Peugeot 207 GT lack of power

[i_shot_the_sheriff]

Good evening mates,

Just having some crazy problems with a Peugeot 207 GT 1.6 with engine code 5FX!
The car is about 150 HP by Peugeot! When i drove it it was like 90 or something! NO TURBO at all!

The client told me that he changed the whole engine and the turbine itself!
Well i've connected the Peugeot Planet on it and i've seen that the pressure of the turbo is about 1600psi when accelerating! Peugeot says it must be around 1800-2000psi!! I'm not sure if that shows anything but what the heck? With a new turbine?? :O

Do you have anything to suggest?

Thanks in advance

I think you are comparing the fuel pressure with the turbo pressure. Turbo pressure is in bars in single digits - in psi 2 digits, but not higher than that. N.B.: 1600 psi = 110 bar, 2000 psi = 138 bar.

Any fault codes present?

Ohh yeah! I think your right!
Well no DTC at all! Thats the curious about this fault!!

[oldford]

Maybe exhaust blocked?
Any history known?

Hi

Was the Engine been replaced because of this problem or, for some other reason...........

Also what is the inter-cooler radiator condition ?

It could be blocked IF, the old Engine was passing oil from the turbo and causing intake air starvation..........worth checking it....

Seen a lot of these with the camtiming complete off.
There is no key in the cam sprocket.

Just a thought.

Well the client bought the car new and at 30.000 he got the engine to his hands!!! AFter that, he changed it with a used one!
He also changed the whole exhaust system too!

Anyway, the engine is not opened! No one opened the engine, they just adjusted it on the car!

AS for the intercooler i've just checked it and it's ok!

Still check the cam timing. Specially the inlet cam.
There are several modifications for it.

I will today!

Just another note i wanted to say! There is a small valve that is called Turbocharger wastegate regulating valve and it's under the intake manifold!

Autodata says it must have Ohm at around 20-40! I've measured it and it shows 16Ohm!
The problem is that autodata says that the 20-40Ohm; value is a general one!
Does anyone knows if the 16Ohm measurment is a correct one?

Note that one of the pipes coming out of this valve goes to the wastegate!

Just put another boost pressure solenoid for testing. It could be that.For first i would check vacuum/boost pressure leaks on turbocharger. Is it wastegate or variable wanes turbocharger?
If i understand right this is petrol common rail (direct injection) system. What is low side fuel pressure? What is fuel pressure in fuel rail(high pressure side)? Is it getting worse when it's hot?
Just check all things on the road under load.
