR=170&SGN=09



The diagram shows three - one of them is an illustration only.

While you've got the vacuum lines off, if possible, see that the lines are clear of any debris or blockages (or leaks).

Just noticed that that site shows it as a 'converter' or a 'transducer'. I think I'll refer to them as transducers now.

BTW - I have never heard my turbo spool up when not moving. I don't think it does.

You have to be driving to activate it.

Excellent, i see what you mean now, The actual plastic unit thing, that shouldn't be too hard a job I'll have a go at it tomorrow. Thanks for the advice

I've been taking apart my turbo tonight, one of the blades is chipped on the exhaust wheel, does anyone know where i can get a new one from??

well i cahnged them over this morning and took it out for a test but still no difference, still cant hear the turbo and still slow. I think maybe the only thing left to do is take it to a specialist

I tried unplugging the maf today, and its faster pulling more strongly higher up but throwing a fault, does this mean that my problem is definately the MAF then??
