Thank you guys, small update i have been getting the car ready for a dyno session to finish mapping of higher load areas and get as much power as the turbo allows. I was also getting way too much fuel smell in the car so I have changed the fuel hoses in the boot to petrol compatible lowest permeation hose available, and so far it has been great no more getting high on petrol for me .Since the last dyno session I upgraded the fuel pump to Bosch 044 which induced a couple small issues, The base fuel pressure went up 4psi and 044 was much noisier than my other pump. I could have easily tuned around the slight pressure increase, in fact close loop 02 had taken care of it anyway I still wanted to try and reduce the noise of the pump. So after a bit of testing I decided to add a 2 speed(lo/hi) fuel pump control, and now I can barely hear the pumps and the fuel pressure is back to normal base pressure  this should also heat the fuel less and probably make the pump last longer as it is running at much lower rpm.
 
Here is a pic of new hoses

Here is a dyno graph from the engine run in/initial tune session, running wastgate spring pressure boost of 6psi but overcomes to just under 10 psi in the top end.

Hi
Seeing the boot I remember i was supposed to get you some information
Below is a reslient mount used to support electrical enclosures on the Cummins gensets at work and as it's very plyable and would be the ideal size to use when mounting fuel pumps etc.
They have a 5/16 UNC blind thread each end and I recon they're <$15ea.

recon that 170rwkw would be just spot on in an escort, well done.. cant wait too see this in the flesh

Thanks Paul,
Sundowner, it goes well as it is but there is more coming. I am going back on the dyno on tuesday if all goes well, I say that because last night I had a little mishap and killed one of the drivers in the ecu, I should see replacement one tomorrow and hopefully it will all be ready by the end of the weekend.
 
Zapped driver

Cheers

Well as per usual next day delivery promise by online store hasn't happened and my replacement ecu driver didn't get to me on friday. Ater a bit of testing of the ecu board I worked out that there is a few spare drivers on the board normally used in E11 ecu so I was able to remove one of those and replace the one I zapped earlier, and now it is all good to go for tuesday. I've just been for a drive to make sure that there is no issues on tuesday,and it went well it loved the 20 deg. temps. Spanked this wrx while I was out, (Whats in it? 2lt turb.  Is that all!!!!) I'm very keen to get back on the dyno and finish the tune, I'll keep you posted...
cheers
 
Dropped in the servo on the way back and took a shot with my phone

Hi,
My dyno session yesterday was cut short due to wastgate being held open in the top end. Its a combination of standard (soft) 5psi wastegate actuator and pre turbo exhaust backpressure. I did manage do to some mapping up top but it will need to be finished later. I do have a brand new 12-14 psi adjustable actuator (Garrett 480009-6) to put on, just need to find time to do it. It made 196rwkw @12.5psi. As soon as boost is sorted I'll go back on dyno to finally finish.
 
Here is the latest dyno graph, boost control solenoid is at 100% duty cycle from 110km/h (disregard boost oscillating, as that is just incorrect closed loop boost control settings, there was no point wasting time as it will need re setting with new actuator)
Cheers
